Caveats Resolved in Release 12.2(33)SXH7

Resolved AAA Caveats

Symptoms: The Cisco IOS software image may unexpectedly restart when a crafted “msg-auth-response-get-user” TACACS+ packet is received.

Conditions: This symptom is observed after the Cisco platform had send an initial “recv-auth-start” TACACS+ packet.

Workaround: There is no workaround.

Resolved Multicast Caveats

Symptoms: A router may reload after reporting SYS-3-OVERRUN or SYS-3-BADBLOCK error messages. SYS-2-GETBUF with ‘Bad getbuffer’ error may also be reported.

Condition: Occurs when PIM auto-RP is configured and IP multicast boundary is enabled with the filter-autorp option.

Workaround: Configure IP multicast boundary without the filter-autorp option.

Symptom: A Cisco IOS device may experience an unexpected reload as a result of mtrace packet processing.

Conditions:

Workaround: None other than avoiding the use of mtrace functionality.

Resolved Security Caveats

Symptoms: A Cisco router that is running Cisco IOS Release 12.4(25) may crash due to SSH.

Conditions: This symptom occurs when SSH is enabled on the router. An attempt to access the router via SSH is made.

Workaround: Do not use SSH. Disable SSH on the router by removing the RSA keys:

“crypto key zeroize rsa”

Further Problem Description: This issue has not been seen in Cisco IOS Release 12.4(23) and earlier releases. It also has not been seen in Cisco IOS Release 12.4T images.

Symptoms: Malformed SSH version 2 packets may cause a memory leak.

Conditions: This symptom is observed on a Cisco platform configured for SSH version 2 after it has received malformed SSHv2 packets. The impact of this flaw is that the affected platform may operate in a degraded condition. Under rare circumstances it may reload to recover itself.

Workarounds: Options consist of using SSH version 1 in the interim until the affected platform can be upgraded to a fixed release or permitting only known trusted hosts/networks that can connect to the router by using a VTY access list.

Following are examples of the workarounds:

Configure SSH version 1

Configure SSH version 1
+----------------------
!-- configure from global config mode
!
config t
!
ip ssh version 1
end
 
VTY access-list
+--------------
!-- 10.1.1.0/24 is a trusted network that
!-- is permitted access to the router, all
!-- other access is denied
!
access-list 99 permit 10.1.1.0 0.0.0.255
access-list 99 deny any
!
line vty 0 4
access-class 99 in
end
 

More information about configuring VTY access lists is available in Cisco IOS Security Configuration Guide: Securing the Data Plane, Release 12.4T Controlling Access to a Virtual Terminal Line:

http://www.cisco.com/en/US/docs/ios-xml/ios/sec_data_acl/configuration/12-4t/sec-cntrl-acc-vtl.html

More information about SSH on IOS is available in the Configuring Secure Shell on Routers and Switches Running Cisco IOS guide:

http://www.cisco.com/en/US/tech/tk583/tk617/technologies_tech_note09186a00800949e2.shtml

Resolved Unknown Caveats

Symptom: 6500 may experience redzone crash at UDLD process. Message may appear %SYS-SP-3-OVERRUN: Block overrun at 44456570 (red zone 6D000700) -Traceback= 40291448 402938DC 40D74570 40D763A0

Traceback will vary from code to code.

Conditions: UDLD configured

Workaround: Disable UDLD.

Symptoms: Upgrade from 12.2(18)SXF6 to 12.2(33)SXH5 introduced additional vty lines to the running-configuration (vtp line 5 - 15). These new lines do not inherit the security ACL or transports configured by the customer on the old lines (0-4). Switch upgrade caused device to be non-compliant with network security policy defined by customer.

Condition: Software upgrade from 12.2(18)SXF6 to 12.2(33)SXH5.

Workaround: We have to manually configure the ACL for those newly introduced vty lines.

Symptom: Currently in EARL7 system, For an IPv6 packet the 96 bytes cover DBUS header (22), Ether header (14), IPv6 harder (40), IPv6 extension headers, and L4 header. That means only 20 bytes (96 - 22 - 14 - 40) are for extension header(s) and L4 header. So even packet with small extension header(s) can use up to 20 bytes that would cause l4_hdr_vld = 0. When that happens, all L4 features cannot be applied and packet would be hardware forwarded based on L3 forwarding result.

Conditions: This issue is present from day one but would cause threat only when ipv6 access-list is configured on any interface and that access-list is containing L4 options.

Workaround: No Workaround

Conditions: When an ipv6 RACL is confiured on an interface. All packets containing ipv6 optional headers are punted to RP. But if any packets that are sent with no L4 header are also hitting this punt entry present at the top of tcam.

Workaround: No Workaround:

Symptoms: A Cat4k switch may reload after receiving a malformed packet on one specific specific port.

Conditions: This symptom may be observed on a Cat4k switch that enables DNSIX audit trail and recieves crafted IP packets on a specific port.

Workaround: Do not enable the DNSIX audit trail.

Resolved WAN Caveats

Symptom: Cisco IOS Software is affected by NTP mode 7 denial-of-service vulnerability. Note: The fix for this vulnerability has a behavior change affect on Cisco IOS Operations for Mode 7 packets. See the section Further Description of this release note enclosure.

Conditions: Cisco IOS Software with support for Network Time Protocol (NTP) contains a vulnerability processing specific NTP Control Mode 7 packets. This results in increased CPU on the device and increased traffic on the network segments.

This is the same as the vulnerability which is described in http://www.kb.cert.org/vuls/id/568372

Cisco has release a public facing vulnerability alert at the following link:

http://tools.cisco.com/security/center/viewAlert.x?alertId=19540

Cisco IOS Software that has support for NTPv4 is NOT affected. NTPv4 was introduced into Cisco IOS Software: 12.4(15)XZ, 12.4(20)MR, 12.4(20)T, 12.4(20)YA, 12.4(22)GC1, 12.4(22)MD, 12.4(22)YB, 12.4(22)YD, 12.4(22)YE and 15.0(1)M.

All other versions of Cisco IOS and Cisco IOS XE Software are affected.

To see if a device is configured with NTP, log into the device and issue the CLI command show running-config | include ntp . If the output returns either of the following commands listed then the device is vulnerable:

ntp master <any following commands>
ntp peer <any following commands>
ntp server <any following commands>
ntp broadcast client
ntp multicast client
 

The following example identifies a Cisco device that is configured with NTP:

router# show running-config | include ntp
ntp peer 192.168.0.12
router#
 

The following example identifies a Cisco device that is not configured with NTP:

router# show running-config | include ntp
router#
 

To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to “Cisco Internetwork Operating System Software” or “Cisco IOS Software.” The image name displays in parentheses, followed by “Version” and the Cisco IOS Software release name. Other Cisco devices do not have the show version command or may provide different output.

The following example identifies a Cisco product that is running Cisco IOS Software Release 12.3(26) with an installed image name of C2500-IS-L:

Router# show version

Workaround: There are no workarounds other than disabling NTP on the device. The following mitigations have been identified for this vulnerability; only packets destined for any configured IP address on the device can exploit this vulnerability. Transit traffic will not exploit this vulnerability.

Note: NTP peer authentication is not a workaround and is still a vulnerable configuration.

NTP Access Group

Warning: Because the feature in this vulnerability utilizes UDP as a transport, it is possible to spoof the sender’s IP address, which may defeat access control lists (ACLs) that permit communication to these ports from trusted IP addresses. Unicast Reverse Path Forwarding (Unicast RPF) should be considered to be used in conjunction to offer a better mitigation solution.

!--- Configure trusted peers for allowed access
access-list 1 permit 171.70.173.55
!--- Apply ACE to the NTP configuration
ntp access-group peer 1
 

For additional information on NTP access control groups, consult the document titled “Performing Basic System Management” at the following link:

http://www.cisco.com/en/US/docs/ios/netmgmt/configuration/guide/nm_basic_sys_manage.html#wp1034942

Infrastructure Access Control Lists

Warning: Because the feature in this vulnerability utilizes UDP as a transport, it is possible to spoof the sender’s IP address, which may defeat ACLs that permit communication to these ports from trusted IP addresses. Unicast RPF should be considered to be used in conjunction to offer a better mitigation solution.

Although it is often difficult to block traffic that transits a network, it is possible to identify traffic that should never be allowed to target infrastructure devices and block that traffic at the border of networks.

Infrastructure ACLs (iACLs) are a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The iACL example below should be included as part of the deployed infrastructure access-list, which will help protect all devices with IP addresses in the infrastructure IP address range:

!---
!--- Feature: Network Time Protocol (NTP)
!---
 
access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD
INFRASTRUCTURE_ADDRESSES WILDCARD eq 123
 
!--- Note: If the router is acting as a NTP broadcast client
!--- via the interface command "ntp broadcast client"
!--- then broadcast and directed broadcasts must be
!--- filtered as well. The following example covers
!--- an infrastructure address space of 192.168.0.X
 
access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD
host 192.168.0.255 eq ntp
access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD
host 255.255.255.255 eq ntp
 
!--- Note: If the router is acting as a NTP multicast client
!--- via the interface command "ntp multicast client"
!--- then multicast IP packets to the mutlicast group must
!--- be filtered as well. The following example covers
!--- a NTP multicast group of 239.0.0.1 (Default is
!--- 224.0.1.1)
 
access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD
host 239.0.0.1 eq ntp
 
!--- Deny NTP traffic from all other sources destined
!--- to infrastructure addresses.
 
access-list 150 deny udp any
INFRASTRUCTURE_ADDRESSES WILDCARD eq 123
 
!--- Permit/deny all other Layer 3 and Layer 4 traffic in
!--- accordance with existing security policies and
!--- configurations. Permit all other traffic to transit the
!--- device.
 
access-list 150 permit ip any any
 
!--- Apply access-list to all interfaces (only one example
!--- shown)
 
interface fastEthernet 2/0
ip access-group 150 in

Control Plane Policing

Provided under Control Plane Policing there are two examples. The first aims at preventing the injection of malicious traffic from untrusted sources, whilst the second looks at rate limiting NTP traffic to the box.

—Filtering untrusted sources to the device.

Warning: Because the feature in this vulnerability utilizes UDP as a transport, it is possible to spoof the sender’s IP address, which may defeat ACLs that permit communication to these ports from trusted IP addresses. Unicast RPF should be considered to be used in conjunction to offer a better mitigation solution.

Control Plane Policing (CoPP) can be used to block untrusted UDP traffic to the device. Cisco IOS software releases 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T support the CoPP feature. CoPP can be configured on a device to help protect the management and control planes and minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic that is sent to infrastructure devices in accordance with existing security policies and configurations. The CoPP example below should be included as part of the deployed CoPP, which will help protect all devices with IP addresses in the infrastructure IP address range.

!--- Feature: Network Time Protocol (NTP)
 
access-list 150 deny udp TRUSTED_SOURCE_ADDRESSES WILDCARD
any eq 123
 
!--- Deny NTP traffic from all other sources destined
!--- to the device control plane.
 
access-list 150 permit udp any any eq 123
 
!--- Permit (Police or Drop)/Deny (Allow) all other Layer3 and
!--- Layer4 traffic in accordance with existing security policies
!--- and configurations for traffic that is authorized to be sent
!--- to infrastructure devices
!--- Create a Class-Map for traffic to be policed by
!--- the CoPP feature
 
class-map match-all drop-udp-class
match access-group 150
 
!--- Create a Policy-Map that will be applied to the
!--- Control-Plane of the device.
 
policy-map drop-udp-traffic
class drop-udp-class
drop
 
!--- Apply the Policy-Map to the
!--- Control-Plane of the device
 
control-plane
service-policy input drop-udp-traffic
 

In the above CoPP example, the access control list entries (ACEs) that match the potential exploit packets with the “permit” action result in these packets being discarded by the policy-map “drop” function, while packets that match the “deny” action (not shown) are not affected by the policy-map drop function.

—Rate Limiting the traffic to the device The CoPP example below could be included as part of the deployed CoPP, which will help protect targeted devices from processing large amounts of NTP traffic.

Warning: If the rate-limits are exceeded valid NTP traffic may also be dropped.

!--- Feature: Network Time Protocol (NTP)
 
access-list 150 permit udp any any eq 123
 
!--- Create a Class-Map for traffic to be policed by
!--- the CoPP feature
 
class-map match-all rate-udp-class
match access-group 150
 
!--- Create a Policy-Map that will be applied to the
!--- Control-Plane of the device.
!--- NOTE: See section "4. Tuning the CoPP Policy" of
!--- http://www.cisco.com/web/about/security/intelligence/coppwp_gs.html#5
!--- for more information on choosing the most
!--- appropriate traffic rates
 
policy-map rate-udp-traffic
class rate-udp-class

!--- Apply the Policy-Map to the
!--- Control-Plane of the device
 
control-plane
service-policy input drop-udp-traffic
 

Additional information on the configuration and use of the CoPP feature can be found in the documents, “Control Plane Policing Implementation Best Practices” and “Cisco IOS Software Releases 12.2 S - Control Plane Policing” at the following links:

http://www.cisco.com/web/about/security/intelligence/coppwp_gs.html

Further Description: Cisco IOS Software releases that have the fix for this Cisco bug ID, have a behavior change for mode 7 private mode packets.

Cisco IOS Software release with the fix for this Cisco bug ID, will not process NTP mode 7 packets, and will display a message “NTP: Receive: dropping message: Received NTP private mode packet. 7” if debugs for NTP are enabled.

To have Cisco IOS Software process mode 7 packets, the CLI command ntp allow mode private should be configured. This is disabled by default.

Caveats Resolved in Release 12.2(33)SXH6

Resolved MPLS Caveats

A device running Cisco IOS Software, Cisco IOS XE Software, or Cisco IOS XR Software is vulnerable to a remote denial of service condition if it is configured for Multiprotocol Label Switching (MPLS) and has support for Label Distribution Protocol (LDP).

A crafted LDP UDP packet can cause an affected device running Cisco IOS Software or Cisco IOS XE Software to reload. On devices running affected versions of Cisco IOS XR Software, such packets can cause the device to restart the mpls_ldp process.

A system is vulnerable if configured with either LDP or Tag Distribution Protocol (TDP).

Cisco has released free software updates that address this vulnerability.

Workarounds that mitigate this vulnerability are available.

This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20100324-ldp.shtml

Resolved Routing Caveats

Symptoms: Cisco IOS device may crash.

Conditions: A Cisco IOS device may crash upon receiving a malformed OSPF message.

Before the issue can be triggered, the Cisco IOS device must be able to establish adjacency with an OSPF peer. The issue will then occur when the processing an OSPF message sent by the peer.

Workaround: There is no workaround. Using OSPF authentication can reduce/minimize the chance of hitting this issue.

Resolved Security Caveats

Cisco devices running affected versions of Cisco IOS Software are vulnerable to a denial of service (DoS) attack if configured for IP tunnels and Cisco Express Forwarding.

Cisco has released free software updates that address this vulnerability.

This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20090923-tunnels

Resolved Unknown Caveats

Cisco IOS devices that are configured for Internet Key Exchange (IKE) protocol and certificate based authentication are vulnerable to a resource exhaustion attack. Successful exploitation of this vulnerability may result in the allocation of all available Phase 1 security associations (SA) and prevent the establishment of new IPsec sessions.

Cisco has released free software updates that address this vulnerability.

This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20090923-ipsec

Cisco IOS Software configured with Authentication Proxy for HTTP(S), Web Authentication or the consent feature, contains a vulnerability that may allow an unauthenticated session to bypass the authentication proxy server or bypass the consent webpage.

There are no workarounds that mitigate this vulnerability.

Resolved IPServices Caveats

Several features within Cisco IOS Software are affected by a crafted UDP packet vulnerability. If any of the affected features are enabled, a successful attack will result in a blocked input queue on the inbound interface. Only crafted UDP packets destined for the device could result in the interface being blocked, transit traffic will not block the interface.

Cisco has released free software updates that address this vulnerability.

Workarounds that mitigate this vulnerability are available in the workarounds section of the advisory.

This advisory is posted at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20090325-udp

A vulnerability in the handling of IP sockets can cause devices to be vulnerable to a denial of service attack when any of several features of Cisco IOS Software are enabled. A sequence of specially crafted TCP/IP packets could cause any of the following results:

The configured feature may stop accepting new connections or sessions.

The memory of the device may be consumed.

The device may experience prolonged high CPU utilization.

The device may reload.

Cisco has released free software updates that address this vulnerability.

Workarounds that mitigate this vulnerability are available in the “workarounds” section of the advisory.

The advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20090325-ip

Symptom: An IOS software crash may occur when receiving a specific malformed DHCP packet.

Conditions: An IOS device configured for DHCP Server and receives a DHCP-request from a DHCP relay device. A specific malformed option in the packet packet may induce a software traceback or crash. The specific packet will not occur without manual modification.

Workaround: None.

Multiple Cisco products are affected by denial of service (DoS) vulnerabilities that manipulate the state of Transmission Control Protocol (TCP) connections. By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely. If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted. In some cases, a system reboot may be necessary to recover normal system operation. To exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with a vulnerable system.

In addition to these vulnerabilities, Cisco Nexus 5000 devices contain a TCP DoS vulnerability that may result in a system crash. This additional vulnerability was found as a result of testing the TCP state manipulation vulnerabilities.

Cisco has released free software updates for download from the Cisco website that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20090908-tcp24 .

Symptom: High CPU utilization after receives a ARP packet with protocol type as 0x1000.

Conditions: This problem occurs on SUP32 running 12.2(33)SXI. This problem does not occur on SUP720. The problem is only seen when you have bridge-group CLI being used which lead to arp pkts with protocol types as 0x1000 being bridged. The problem does not apply for IP ARP packets.

Workaround: Filter the ARP packet. The device Config should have bridge-group creation first; followed by interface specific bridge-group options.

Additional Information: This problem is now isolated to command ordering in the startup-config file. The bridge <> command is saved before the bridge-group <> command (which is run in the interface-config mode) is saved. The linking of IDB to bridge structure is not happening correctly and some check fails in the bridge code that lets the packet to be processed again and again instead of being dropped.

If the bridge-group <> command is removed in the startup-config and only applied after the bridge <> command is run, the problem will go away. Please use this workaround until a fix is put in.

Cisco IOS Software contains a vulnerability in multiple features that could allow an attacker to cause a denial of service (DoS) condition on the affected device. A sequence of specially crafted TCP packets can cause the vulnerable device to reload.

Cisco has released free software updates that address this vulnerability.

Several mitigation strategies are outlined in the workarounds section of this advisory.

This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20090325-tcp

Resolved LAN Caveats

Summary: Cisco’s VTP protocol implementation in some versions of Cisco IOS and CatOS may be vulnerable to a DoS attack via a specially crafted VTP packet sent from the local network segment when operating in either server or client VTP mode. When the device receives the specially crafted VTP packet, the switch may crash (and reload/hang). The crafted packet must be received on a switch interface configured to operate as a trunk port.

Workarounds: There are no workarounds available for this vulnerability.

This response is posted at http://tools.cisco.com/security/center/content/CiscoSecurityResponse/cisco-sr-20081105-vtp

Resolved Multicast Caveats

Symptom: MSFC crashes with RedZone memory corruption.

Conditions: This problem is seen when processing an Auto-RP packet and NAT is enabled.

Workaround: None known at this time.

Symptoms: PIM packets may be processed on interfaces which PIM is not explicitly configured.

Conditions: Unknown at this time.

Workarounds: Create an ACL to drop PIM packets to such interfaces.

Resolved Routing Caveats

Symptom: A Cisco IOS device that receives a BGP update message and as a result of AS prepending needs to send an update downstream that would have over 255 AS hops will send an invalid formatted update. This update when received by a downstream BGP speaker triggers a NOTIFICATION back to the sender which results in the BGP session being reset.

Conditions: This problem is seen when a Cisco IOS device receives a BGP update and due to a combination of either inbound, outbound, or both AS prepending it needs to send an update downstream that has more than 255 AS hops.

Workaround: The workaround is to implement bgp maxas-limit X on the device that after prepending would need to send an update with over 255 AS hops. Since IOS limits the route-map prepending value to 10 the most that could be added is 21 AS hops (10 on ingress, 10 on egress, and 1 for normal eBGP AS hop addition). Therefore, a conservative value to configure would be 200 to prevent this condition.

Caveats Resolved in Release 12.2(33)SXH4

Resolved Infrastructure Caveats

Symptom: The Cisco IOS HTTP server and the Cisco IOS HTTPS server provide web server functionality to be used by other Cisco IOS features that require it to function. For example, embedded device managers available for some Cisco IOS devices need the Cisco IOS HTTP server or the Cisco IOS HTTPS server to be enabled as a prerequisite.

One of the functionalities provided by the Cisco IOS HTTP server and the Cisco IOS HTTPS server is the WEB_EXEC module, which is the HTTP-based IOS EXEC Server. The WEB_EXEC module allows for both “show” and “configure” commands to be executed on the device through requests sent over the HTTP protocol.

Both the Cisco IOS HTTP server and the Cisco IOS HTTPS server use the locally configured enable password (configured by using the enable password or enable secret commands) as the default authentication mechanism for any request received. Other mechanisms can also be configured to authenticate requests to the HTTP or HTTPS interface. Some of those mechanisms are the local user database, an external RADIUS server or an external TACACS+ server.

If an enable password is not present in the device configuration, and no other mechanism has been configured to authenticate requests to the HTTP interface, the Cisco IOS HTTP server and the Cisco IOS HTTPS server may execute any command received without requiring authentication. Any commands up to and including commands that require privilege level 15 might then be executed on the device. Privilege level 15 is the highest privilege level on Cisco IOS devices.

Conditions: For a Cisco IOS device to be affected by this issue all of the following conditions must be met:

An enable password is not present in the device configuration

Either the Cisco IOS HTTP server or the Cisco IOS HTTPS server is enabled

No other authentication mechanism has been configured for access to the Cisco IOS HTTP server or Cisco IOS HTTPS server. Such mechanisms might include the local user database, RADIUS (Remote Authentication Dial In User Service), or TACACS+ (Terminal Access Controller Access-Control System)

The Cisco IOS HTTP server is enabled by default on some Cisco IOS releases.

Workaround: Any of the following workarounds can be implemented:

Enabling authentication of requests to the Cisco IOS HTTP Server or the Cisco IOS HTTPS server by configuring an enable password

Customers requiring the functionality provided by the Cisco IOS HTTP server or the Cisco IOS HTTPS server must configure an authentication mechanism for any requests received. One option is to use the enable password or enable secret commands to configure an enable password. The enable password is the default authentication mechanism used by both the Cisco IOS HTTP server and the Cisco IOS HTTPS server if no other method has been configured.

In order to configure an enable password by using the enable secret command, add the following line to the device configuration:

enable secret mypassword

Replace mypassword with a strong password of your choosing. For guidance on selecting strong passwords, please refer to your site security policy. The document entitled “Cisco IOS Password Encryption Facts” explains the differences between using the enable secret and the enable password commands to configure an enable password. This document is available at the following link: http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a00809d38a7.shtml

Enabling authentication of requests to the Cisco IOS HTTP Server or the Cisco IOS HTTPS server by configuring an authentication mechanism other than the default

Configure an authentication mechanism for access to the Cisco IOS HTTP server or the Cisco IOS HTTPS server other than the default. Such authentication mechanism can be the local user database, an external RADIUS server, an external TACACS+ server or a previously defined AAA (Authentication, Authorization and Accounting) method. As the procedure to enable an authentication mechanism for the Cisco IOS HTTP server and the Cisco IOS HTTPS server varies across Cisco IOS releases and considering other additional factors, no example will be provided. Customers looking for information about how to configure an authentication mechanism for the Cisco IOS HTTP server and for the Cisco IOS HTTPS server are encouraged to read the document entitled “AAA Control of the IOS HTTP Server”, which is available at the following link: http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a008069bdc5.shtml

Disabling the Cisco IOS HTTP Server and/or the Cisco IOS HTTPS server functionality

Customers who do not require the functionality provided by the Cisco IOS HTTP server or the Cisco IOS HTTPS server can disable it by adding the following commands to the device configuration:

no ip http server no ip http secure-server

The second command might return an error message if the Cisco IOS version installed and running on the device does not support the HTTPS server feature. This error message is harmless and can safely be ignored.

Please be aware that disabling the Cisco IOS HTTP server or the Cisco IOS HTTPS server may impact other features that rely on it. As an example, disabling the Cisco IOS HTTP server or the Cisco IOS HTTPS server will disable access to any embedded device manager installed on the device.

Further Problem Description: In addition to the explicit workarounds detailed above it is highly recommended that customers limit access to Cisco IOS HTTP server and the Cisco IOS HTTPS server to only trusted management hosts. Information on how to restrict access to the Cisco IOS HTTP server and the Cisco IOS HTTPS server based on IP addresses is available at the following link: http://www.cisco.com/en/US/docs/ios-xml/ios/https/configuration/12-4/nm-http-web.html#GUID-BB57C0D5-71DB-47C5-9C11-8146773D1127

Customers are also advised to review the “Management Plane” section of the document entitled “Cisco Guide to Harden Cisco IOS Devices” for additional recommendations to secure management connections to Cisco IOS devices. This document is available at the following link: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080120f48.shtml

Caveats Resolved in Release 12.2(33)SXH3a

Resolved Infrastructure Caveats

Symptom: The Cisco IOS HTTP server and the Cisco IOS HTTPS server provide web server functionality to be used by other Cisco IOS features that require it to function. For example, embedded device managers available for some Cisco IOS devices need the Cisco IOS HTTP server or the Cisco IOS HTTPS server to be enabled as a prerequisite.

One of the functionalities provided by the Cisco IOS HTTP server and the Cisco IOS HTTPS server is the WEB_EXEC module, which is the HTTP-based IOS EXEC Server. The WEB_EXEC module allows for both “show” and “configure” commands to be executed on the device through requests sent over the HTTP protocol.

Both the Cisco IOS HTTP server and the Cisco IOS HTTPS server use the locally configured enable password (configured by using the enable password or enable secret commands) as the default authentication mechanism for any request received. Other mechanisms can also be configured to authenticate requests to the HTTP or HTTPS interface. Some of those mechanisms are the local user database, an external RADIUS server or an external TACACS+ server.

If an enable password is not present in the device configuration, and no other mechanism has been configured to authenticate requests to the HTTP interface, the Cisco IOS HTTP server and the Cisco IOS HTTPS server may execute any command received without requiring authentication. Any commands up to and including commands that require privilege level 15 might then be executed on the device. Privilege level 15 is the highest privilege level on Cisco IOS devices.

Conditions: For a Cisco IOS device to be affected by this issue all of the following conditions must be met:

An enable password is not present in the device configuration

Either the Cisco IOS HTTP server or the Cisco IOS HTTPS server is enabled

No other authentication mechanism has been configured for access to the Cisco IOS HTTP server or Cisco IOS HTTPS server. Such mechanisms might include the local user database, RADIUS (Remote Authentication Dial In User Service), or TACACS+ (Terminal Access Controller Access-Control System)

The Cisco IOS HTTP server is enabled by default on some Cisco IOS releases.

Workaround: Any of the following workarounds can be implemented:

Enabling authentication of requests to the Cisco IOS HTTP Server or the Cisco IOS HTTPS server by configuring an enable password

Customers requiring the functionality provided by the Cisco IOS HTTP server or the Cisco IOS HTTPS server must configure an authentication mechanism for any requests received. One option is to use the enable password or enable secret commands to configure an enable password. The enable password is the default authentication mechanism used by both the Cisco IOS HTTP server and the Cisco IOS HTTPS server if no other method has been configured.

In order to configure an enable password by using the enable secret command, add the following line to the device configuration:

enable secret mypassword

Replace mypassword with a strong password of your choosing. For guidance on selecting strong passwords, please refer to your site security policy. The document entitled “Cisco IOS Password Encryption Facts” explains the differences between using the enable secret and the enable password commands to configure an enable password. This document is available at the following link: http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a00809d38a7.shtml

Enabling authentication of requests to the Cisco IOS HTTP Server or the Cisco IOS HTTPS server by configuring an authentication mechanism other than the default

Configure an authentication mechanism for access to the Cisco IOS HTTP server or the Cisco IOS HTTPS server other than the default. Such authentication mechanism can be the local user database, an external RADIUS server, an external TACACS+ server or a previously defined AAA (Authentication, Authorization and Accounting) method. As the procedure to enable an authentication mechanism for the Cisco IOS HTTP server and the Cisco IOS HTTPS server varies across Cisco IOS releases and considering other additional factors, no example will be provided. Customers looking for information about how to configure an authentication mechanism for the Cisco IOS HTTP server and for the Cisco IOS HTTPS server are encouraged to read the document entitled “AAA Control of the IOS HTTP Server”, which is available at the following link: http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a008069bdc5.shtml

Disabling the Cisco IOS HTTP Server and/or the Cisco IOS HTTPS server functionality

Customers who do not require the functionality provided by the Cisco IOS HTTP server or the Cisco IOS HTTPS server can disable it by adding the following commands to the device configuration:

no ip http server no ip http secure-server

The second command might return an error message if the Cisco IOS version installed and running on the device does not support the HTTPS server feature. This error message is harmless and can safely be ignored.

Please be aware that disabling the Cisco IOS HTTP server or the Cisco IOS HTTPS server may impact other features that rely on it. As an example, disabling the Cisco IOS HTTP server or the Cisco IOS HTTPS server will disable access to any embedded device manager installed on the device.

Further Problem Description: In addition to the explicit workarounds detailed above it is highly recommended that customers limit access to Cisco IOS HTTP server and the Cisco IOS HTTPS server to only trusted management hosts. Information on how to restrict access to the Cisco IOS HTTP server and the Cisco IOS HTTPS server based on IP addresses is available at the following link:

http://www.cisco.com/en/US/docs/ios-xml/ios/https/configuration/12-4/nm-http-web.html#GUID-BB57C0D5-71DB-47C5-9C11-8146773D1127

Customers are also advised to review the “Management Plane” section of the document entitled “Cisco Guide to Harden Cisco IOS Devices” for additional recommendations to secure management connections to Cisco IOS devices. This document is available at the following link: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080120f48.shtml

Other Resolved Caveats in Release 12.2(33)SXH3a

Routing

SXF15: IPv4/v6 BGP routes not cleared when source routes is gone

Caveats Resolved in Release 12.2(33)SXH3

Resolved IPServices Caveats

A router that has DHCP server enabled could reload after receiving a malformed UDP packet.

Workaround: None

Resolved Security Caveats

Symptoms: Devices running Cisco IOS may reload with the error message “System returned to ROM by abort at PC 0x0” when processing SSHv2 sessions. A switch crashes. We have a script running that will continuously ssh-v2 into the 3560 then close the session normally. If the vty line that is being used by SSHv2 sessions to the device is cleared while the SSH session is being processed, the next time an ssh into the device is done, the device will crash.

Conditions: This problem is platform independent, but it has been seen on Cisco Catalyst 3560, Cisco Catalyst 3750 and Cisco Catalyst 4948 series switches. The issue is specific to SSH version 2, and its seen only when the box is under brute force attack. This crash is not seen under normal conditions.

Workaround: There are mitigations to this vulnerability: For Cisco IOS, the SSH server can be disabled by applying the command crypto key zeroize rsa while in configuration mode. The SSH server is enabled automatically upon generating an RSA key pair. Zeroing the RSA keys is the only way to completely disable the SSH server.

Access to the SSH server on Cisco IOS may also be disabled via removing SSH as a valid transport protocol. This can be done by reapplying the transport input command with ‘ssh’ removed from the list of permitted transports on VTY lines while in configuration mode. For example: line vty 0 4 transport input telnet end

If SSH server functionality is desired, access to the server can be restricted to specific source IP addresses or blocked entirely using Access Control Lists (ACLs) on the VTY lines as shown in the following URL:

http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_9_ea1/configuration/guide/swacl.html

More information on configuring ACLs can be found on the Cisco public website: http://www.cisco.com/en/US/products/sw/secursw/ps1018/products_tech_note09186a00800a5b9a.shtml

Resolved Unknown Caveats

Cisco IOS Software Multi Protocol Label Switching (MPLS) Forwarding Infrastructure (MFI) is vulnerable to a Denial of Service (DoS) attack from specially crafted packets. Only the MFI is affected by this vulnerability. Older Label Forwarding Information Base (LFIB) implementation, which is replaced by MFI, is not affected.

Cisco has released free software updates that address this vulnerability.

Caveats Resolved in Release 12.2(33)SXH2

Resolved Security Caveats

A Cisco IOS device may crash while processing an SSL packet. This can happen during the termination of an SSL-based session. The offending packet is not malformed and is normally received as part of the packet exchange.

Cisco has released free software updates that address this vulnerability. Aside from disabling affected services, there are no available workarounds to mitigate an exploit of this vulnerability.

This advisory is posted at

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20080924-ssl .

Resolved Unknown Caveats

Symptoms: A device that is running Cisco IOS software may crash during processing of an Internet Key Exchange (IKE) message.

Conditions: The device must have a valid and complete configuration for IPsec. IPsec VPN features in Cisco IOS software that use IKE include Site-to- Site VPN tunnels, EzVPN (server and remote), DMVPN, IPsec over GRE, and GET VPN.

Workaround: Customers that do not require IPsec functionality on their devices can use the no crypto isakmp enable command in global configuration mode to disable the processing of IKE messages and eliminate device exposure.

If IPsec is configured, this bug may be mitigated by applying access control lists that limit the hosts or IP networks that are allowed to establish IPsec sessions with affected devices. This assumes that IPsec peers are known. This workaround may not be feasible for remote access VPN gateways where the source IP addresses of VPN clients are not known in advance. ISAKMP uses port UDP/500 and can also use UDP/848 (the GDOI port) when GDOI is in use.

Further Problem Description: This bug is triggered deep into the IKE negotiation, and an exchange of messages between IKE peers is necessary.

If IPsec is not configured, it is not possible to reach the point in the IKE negotiation where the bug exists.

Symptoms: Router reloads after authentication attempt fails on console.

Conditions: Occurs while performing AAA accounting. The accounting structure was freed twice, which results in crash. Occurs when the aaa accounting send stop-record authentication failure command is configured, which sends a stop record for authentication failure.

Workaround: Remove the aaa accounting send stop-record authentication failure command.

This is the Cisco Product Security Incident Response Team (PSIRT) response to a vulnerability that was reported on the Cisco NSP mailing list on August 17, 2007 regarding the crash and reload of devices running Cisco IOS after executing a command that uses, either directly or indirectly, a regular expression. The original post is available at the following link:

http://puck.nether.net/pipermail/cisco-nsp/2007-August/043002.html

The Cisco PSIRT posted a preliminary response on the same day and is available at the following link:

http://puck.nether.net/pipermail/cisco-nsp/2007-August/043010.html

Preliminary research pointed to a previously known issue that was documented as Cisco bug ID CSCsb08386 (registered customers only) , and entitled “PRP crash by show ip bgp regexp”, which was already resolved. Further research indicates that the current issue is a different but related vulnerability.

There are no workarounds available for this vulnerability. Cisco will update this document in the event of any changes.

Symptoms: Syslog displays password when copying the configuration via FTP.

Conditions: This symptom occurs when copying via FTP. The Syslog message displays the password given by the user as part of syntax of FTP copy.

Workaround: There is no workaround.

Resolved Routing Caveats

Symptoms: A few seconds after OSPF adjacencies come up, a router crashes because of a bus error.

Conditions: This symptom is observed on a Cisco router that functions as an ISR that is configured for OSPF.

Workaround: Add area 0 in the OSPF VRF processes.

Alternate Workaround: Enter the no capability transit command in the OSPF VRF processes.

Resolved Unknown Caveats

Symptom: Bus error crash (signal 10) seen after the following error message:

%MCAST-SP-6-GC_LIMIT_EXCEEDED: MLD snooping was trying to allocate more Layer 2 entries than what allowed (7744)
 

Conditions: This has been observed on a Catalyst6500 running IOS version 12.2(18)SXF1.

Workaround: A workaround exist to disable ipv6 mld snooping via the command no ipv6 mld snooping .

There is no negative impact of implementing the workaround as long as there is no IPV6 multicast traffic in the network.
