Cisco Identity Services Engine Database Default Credentials Vulnerability

Advisory ID: cisco-sa-20110920-ise

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20110920-ise

Revision 1.2

Last Updated  2012 March 22 18:24  UTC (GMT)

For Public Release 2011 September 20 16:00  UTC (GMT)


Summary

Cisco Identity Services Engine (ISE) contains a set of default credentials for its underlying database. A remote attacker could use those credentials to modify the device configuration and settings or gain complete administrative control of the device.

Cisco has released free software updates that address this vulnerability. There is no workaround for this vulnerability.

This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20110920-ise.

Affected Products

Vulnerable Products

This vulnerability affects all releases of Cisco ISE prior to release 1.0.4.MR2. This applies to both the hardware appliance and the software-only versions of the product.

The following methods can be used to determine which Cisco ISE release is installed:

  • From the Cisco ISE command-line interface (CLI), issue the show application version ise command, as shown in the following example:
    ise-node1/admin# show application version ise
    
    Cisco Identity Services Engine
    ---------------------------------------------
    Version      : 1.0.4.558
    Build Date   : Thu 18 Aug 2011 04:41:15 PM EST
    Install Date : Fri 16 Sep 2011 01:38:48 PM EST  
    
    
    ise-node1/admin#
    Based on the output of the show application version ise on the previous example, the installed Cisco ISE release is 1.0.4.588.
  • On the main login page of the Cisco ISE web-based interface, the version information is displayed under the "Identity Services Engine" heading.
  • From the Cisco ISE web-based interface, log in and click on the "Help" button located at the bottom left corner of the screen. From the resulting menu, select "About Identity Services Engine". Version information is displayed on the resulting window under the "Identity Services Engine" heading.

Products Confirmed Not Vulnerable

No other Cisco products are currently known to be affected by this vulnerability.

Details

The Cisco Identity Services Engine provides an attribute-based access control solution that combines authentication, authorization, and accounting (AAA); posture; profiling; and guest management services on a single platform. Administrators can centrally create and manage access control policies for users and endpoints in a consistent fashion, and gain end-to-end visibility into everything that is connected to the network.

The Cisco ISE contains a set of default credentials for its underlying database. A remote attacker could use those credentials to modify the device configuration and settings or gain complete administrative control of the device.

This vulnerability is documented in Cisco bug ID CSCts59135 ( registered customers only) and has been assigned the CVE identifier CVE-2011-3290.

Vulnerability Scoring Details

Cisco has provided scores for the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0.

CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response.

Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks.

Cisco has provided an FAQ to answer additional questions regarding CVSS at

http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html .

Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at

Software Versions and Fixes

When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.

In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.

Cisco ISE release 1.0.4.573 is available as either an ISO image containing a complete installation image, which can be used for a new install or for completely reimaging an existing installation (filename is ise-1.0.4.573.i386.iso), or as an application bundle that can be used to upgrade an existing Cisco ISE release 1.0 (1.0.3.377) or Cisco ISE release 1.0MR (1.0.4.558) installation to Cisco ISE release 1.0.4.573 (filename is ise-appbundle-1.0.4.573.i386.tar.gz).

Those files can be downloaded from the Software Center on Cisco.com by visiting http://www.cisco.com/cisco/software/navigator.html leavingcisco.com. The files are accessible using the following path:

Products > Security > Identity Management > Cisco Identity Services Engine > Cisco Identity Services Engine Software 1.0 > Identity Services Engine System Software-1.0 MR

On installation, either as a clean install from the ISO image or application bundle for upgrading an existing install, Cisco ISE release 1.0.4.573 will:

  • remove the existing database default credentials, and
  • request the user to provide new database credentials

Workarounds

There is no workaround for this vulnerability.

Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Intelligence companion document for this advisory: http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20110920-ise

Obtaining Fixed Software

Cisco has released free software updates that address this vulnerability. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment.

Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html , or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml .

Do not contact psirt@cisco.com or security-alert@cisco.com for software upgrades.

Customers with Service Contracts

Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com.

Customers using Third Party Support Organizations

Customers whose Cisco products are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory.

The effectiveness of any workaround or fix is dependent on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed.

Customers without Service Contracts

Customers who purchase direct from Cisco but do not hold a Cisco service contract, and customers who purchase through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows.

  • +1 800 553 2447 (toll free from within North America)
  • +1 408 526 7209 (toll call from anywhere in the world)
  • e-mail: tac@cisco.com

Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC.
