New Features in AnyConnect 4.3.02039

AnyConnect 4.3.02039 is a maintenance release that includes the following feature and enhancements and that resolves the defects described in AnyConnect 4.3.02039 .

Hostname Option Added to Static Exception in Profile Editor

You can exclude or include endpoint traffic from Cisco Cloud Web Security Scanning using AnyConnect's Web Security profile editor. With Cisco AnyConnect Secure Mobility Client release 4.3.02039 or later, you can now add hostnames, besides just IP addresses, to exclude from scanning. In the Static Exception field of the profile editor, determine what hostname to exclude from scanning, and Web Security will not forward that HTTP/HTTPS traffic to the Cloud Web Security Proxy for inspection. If you have multiple hostnames with the same IP address but only one of the hostnames is configured in the Static Exceptions list, Web Security exempts the traffic.

If you want to exempt any browser traffic via proxy server, you must list those hostnames in Host Exceptions, so that they are not forwarded. You cannot only configure static exceptions for traffic flowing through proxies not listed in the Proxy Exception list.

New Features in AnyConnect 4.3.01095

AnyConnect 4.3.01095 is a maintenance release that introduces the Cisco Umbrella Roaming Security module and resolves the defects described in AnyConnect 4.3.01095.

The Umbrella Roaming Security module requires a subscription to either Cisco Umbrella Roaming service or OpenDNS Umbrella services (Professional, Insights, Platform, or MSP). Cisco Umbrella Roaming provides DNS-layer security when no VPN is active, whereas OpenDNS Umbrella subscriptions add Intelligent Proxy and IP-Layer Enforcement features, both on- and off-network. Additionally, OpenDNS Umbrella subscriptions provide content filtering, multiple policies, robust reporting, active directory integration, and much more. The same Umbrella Roaming Security module is used regardless of the subscription.

The Umbrella Roaming module profile (OrgInfo.json) associates each deployment with the corresponding service, and the corresponding protection features are enabled automatically.

The Umbrella Dashboard provides real-time visibility into all of the Internet activity originating from the Roaming Security module. The level of granularity in policies and reports depends on the Umbrella subscription.

Refer to https://www.opendns.com/enterprise-security/threat-enforcement/packages/ for a detailed comparison of which features are included in which service level subscriptions.

Interoperability Using Both Umbrella Roaming Security and Web Security

To get full functionality when using both the Umbrella Roaming Security and Web Security module, you must configure the host exclusion and exclude static exceptions defined in the Web Security chapter: http://www.cisco.com/c/en/us/td/docs/security/vpn_client/anyconnect/anyconnect43/administration/guide/b_AnyConnect_Administrator_Guide_4-3/configure-web-security.html. Otherwise, the DNS protection could be completely bypassed.

New Features in AnyConnect 4.3.00748

AnyConnect 4.3.00748 is a major release that includes the following features and enhancements and that resolves the defects described in AnyConnect 4.3.00748.

  • In Network Visibility Module (NVM), adjustments to the rate at which data is sent from the cache to the collector.

  • Customization of the NVM timer so that an administrator can define when Cisco nvzFlow exports the data.

  • Broadcast and multicast options turned off as a default in NVM, with option to choose data collection methods.

  • Creation of anonymization profiles in NVM by including or excluding certain fields to anonymize, and then association of the profiles with a network type or connection scenario.

  • Other NVM enhancements such as the ability to know the edition of the operating system (OS), what is running in OS containers, and what interface attributes exist.

  • Ability to disable Network Access Manager-originated DHCP requests.

  • (Windows only) Detection by posture client of USB mass storage devices and the ability to block or deny access. This feature relies on the OPSWAT v4 compliance module.

  • The introduction of OPSWAT version 4, which combined antivirus and antispyware under an anti-malware umbrella. With ISE posture on AnyConnect release 4.3 (or later) or ISE 2.1 (or later), you can choose to use either OPSWAT v3 or v4.

  • Upon installation of Start Before Logon, the Network Connection button launches both AnyConnect VPN and Network Access Manager UI.

  • A new profile editor Preferences option where the match to certificates with no Extended Key Usage (EKU) can be disallowed.

  • More detailed information with certificates in the form of AnyConnect logs to better track certificate handling.

  • AnyConnect 4.3 has moved to Visual Studio (VS) 2015 build environment and requires VS redistributable files, which are installed as part of the install package.

  • Ubuntu 16.04 is a qualified Linux version.

Important Interoperability Considerations

Coexistence of ISE and ASA Headends

  • If you are using both ISE and ASA for client posture, the profiles must match on both headends.

  • AnyConnect ignores the ISE server if NAC Agent is provisioned for the endpoint.

  • If the Cisco NAC agent and the VPN Posture (HostScan) module are both installed on a client, the Cisco NAC agent must be at least version 4.9.4.3 or later to prevent posture conflicts.

  • The NAC Agent ignores the ISE server if AnyConnect is provisioned for the endpoint in ISE.

System Requirements

This section identifies the management and endpoint requirements for this release. For endpoint OS support and license requirements for each feature, see AnyConnect Secure Mobility Client Features, Licenses, and OSs.

Cisco cannot guarantee compatibility with other VPN third-party clients.

Changes to the AnyConnect Profile Editor

You must install the 32-bit version of Java, version 6 or higher, before installing the profile editor.

ISE Requirements for AnyConnect

ISE Release Requirements

  • ISE 2.0 is the minimum release capable of deploying AnyConnect software to an endpoint and posturing that endpoint using the new ISE Posture module in AnyConnect 4.0 and later.

  • ISE 2.0 can only deploy AnyConnect release 4.0 and later. Older releases of AnyConnect must be web-deployed from an ASA, pre-deployed with an SMS, or manually deployed.

ISE Licensing Requirements

To deploy AnyConnect from an ISE headend and use the ISE Posture module, a Cisco ISE Apex License is required on the ISE Administration node. For detailed ISE license information, see the Cisco ISE Licenses chapter of the Cisco Identity Services Engine Admin Guide.

ASA Requirements for AnyConnect

Minimum ASA/ASDM Release Requirements for Specified Features

  • You must upgrade to ASDM 7.5.1 to use NVM.

  • You must upgrade to ASDM 7.4.2 to use AMP Enabler.

  • You must upgrade to ASA 9.3(2) to use TLS 1.2.

  • You must upgrade to ASA 9.2(1) if you want to use the following features:

    • ISE Posture over VPN

    • ISE Deployment of AnyConnect 4.x

    • Change of Authorization (CoA) on ASA is supported from this version onwards

  • You must upgrade to ASA 9.0 if you want to use the following features:

    • IPv6 support

    • Cisco Next Generation Encryption “Suite-B” security

    • Dynamic Split Tunneling(Custom Attributes)

    • AnyConnect client deferred upgrades

  • You must use ASA 8.4(1) or later if you want to do the following:

    • Use IKEv2.

    • Use the ASDM to edit non-VPN client profiles (such as Network Access Manager, Web Security, or Telemetry).

    • Use the services supported by a Cisco IronPort Web Security Appliance. These services let you enforce acceptable use policies and protect endpoints from websites found to be unsafe, by granting or denying all HTTP and HTTPS requests.

    • Deploy firewall rules. If you deploy always-on VPN, you might want to enable split tunneling and configure firewall rules to restrict network access to local printing and tethered mobile devices.

    • Configure dynamic access policies or group policies to exempt qualified VPN users from an always-on VPN deployment.

    • Configure dynamic access policies to display a message on the AnyConnect GUI when an AnyConnect session is in quarantine.

ASA Memory Requirements


Caution

The minimum flash memory recommended for all ASA 5500 models using AnyConnect 4.0 or later is 512MB. This will allow hosting of multiple endpoint operating systems, and logging and debugging to be enabled on the ASA.

Due to flash size limitations on the ASA 5505 (maximum of 128 MB), not all permutations of the AnyConnect package will be able to be loaded onto this model. To successfully load AnyConnect, you will need to reduce the size of your packages (i.e. fewer OSs, no HostScan, etc,) until they fit on the available flash.


Check for the available space before proceeding with the AnyConnect install or upgrade. You can use one of the following methods to do so:
  • CLI—Enter the show memory command.

    
    asa3# show memory	
    Free memory:       304701712 bytes (57%)
    Used memory:       232169200 bytes (43%)
    -------------     ----------------
    Total memory:      536870912 bytes (100%)
    
  • ASDM—Choose Tools > File Management. The File Management window displays flash space.

If your ASA has only the default internal flash memory size or the default DRAM size (for cache memory), you could have problems storing and loading multiple AnyConnect client packages on the ASA. Even if you have enough space on the flash to hold the package files, the ASA could run out of cache memory when it unzips and loads the client images. For additional information about the ASA memory requirements and upgrading ASA memory, see the latest release notes for the Cisco ASA 5500 series.

VPN Posture and HostScan Interoperability

The VPN Posture (HostScan) Module provides the Cisco AnyConnect Secure Mobility Client the ability to identify the operating system, antivirus, antispyware, and firewall software installed on the host to the ASA.

The VPN Posture (HostScan) Module requires Cisco Hostscan to gather this information. Cisco Hostscan, available as its own software package, is periodically updated with new operating system, antimalware, and firewall software information. Cisco recommends that you run the most recent version of HostScan, which is the same as the version of AnyConnect.

The List of Antimalware and Firewall Applications is available on cisco.com. The support charts opens most easily using a Firefox browser. If you are using Internet Explorer, download the file to your computer and change the file extension from .zip to .xlsm. You can open the file in Microsoft Excel, Microsoft Excel viewer, or Open Office.


Note

AnyConnect will not establish a VPN connection when used with an incompatible version of HostScan. Also, Cisco does not recommend the combined use of HostScan and ISE posture. Unexpected results occur when the two different posture agents are run.


ISE Posture Compliance Module

The ISE Posture compliance module contains the list of supported antimalware and firewall for ISE posture. While the HostScan list organized by vendor, the ISE posture list organizes by product type. When the version number on the headend (ISE or ASA) is greater than the version on the endpoint, the OPSWAT gets updated. These upgrades are mandatory and happen automatically without end user intervention.

The individual files within the library (a zip file) are digitally signed by OPSWAT, Inc., and the library itself is packaged as a single, self-extracting executable which is code signed by a Cisco certificate. Refer to the ISE compliance modulesfor details.

IOS Support of AnyConnect

Cisco supports AnyConnect VPN access to IOS Release 15.1(2)T functioning as the secure gateway; however, IOS Release 15.1(2)T does not currently support the following AnyConnect features:

  • Post Log-in Always-on VPN

  • Connect Failure Policy

  • Client Firewall providing Local Printer and Tethered Device access

  • Optimal Gateway Selection

  • Quarantine

  • AnyConnect Profile Editor

For additional limitations of IOS support for AnyConnect VPN, please see Features Not Supported on the Cisco IOS SSL VPN.

AnyConnect Support for Microsoft Windows

Windows Requirements

  • Pentium class processor or greater.

  • 100 MB hard disk space.

  • Microsoft Installer, version 3.1.

  • Upgrading to Windows 8.1 from any previous Windows release requires you to uninstall AnyConnect, and reinstall it after your Windows upgrade is complete.

  • Upgrading from Windows XP to any later Windows release requires a clean install since the Cisco AnyConnect Virtual Adapter is not preserved during the upgrade. Manually uninstall AnyConnect, upgrade Windows, then reinstall AnyConnect manually or via WebLaunch.

  • To start AnyConnect with WebLaunch, you must use the 32-bit version of Firefox 3.0+ and enable ActiveX or install Sun JRE 1.4+.

  • ASDM version 7.02 or higher is required when using Windows 8 or 8.1.

Windows Limitations

  • AnyConnect is not supported on Windows RT. There are no APIs provided in the operating system to implement this functionality. Cisco has an open request with Microsoft on this topic. Those who want this functionality should contact Microsoft to express their interest.

  • Other third-party product’s incompatibility with Windows 8 prevent AnyConnect from establishing a VPN connection over wireless networks. Here are two examples of this problem:

    • WinPcap service “Remote Packet Capture Protocol v.0 (experimental)” distributed with Wireshark does not support Windows 8.

      To work around this problem, uninstall Wireshark or disable the WinPcap service, reboot your Windows 8 computer, and attempt the AnyConnect connection again.

    • Outdated wireless cards or wireless card drivers that do not support Windows 8 prevent AnyConnect from establishing a VPN connection.

      To work around this problem, make sure you have the latest wireless network cards or drivers that support Windows 8 installed on your Windows 8 computer.

  • AnyConnect is not integrated with the new UI framework, known as the Metro design language, that is deployed on Windows 8; however, AnyConnect does run on Windows 8 in desktop mode.

  • HP Protect tools do not work with AnyConnect on Windows 8.x.

  • Windows 2008 is not supported; however, we do not prevent the installation of AnyConnect on this OS. Also, Windows Server 2008 R2 requires the optional SysWow64 component

  • If you are using Network Access Manager on a system that supports standby, Cisco recommends that the default Windows 8.x association timer value (5 seconds) is used. If you find the Scanlist in Windows appears shorter than expected, increase the association timer so that the driver can complete a network scan and populate the scanlist.

Windows Guidelines

  • Verify that the driver on the client system is supported by Windows 7 or 8. Drivers that are not supported may have intermittent connection problems.

  • For Network Access Manager, machine authentication using machine password will not work on Windows 8 or 10 / Server 2012 unless a registry fix described in Microsoft KB 2743127 is applied to the client desktop. This fix includes adding a DWORD value LsaAllowReturningUnencryptedSecrets to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa registry key and setting this value to 1. This change permits Local Security Authority (LSA) to provide clients like Cisco Network Access Manager with the Machine password. It is related to the increased default security settings in Windows 8 or 10 / Server 2012. Machine authentication using Machine certificate does not require this change and will work the same as it worked with pre-Windows 8 operating systems.


    Note

    Machine authentication allows a client desktop to be authenticated to the network before the user logs in. During this time the administrator can perform scheduled administrative tasks for this client machine. Machine authentication is also required for the EAP Chaining feature where a RADIUS server can authenticate both the User and Machine for a particular client. This will result in identifying company assets and applying appropriate access policies. For example, if this is a personal asset (PC/laptop/tablet), and a corporate credentials are used, the endpoint will fail Machine authentication, but succeed User authentication and the proper network access restrictions are applied to the user's network connection.


  • On Windows 8, the Export Stats button on the Preferences > VPN > Statistics tab saves the file on the desktop. In other versions of Windows, the user is asked where to save the file.

  • AnyConnect VPN is compatible with 3G data cards which interface with Windows 7 or later via a WWAN adapter.

AnyConnect Support for Linux

Linux Requirements

  • x86 instruction set.

  • 64-bit processor.

  • 32 MB RAM.

  • 20 MB hard disk space.

  • Superuser privileges are required for installation.

  • libstdc++ users must have libstdc++.so.6(GLIBCXX_3.4) or higher, but below version 4.

  • Java 5 (1.5) or later. The only version that works for web installation is Sun Java. You must install Sun Java and configure your browser to use that instead of the default package.

  • zlib - to support SSL deflate compression

  • xterm - only required if you're doing initial deployment of AnyConnect via Weblaunch from ASA clientless portal.

  • gtk 2.0.0.

  • gdk 2.0.0.

  • libpango 1.0.

  • iptables 1.2.7a or later.

  • tun module supplied with kernel 2.4.21 or 2.6.

AnyConnect Support for Mac

Mac Requirements

  • AnyConnect requires 50MB of hard disk space.

  • To operate correctly with Mac, AnyConnect requires a minimum display resolution of 1024 by 640 pixels.

Mac Guidelines

  • Mac OS X 10.8 introduces a new feature called Gatekeeper that restricts which applications are allowed to run on the system. You can choose to permit applications downloaded from:
    • Mac App Store

    • Mac App Store and identified developers

    • Anywhere

    The default setting is Mac App Store and identified developers (signed applications). AnyConnect is a signed application, but it is not signed using an Apple certificate. This means that you must either select the Anywhere setting or use Control-click to bypass the selected setting to install and run AnyConnect from a pre-deploy installation. Users who web deploy or who already have AnyConnect installed are not impacted. For further information, refer to Apple documentation.


    Note

    Web launch or OS upgrades (for example 10.7 to 10.8) install as expected. Only the pre-deploy installation requires additional configuration as a result of Gatekeeper.


AnyConnect Licensing

For the latest end-user license agreement, see Cisco End User License Agreement, AnyConnect Secure Mobility Client, Release 4.x .

For our open source licensing acknowledgments, see Open Source Software Used in AnyConnect Secure Mobility Client..

To deploy AnyConnect from an ISE headend and use the ISE Posture module, a Cisco ISE Apex License is required on the ISE Administration node. For detailed ISE license information, see the Cisco ISE Licenses chapter of the Cisco Identity Services Engine.

To deploy AnyConnect from an ASA headend and use the VPN and VPN Posture (HostScan) modules, an AnyConnect 4.X Plus or Apex license is required, trial licenses are available, see the Cisco AnyConnect Ordering Guide.

For an overview of the AnyConnect 4.X Plus and Apex licenses and a description of which license the features use, see AnyConnect Secure Mobility Client Features, Licenses, and OSs.

AnyConnect Installation Overview

Deploying AnyConnect refers to installing, configuring, and upgrading the AnyConnect client and its related files. The Cisco AnyConnect Secure Mobility Client can be deployed to remote users by the following methods:

  • Pre-Deploy—New installations and upgrades are done either by the end user, or by using an enterprise software management system (SMS).

  • Web-Deploy—The AnyConnect package is loaded on the headend, which is either an ASA or ISE server. When the user connects to an ASA or to ISE, AnyConnect is deployed to the client.

    • For new installations, the user connects to a headend to download the AnyConnect client. The client is either installed manually, or automatically (web-launch).

    • Updates are done by AnyConnect running on a system where AnyConnect is already installed, or by directing the user to the ASA clientless portal.

  • Cloud Update—After the Umbrella Roaming Security module is deployed, you can update any AnyConnect modules using one of the above methods, as well as Cloud Update. With Cloud Update, the software upgrades are obtained automatically from the Umbrella cloud infrastructure, and the update track is dependent upon that and not any action of the administrator. By default, automatic updates from Cloud Update are disabled.

When you deploy AnyConnect, you can include the optional modules that enable extra features, and client profiles that configure the VPN and other features. Keep in mind the following:

  • All AnyConnect modules and profiles can be pre-deployed. When pre-deploying, you must pay special attention to the module installation sequence and other details.

  • The Customer Experience Feedback module and the Hostscan package, used by the VPN Posture module, cannot be web-deployed from the ISE.

  • The Compliance Module, used by the ISE Posture module, cannot be web-deployed from the ASA.

For more information about deploying the AnyConnect modules, see the Cisco AnyConnect Secure Mobility Client Administrator Guide, Release 4.6.

For more information about deploying the AnyConnect modules, see the Cisco AnyConnect Secure Mobility Client Administrator Guide, Release 4.5.

For more information about deploying the AnyConnect modules, see the Cisco AnyConnect Secure Mobility Client Administrator Guide, Release 4.3.


Note

Make sure to update the localization MST files with the latest release from CCO whenever you upgrade to a new AnyConnect package.


Upgrading from 3.1 MR10 AnyConnect Clients/Incompatibility Issues

Once AnyConnect 3.1.10010 has been automatically deployed to an endpoint, you cannot connect to a secure gateway configured with AnyConnect versions 4.0, 4.1, 4.1MR2, 4.2, and 4.3 which are incompatible. If you try to upgrade from AnyConnect 3.1 MR10 version to any version other than AnyConnect 4.1MR4 (or later) or 3.1 versions later than 3.1.10010, you will receive a notification that the upgrade is not allowed.

Refer to CSCuv12386 for further information.

Upgrading from AnyConnect 3.0 or Later

When you upgrade from AnyConnect Secure Mobility Client Release 3.0 or later, AnyConnect performs the following operations:

  • Upgrades all previous versions of the core client and retains all VPN configurations.

  • Upgrades any HostScan files used by AnyConnect.

Upgrading from AnyConnect 2.5 and earlier

When you upgrade from any 2.5.x version of AnyConnect, the AnyConnect Secure Mobility Client performs the following:

  • Upgrades all previous versions of the core client and retains all VPN configurations.

  • Upgrades any HostScan files used by AnyConnect.

  • If you install Network Access Manager, AnyConnect retains all CSSC 5.x configuration for use with Network Access Manager, then removes CSSC 5.x.

  • Does not upgrade or remove the Cisco IPsec VPN client. However, the AnyConnect client can coexist on the computer with the IPsec VPN client.

  • Does not upgrade and cannot coexist with Cisco’s ScanSafe AnyWhere+. You must uninstall AnyWhere+ before installing the AnyConnect Secure Mobility Client.


Note

If you are upgrading from the legacy Cisco VPN client, the MTU value on the physical adapters may have been lowered to 1300. You should restore the MTU back to the default (typically 1500) for each adapter to achieve optimal performance when using AnyConnect.

Upgrading from AnyConnect 2.2 is not supported using the ASA or Weblaunch. You must uninstall AnyConnect 2.2 then install the new verion either manually or using an SMS.


Web-based Installation May Fail on 64-bit Windows

This issue applies to Internet Explorer versions 10 and 11, on Windows versions 7 and 8.

When the Windows registry entry HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\TabProcGrowth is set to 0, Active X has problems during AnyConnect web deployment.

See http://support.microsoft.com/kb/2716529 for more information.

The solution to is to:

  • Run a 32-bit version of Internet Explorer.

  • Edit the registry entry to a non-zero value, or remove that value from the registry.


Note

On Windows 8, starting Internet Explorer from the Windows start screen runs the 64-bit version. Starting from the desktop runs the 32-bit version.


AnyConnect Support Policy

Cisco only provides fixes and enhancements based on the most recent 4.x release. TAC support is available to any customer with an active AnyConnect 4.x term/contract running a released version of AnyConnect 4.x. If you experience a problem with an out-of-date software version, you may be asked to validate whether the current maintenance release resolves your issue.

Software Center access is limited to AnyConnect 4.x versions with current fixes. We recommend that you download all images for your deployment, as we cannot guarantee that the version you are looking to deploy will still be available for download at a future date.

Guidelines and Limitations

Microsoft Inadvertently Blocks Updates to Windows 10 When Network Access Manager is Installed

Microsoft intended to block updates to earlier versions of Windows when the Network Access Manager is installed, but Windows 10 and Creators Edition (RS2) were inadvertently blocked as well. Because of the error (Microsoft Sysdev 11911272), you must first uninstall the Network Access Manager module before you can upgrade to the Creators Editor (RS2). You can then reinstall the module after the upgrade. Microsoft's fix for this error is planned for June 2017.

Windows 10 Defender False Positive─Cisco AnyConnect Adapter Issue

When upgrading to Windows 10 Creator Update (April 2017), you may encounter a Windows Defender message that the AnyConnect adapter has an issue. Windows Defender instructs you to enable the adapter under the Device Performance and Health section. In actuality, the adapter should be disabled when not in use, and no manual action should be taken. This false positive error has been reported to Microsoft under Sysdev # 11295710.

AnyConnect 4.4MR1 (or later) and 4.3MR5 are compatible with Windows 10 Creators Edition (RS2).

AnyConnect Compatibility with Microsoft Windows 10

AnyConnect 4.1MR4(4.1.04011) and later are compatible with Windows 10 official release. Technical Assistance Center (TAC) support is available beginning on 7/29/2015.

For best results, we recommend a clean install of AnyConnect on a Windows 10 system and not an upgrade from Windows 7/8/8.1. If you are planning to perform an upgrade from Windows 7/8/8.1 with AnyConnect pre-installed, make sure that you first upgrade AnyConnect prior to uprading the operating system. The Network Access Manager Module must be uninstalled prior to upgrading to Windows 10. After the system upgrade is complete, you can re-install Network Access Manager on the system. You may also choose to fully uninstall AnyConnect and re-install one of the supported versions after upgrading to Windows 10.

New Split Include Tunnel Behavior (CSCum90946)

Formerly, if a split-include network was a Supernet of a Local Subnet, the local subnet traffic was not tunneled unless a split-include network that exactly matches the Local Subnet was configured. With the resolution of CSCum90946, when a split-include network is a Supernet of a Local Subnet, the Local Subnet traffic is tunneled, unless a split-include (deny 0.0.0.0/32 or ::/128) is also configured in the access-list (ACE/ACL).

The new behavior requires the following configurations when a Supernet is configured in the split-include and the desired behavior is to allow LocalLan access:

  • access-list (ACE/ACL) must include both a permit action for the Supernet and a deny action for 0.0.0.0/32 or ::/128.

  • Enable Local LAN Access in the AnyConnect profile (in the Preferences Part 1 menu of the profile editor. (You also have the option to make it user controllable.)

Microsoft Phasing out SHA-1 Support

A secure gateway with a SHA-1 certificate or a certificate with SHA-1 intermediate certificates may no longer be considered valid by a Windows Internet Explorer 11 / Edge browser or a Windows AnyConnect endpoint after February 14, 2017. After February 14, 2017, Windows endpoints may no longer consider a secure gateway with a SHA-1 certificate or intermediate certificate as trusted. We highly recommend that your secure gateway does not have a SHA-1 identity certificate and that any intermediate certificates are not SHA-1.

Microsoft has made modifications to their original plan of record and timing. They have published details for how to test whether your environment will be impacted by their February 2017 changes. Cisco is not able to make any guarantees of correct AnyConnect operation for customers with SHA-1 secure gateway or intermediate certificates or running old versions of AnyConnect.

Cisco highly recommends that customers stay up to date with the current maintenance release of AnyConnect in order to ensure that they have all available fixes in place. The most up-to-date version of AnyConnect 4.x and beyond are available Cisco.com Software Center for customers with active AnyConnect Plus, Apex, and VPN Only terms/contracts. AnyConnect Version 3.x is no longer actively maintained and should no longer be used for any deployments.


Note

Cisco has validated that AnyConnect 4.3 and 4.4 (and beyond) releases will continue to operate correctly as Microsoft further phases out SHA-1. Long term, Microsoft intends to distrust SHA-1 throughout Windws in all contexts, but their current advisory does not provide any specifics or timing on this. Depending on the exact date of that deprecation, many earlier versions of AnyConnect may no longer operate at any time. Refer to Microsoft's advisory for further information.


Authentication Failure When Using a SHA512 Certificate for Authentication

(For Windows 7, 8, and 8.1 users) When the client uses a SHA512 certificate for authentication, authentication fails, even though the client logs show that the certificate is being used. The ASA logs correctly show that no certificate was sent by AnyConnect. These versions of Windows require that you enable support for SHA512 certificates in TLS 1.2, which is not supported by default. Refer to https://support.microsoft.com/en-us/kb/2973337 for information on enabling support for these SHA512 certificates.

No Longer Supporting RC4 TLS Cipher Suite

RC4 TLS cipher suites are not supported from AnyConnect release 4.2.01035 and onwards due to security policy enhancements.

OpenSSL Cipher Suites Changes

Because the OpenSSL standards development team marked some cipher suites as compromised, we no long support them beyond AnyConnect 3.1.05187. The unsupported cipher suites include the following: DES-CBC-SHA, RC4-SHA, and RC4-MD5.

Likewise, our crypto toolkit has discontinued support for RC4 ciphers; therefore, our support for them will be dropped with releases 3.1.13011 and 4.2.01035 and beyond.

Network Visibility Module Incompatible with LittleSnitch Firewall

The Network Visibility Module is incompatible with LittleSnitch firewall on Mac OS X.

AnyConnect Support on Mac OS X El Capitan 10.11

The Cisco AnyConnect Secure Mobility Client is supported on the Mac OS X El Capitan 10.11 operating system.

Using Log Trace in ISE Posture

After a fresh installation, you see ISE posture log trace messages as expected. However, if you go into the ISE Posture Profile Editor and change the Enable Agent Log Trace file to 0 (disable), you must do an AnyConnect service restart to get expected results.

Interoperability With ISE Posture on Mac

If you are using Mac OS X 10.9 or later and want to use ISE posture, you may need to do the following to avoid issues:

  • Turn off certificate validation to avoid a "failed to contact policy server" error during posture assessment.
  • Disable the captive portal application; otherwise, discovery probes are blocked, and the application remains in pre-posture ACL state.

Firefox Certificate Store on Mac OS X is Not Supported

The Firefox certificate store on Mac OS X is stored with permissions that allow any user to alter the contents of the store, which allows unauthorized users or processes to add an illegitimate CA into the trusted root store. Anyconnect no longer utilizes the Firefox store for either server validation or client certificates.

If necessary, instruct your users how to export your AnyConnect certificates from their Firefox certificate stores, and how to import them into the Mac OS X keychain. The following steps are an example of what you may want to tell your AnyConnect users.

  1. Navigate to Firefox > Preferences > Advanced, Certificates tab, click View Certificates.

  2. Select the Certificate used for AnyConnect, and click Export.

    Your AnyConnect Certificate(s) will most likely be located under the Authorities category. Verify with your Certificate Administrator, as they may be located under a different category (Your Certificates or Servers).

  3. Select a location to save the Certificate(s), for example, a folder on your desktop.

  4. In the Format pull down menu, select X.509 Certificate (DER). Add the .der extension to the certificate name, if required.


    Note

    If more than one AnyConnect Certificate and/or a Private Key is used/required, repeat the above process for each Certificate).


  5. Launch KeyChain. Navigate to File, Import Items…, and select the Certificate that you exported from Firefox.

    In the Destination Keychain:, select the desired Keychain. The login Keychain that is used for this example may not be the one used at your company. Ask your Certificate Administrator to which Keychain your certificate(s) should be imported.

  6. In the Destination Keychain:, select the desired Keychain. The login Keychain that is used for this example may not be the one used at your company. Ask your Certificate Administrator to which keychain your certificate(s) should be imported.



  7. Repeat the preceding steps for additional Certificates that are used or required for AnyConnect.

AnyConnect UI Fails Due to Missing Dependency libpangox

On many newer Linux distributions, the AnyConnect UI may fail to start with the error:
error while loading shared libraries: libpangox-1.0.so.0: cannot open shared
object file: No such file or directory
The missing library is obsolete and is no longer available. This impacts other applications, not just AnyConnect.

Pango has released the source code of a compatible library that has been built by others and is available online. To resolve this problem, find and install either the package pangox-compat-0.0.2-2.el7.x86_64.rpm or pangox-compat-0.0.2-3.fc20.x86_64.rpm.

SSLv3 Prevents HostScan From Working

(CSCue04930) HostScan does not function when the SSLv3 options SSLv3 only or Negotiate SSL V3 are chosen in ASDM (Configuration > Remote Access VPN > Advanced > SSL Settings > The SSL version for the security appliance to negotiate as a server). A warning message displays in ASDM to alert the administrator.

Problems Due to Modified sysctl Network Settings

We have seen instances where Apple's Broadband Tuner application (from 2005) was used with Mac OS X 10.9, That application changes the network settings in sysctl.conf, which can cause connection problems. That application was designed for much older versions of the Mac OS. We suspect that the current default OS settings take broadband networks into consideration, so most users will not need to take any action.

Running AnyConnect 3.1.04074 along with the modified sysctl settings may generate the following message:


The VPN client driver encountered an error..please restart

To Verify

To verify that the sysctl network setting is the cause of the problem, open a Terminal window and type:


sysctl -a | grep maxsockbuf

If the results contain a value much lower than the default value of 8388608, for example:


kern.ipc.maxsockbuf: 512000

Then this value may have been overritten in /etc/sysctl.conf by Apple's Broadband Tuner application

To Fix

Edit /etc/sysctl.conf, comment out the line that sets kern.ipc.maxsockbuf, and reboot the computer.

OR

If you have no other Customization other than the one set by the Broadband Tuner application, rename or delete sysctl.conf.

Apple is aware of this problem, and has opened Bug ID: 15542576.

WebLaunch Issues With Safari

There is an issue with Weblaunch with Safari. The default security settings in the version of Safari that comes with OS X 10.9 (Mavericks) prevents AnyConnect Weblaunch from working. To configure Safari to allow Weblaunch, edit the URL of the ASA to Unsafe Mode, as described below.

  1. Open Safari > Preferences > Security > Manage Website Settings.

  2. Click on the ASA and select run in Unsafe Mode.

Active X Upgrade Can Disable Weblaunch

Automatic upgrades of AnyConnect software via WebLaunch will work with limited user accounts as long as there are no changes required for the ActiveX control.

Occasionally, the control will change due to either a security fix or the addition of new functionality.

Should the control require an upgrade when invoked from a limited user account, the administrator must deploy the control using the AnyConnect pre-installer, SMS, GPO or other administrative deployment methodology.

Internet Explorer, Java 7, and AnyConnect 3.1.1 Interoperability

Supported versions of Internet Explorer stop working when the user attempts to connect to the ASA, when Java 7 is installed on the endpoint, when HostScan is installed and enabled on the ASA, and when AnyConnect 3.1.1 is installed and enabled on the ASA.

This does not happen when Active X or earlier versions of Java 7 are installed. To avoid this, use a supported version of Java on the endpoint that is earlier than Java 7.

Refer to the Bug Toolkit and defect CSCuc48299 to verify.

Implicit DHCP filter applied when Tunnel All Networks Configured

To allow local DHCP traffic to flow in the clear when Tunnel All Networks is configured, AnyConnect adds a specific route to the local DHCP server when the AnyConnect client connects. To prevent data leakage on this route, AnyConnect also applies an implicit filter on the LAN adapter of the host machine, blocking all traffic for that route except DHCP traffic.

AnyConnect VPN over Tethered Devices

Cisco has qualified the AnyConnect VPN client over a bluetooth or USB tethered Apple iPhone only. Network connectivity provided by other tethered devices should be verified with the AnyConnect VPN client before deployment.

AnyConnect Smart Card Support

AnyConnect supports Smartcard provided credentials in the following environments:

  • Microsoft CAPI 1.0 and CAPI 2.0 on Windows7, Windows 8, and Windows 10.

  • Keychain on macOS.

    Note

    AnyConnect does not support Smart cards on Linux or PKCS #11 devices.


AnyConnect Virtual Testing Environment

Cisco performs a portion of AnyConnect client testing using these virtual machine environments:

  • VMWare ESXi Hypervisor (vSphere) 4.0.1 and later

  • VMWare Fusion 2.x, 3.x, and 4.x

We do not support running AnyConnect in virtual environments; however, we expect AnyConnect to function properly in the VMWare environments we test in.

If you encounter any issues with AnyConnect in your virtual environment, report them. We will make our best effort to resolve them.

UTF-8 Character Support for AnyConnect Passwords

AnyConnect 3.0 or later used with ASA 8.4(1) or later supports UTF-8 characters in passwords sent using RADIUS/MSCHAP and LDAP protocols.

Disabling Auto Update May Prevent Connectivity Due to a Version Conflict

When Auto Update is disabled for a client running AnyConnect, the ASA must have the same version of AnyConnect or earlier installed, or the client will fail to connect to the VPN.

To avoid this problem, configure the same version or earlier AnyConnect package on the ASA, or upgrade the client to the new version by enabling Auto Update.

Interoperability between Network Access Manager and other Connection Managers

When the Network Access Manager operates, it takes exclusive control over the network adapters and blocks attempts by other software connection managers (including the Windows native connection manager) to establish connections. Therefore, if you want AnyConnect users to use other connection managers on their endpoint computers (such as iPassConnect Mobility Manager), they must disable Network Access Manager either through the Disable Client option in the Network Access Manager GUI, or by stopping the Network Access Manager service.

Network Interface Card Drivers Incompatible with Network Access Manager

The Intel wireless network interface card driver, version 12.4.4.5, is incompatible with Network Access Manager. If this driver is installed on the same endpoint as the Network Access Manager, it can cause inconsistent network connectivity and an abrupt shutdown of the Windows operating system.

Avoiding SHA 2 Certificate Validation Failure (CSCtn59317)

The AnyConnect client relies on the Windows Cryptographic Service Provider (CSP) of the certificate for hashing and signing of data required during the IKEv2 authentication phase of the IPsec/IKEv2 VPN connection. If the CSP does not support SHA 2 algorithms, and the ASA is configured for the pseudo-random function (PRF) SHA256, SHA384, or SHA512, and the connection profile (tunnel-group) is configured for certificate or certificate and AAA authentication, certificate authentication fails. The user receives the message Certificate Validation Failure.

This failure occurs for Windows only, for certificates that belong to CSPs that do not support SHA 2-type algorithms. Other supported OSs do not experience this problem.

To avoid this problem you can configure the PRF in the IKEv2 policy on the ASA to md5 or sha (SHA 1). Alternatively, you can modify the certificate CSP value to native CSPs that work such as Microsoft Enhanced RSA and AES Cryptographic Provider. Do not apply this workaround to SmartCards certificates. You cannot change the CSP names. Instead, contact the SmartCard provider for an updated CSP that supports SHA 2 algorithms.


Caution

Performing the following workaround actions could corrupt the user certificate if you perform them incorrectly. Use extra caution when specifying changes to the certificate.


You can use the Microsoft Certutil.exe utility to modify the certificate CSP values. Certutil is a command-line utility for managing a Windows CA, and is available in the Microsoft Windows Server 2003 Administration Tools Pack. You can download the Tools Pack at this URL:

http://www.microsoft.com/downloads/en/details.aspx?FamilyID=c16ae515-c8f4-47ef-a1e4-a8dcbacff8e3&displaylang=en

Follow this procedure to run Certutil.exe and change the Certificate CSP values:

  1. Open a command window on the endpoint computer.

  2. View the certificates in the user store along with their current CSP value using the following command:certutil -store -user My

    The following example shows the certificate contents displayed by this command:
    
    ================ Certificate 0 ================
    Serial Number: 3b3be91200020000854b
    Issuer: CN=cert-issuer, OU=Boston Sales, O=Example Company, L=San Jose,
    S=CA, C=US, E=csmith@example.com
    NotBefore: 2/16/2011 10:18 AM
    NotAfter: 5/20/2024 8:34 AM
    Subject: CN=Carol Smith, OU=Sales Department, O=Example Company, L=San Jose, S=C
    A, C=US, E=csmith@example.com
    Non-root Certificate
    Template:
    Cert Hash(sha1): 86 27 37 1b e6 77 5f aa 8e ad e6 20 a3 14 73 b4 ee 7f 89 26
      Key Container = {F62E9BE8-B32F-4700-9199-67CCC86455FB}
      Unique container name: 46ab1403b52c6305cb226edd5276360f_c50140b9-ffef-4600-ada
    6-d09eb97a30f1
      Provider = Microsoft Enhanced RSA and AES Cryptographic Provider
    Signature test passed
    
  3. Identify the <CN> attribute in the certificate. In the example, the CN is Carol Smith. You need this information for the next step.

  4. Modify the certificate CSP using the following command. The example below uses the subject <CN> value to select the certificate to modify. You can also use other attributes.

    On Windows 7 or later, use this command: certutil -csp "Microsoft Enhanced RSA and AES Cryptographic Provider" -f -repairstore -user My <CN> carol smith

  5. Repeat step 2 and verify the new CSP value appears for the certificate.

Configuring Antivirus Applications for HostScan

Antivirus applications can misinterpret the behavior of some of the applications included in the posture module and the HostScan package as malicious. Before installing the posture module or HostScan package, configure your antivirus software to “white-list” or make security exceptions for these HostScan applications:

  • cscan.exe

  • ciscod.exe

  • cstub.exe

Microsoft Internet Explorer Proxy Not Supported by IKEv2

IKEv2 does not support the public-side Microsoft Internet Explorer proxy. If you need support for that feature, use SSL. Private-side proxies are supported by both IKEv2 and SSL as dictated by the configuration sent from the secure gateway. IKEv2 applies the proxy configuration sent from the gateway, and subsequent HTTP traffic is subject to that proxy configuration.

MTU Adjustment on Group Policy May Be Required for IKEv2

AnyConnect sometimes receives and drops packet fragments with some routers, resulting in a failure of some web traffic to pass.

To avoid this, lower the value of the MTU. We recommend 1200. The following example shows how to do this using CLI:


hostname# config t
hostname(config)# group-policy DfltGrpPolicy attributes
hostname(config-group-policy)# webvpn
hostname(config-group-webvpn)# anyconnect mtu 1200

To set the MTU using ASDM, go to Configuration > Network (Client) Access > Group Policies > Add or Edit > Advanced > SSL VPN Client.

MTU Automatically Adjusted When Using DTLS

If Dead Peer Detection (DPD) is enabled for DTLS, the client automatically determines the path MTU. If you previously reduced the MTU using the ASA, you should restore the setting to the default (1406). During tunnel establishment, the client auto-tunes the MTU using special DPD packets. If you still have a problem, use the MTU configuration on the ASA to restrict the MTU as before.

Network Access Manager and Group Policy

Windows Active Directory Wireless Group Policies manage the wireless settings and any wireless networks that are deployed to PCs in a specific Active Directory Domain. When installing the Network Access Manager, administrators must be aware that certain wireless Group Policy Objects (GPOs) can affect the behavior of the Network Access Manager. Administrators should test the GPO policy settings with the Network Access Manager before doing full GPO deployment. The following GPO conditions may prevent the Network Access Manager from operating as expected :
  • When using the Windows 7 or later,Only use Group Policy profiles for allowed networks option.

FreeRADIUS Configuration to Work With Network Access Manager

To use Network Access Manager, you may need to adjust the FreeRADIUS configuration. Any ECDH related ciphers are disabled by default to prevent vulnerability. In /etc/raddb/eap.conf, change the cipher_list value.

Full Authentication Required if Roaming between Access Points

A mobile endpoint running Windows 7 or later must do a full EAP authentication instead of leveraging the quicker PMKID reassociation when the client roams between access points on the same network. Consequently, in some cases, AnyConnect prompts the user to enter credentials for every full authentication if the active profile requires it.

User Guideline for Cisco Cloud Web Security Behavior with IPv6 Web Traffic

Unless an exception for an IPv6 address, domain name, address range, or wild card is specified, IPv6 web traffic is sent to the scanning proxy where it performs a DNS lookup to see if there is an IPv4 address for the URL the user is trying to reach. If the scanning proxy finds an IPv4 address, it uses that for the connection. If it does not find an IPv4 address, the connection is dropped.

If you want all IPv6 traffic to bypass the scanning proxies, you can add this static exception for all IPv6 traffic: /0. Doing this makes all IPv6 traffic bypass all scanning proxies. This means that IPv6 traffic is not protected by Cisco Cloud Web Security.

Preventing Other Devices in a LAN from Displaying Hostnames

After one uses AnyConnect to establish a VPN session with Windows 7 or later on a remote LAN, the network browsers on the other devices in the user’s LAN display the names of hosts on the protected remote network. However, the other devices cannot access these hosts.

To ensure the AnyConnect host prevents the hostname leak between subnets, including the name of the AnyConnect endpoint host, configure that endpoint to never become the master or backup browser.

  1. Enter regedit in the Search Programs and Files text box.

  2. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Browser\Parameters\

  3. Double-click MaintainServerList.

The Edit String window opens.

  1. Enter No.

  2. Click OK.

  3. Close the Registry Editor window.

Revocation Message

An AnyConnect certificate revocation warning popup window opens after authentication if AnyConnect attempts to verify a server certificate that specifies the distribution point of an LDAP certificate revocation list (CRL) if the distribution point is only internally accessible.

If you want to avoid the display of this popup window, do one of the following:

  • Obtain a certificate without any private CRL requirements.

  • Disable server certificate revocation checking in Internet Explorer.


    Caution

    Disabling server certificate revocation checking in Internet Explorer can have severe security ramifications for other uses of the OS.


Messages in the Localization File Can Span More than One Line

If you try to search for messages in the localization file, they can span more than one line, as shown in the example below:


msgid ""
"The service provider in your current location is restricting access to the "
"Secure Gateway. "

AnyConnect for Mac OS X Performance when Behind Certain Routers

When the AnyConnect client for Mac OS X attempts to create an SSL connection to a gateway running IOS, or when the AnyConnect client attempts to create an IPsec connection to an ASA from behind certain types of routers (such as the Cisco Virtual Office (CVO) router), some web traffic may pass through the connection while other traffic drops. AnyConnect may calculate the MTU incorrectly.

To work around this problem, manually set the MTU for the AnyConnect adaptor to a lower value using the following command from the Mac OS X command line:

sudo ifconfig utun0 mtu 1200 (For Mac OS X v10.7 and later)

Preventing Windows Users from Circumventing Always-on

On Windows computers, users with limited or standard privileges may sometimes have write access to their program data folders. This could allow them to delete the AnyConnect profile file and thereby circumvent the always-on feature. To prevent this, configure the computer to restrict access to the C:\ProgramData folder, or at least the Cisco sub-folder.

Avoid Wireless-Hosted-Network

Using the Windows 7 or later Wireless Hosted Network feature can make AnyConnect unstable. When using AnyConnect, we do not recommend enabling this feature or running front-end applications that enable it (such as Connectify or Virtual Router).

AnyConnect Requires That the ASA Be Configured to Accept TLSv1 Traffic

AnyConnect requires the ASA to accept TLSv1 traffic, but not SSLv3 traffic. The SSLv3 key derivation algorithm uses MD5 and SHA-1 in a way that can weaken the key derivation. TLSv1, the successor to SSLv3, resolves this and other security issues present in SSLv3.

Thus, the AnyConnect client cannot establish a connection with the following ASA settings for “ssl server-version”:

ssl server-version sslv3

ssl server-version sslv3-only

Trend Micro Conflicts with Install

If you have Trend Micro on your device, the Network Access Manager will not install because of a driver conflict. You can uninstall the Trend Micro or uncheck trend micro common firewall driver to bypass the issue.

What HostScan Reports

None of the supported antimalware and firewall products report the last scan time information. HostScan reports the following:

  • For antimalware

    • Product description

    • Product version

    • File system protection status (active scan)

    • Data file time (last update and timestamp)

  • For firewall

    • Product description

    • Product version

    • Is firewall enabled

Long Reconnects (CSCtx35606)

You may experience long reconnects on Windows if IPv6 is enabled and auto-discovery of proxy setting is either enabled in Internet Explorer or not supported by the current network environment. As a workaround, you can disconnect any physical network adapters not used for VPN connection or disable proxy auto-discovery in IE, if proxy auto-discovery is not supported by the current network environment. With release 3.1.03103, those with multi-homed systems may also experience the long reconnects.

Users with Limited Privileges Cannot Upgrade ActiveX

On Windows 7 or later, user accounts with limited privileges cannot upgrade ActiveX controls and therefore cannot upgrade the AnyConnect client with the web deploy method. For the most secure option, Cisco recommends that users upgrade the client from within the application by connecting to the headend and upgrading.


Note

If the ActiveX control was previously installed on the client using the administrator account, the user can upgrade the ActiveX control.


Using the Manual Install Option on Mac OS X if the Java Installer Fails

If users WebLaunch from the ASA headend to start AnyConnect on a Mac, and the Java installer fails, a dialog box presents a Manual Install link. Users should do the following when this happens:

  1. Click Manual Install. A dialog box presents the option to save a .dmg file that contains an OS X installer.

  2. Mount the disk image (.dmg) file by opening it and browsing to the mounted volume using Finder.

  3. Open a Terminal window and use the CD command to navigate to the directory containing the file saved. Open the .dmg file and run the installer.

  4. Following the installation, choose Applications > Cisco > Cisco AnyConnect Secure Mobility Client to initiate an AnyConnect session, or use Launchpad.

No Pro-Active Key Caching (PKC) or CCKM Support

Network Access Manager does not support PKC or CCKM caching. On Windows 7, fast roaming with a non-Cisco wireless card is unavailable.

Application Programming Interface for the AnyConnect Secure Mobility Client

The AnyConnect Secure Mobility Client includes an Application Programming Interface (API) for those who want to write their own client programs.

The API package contains documentation, source files, and library files to support a C++ interface for the Cisco AnyConnect VPN Client. You can use the libraries and example programs for building on Windows, Linux and MAC platforms. The Makefiles (or project files) for the Windows platform are also included. For other platforms, it includes platform specific scripts showing how to compile the example code. Network administrators can link their application (GUI, CLI, or embedded application) with these files and libraries.

You can download the APIs from Cisco.com.

For support issues regarding the AnyConnect API, send e-mail to the following address: anyconnect-api-support@cisco.com.
