-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software Authentication Proxy Vulnerability Advisory ID: cisco-sa-20090923-auth-proxy Revision 1.0 For Public Release 2009 September 23 +--------------------------------------------------------------------- Summary ======= 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. Cisco has released free software updates that address this vulnerability. There are no workarounds that mitigate this vulnerability. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20090923-auth-proxy.shtml Note: The September 23, 2009, Cisco IOS Security Advisory bundled publication includes eleven Security Advisories. Ten of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses a vulnerability in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The following table lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 23, 2009, or earlier. http://www.cisco.com/warp/public/707/cisco-sa-20090923-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep09.html Affected Products ================= Vulnerable Products +------------------ Devices running affected versions of Cisco IOS Software and configured with Authentication Proxy for HTTP(S) or Web Authentication or the consent feature are vulnerable. 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 Cisco Internetwork Operating System Software IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright ©) 1986-2008 by cisco Systems, Inc. Compiled Mon 17-Mar-08 14:39 by dchih The following example shows a product that is running Cisco IOS Software release 12.4(20)T with an image name of C1841-ADVENTERPRISEK9-M: Router#show version Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright ©) 1986-2008 by Cisco Systems, Inc.

Products Confirmed Not Vulnerable +-------------------------------- The following products and features are not affected by this vulnerability: * Cisco IOS XR Software * Cisco IOS XE Software * Firewall Authentication Proxy for FTP and Telnet Sessions * Cisco IOS devices not configured with Authentication Proxy for HTTP(S) or the consent feature No other Cisco products are currently known to be affected by this vulnerability. Details ======= The Cisco IOS Firewall authentication proxy feature allows network administrators to apply specific security policies on a per-user basis. With the authentication proxy feature, users can log in to the network or access the Internet via HTTP, and their specific access profiles are automatically retrieved and applied from a CiscoSecure ACS, or other RADIUS or TACACS+ authentication server. The user profiles are active only when there is active traffic from the authenticated users. Web Authentication feature leverages the underlying authentication proxy feature. The consent feature for Cisco IOS routers enables organizations to provide temporary Internet and corporate access to end users through their wired and wireless networks by presenting a consent webpage. The consent feature can be used with or without requesting a username and password, but still leverages the underlying authentication proxy feature. This vulnerability allows a session to be permitted without first being authenticated by the authentication proxy, or to be permitted without first acknowledging the consent webpage. At least one successfully authenticated session or accepted consent session must exist for the vulnerability to be exposed. When this occurs, the RADIUS or TACACS+ server will show subsequent users as authenticated, all with the same username as the initial connection if performing authentication, regardless of the authentication information provided by the user and whether it was defined on the AAA server, and regardless of whether the password was correct. This vulnerability is caused by a race condition in the code, and several conditions outside the control of a malicious user and must be met before this vulnerability could be exploited.

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. Each row of the Cisco IOS Software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerability at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +-------------------------------------------------------------------+ | Major | Availability of Repaired Releases | | Release | | |------------+------------------------------------------------------| | Affected | | Recommended | | 12.0-Based | First Fixed Release | Release | | Releases | | | |------------+--------------------------------------+---------------| | 12.0 | Not Vulnerable | | |------------+--------------------------------------+---------------| | 12.0DA | Not Vulnerable | | |------------+--------------------------------------+---------------| | | Releases up to and including 12.0(4) | | | | DB are not vulnerable. | 12.4(23b) | | 12.0DB | | | | | Releases 12.0(7)DB and later are not | 12.4(25b) | | | vulnerable;

Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities. 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).
