TITLE

Cisco IOS of Firewall Vulnerability that prevents authentication in the authentication proxy function

DESCRIPTION

Race condition in the Firewall Authentication Proxy feature in Cisco IOS 12.0 through 12.4 allows remote attackers to bypass authentication, or bypass the consent web page, via a crafted request, aka Bug ID CSCsy15227. Cisco IOS is prone to a remote authentication-bypass vulnerability. Successfully exploiting this issue allows remote attackers to gain access to vulnerable devices without requiring successful authentication. This issue is being tracked by Cisco bug ID CSCsy15227. The username for the initial connection is the same. 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. 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 \xa9) 1986-2008 by cisco Systems, Inc.

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. 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. 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: http://intellishield.cisco.com/security/alertmanager/cvss CSCsy15227 - Cisco IOS Software Authentication Proxy Vulnerability CVSS Base Score - 7.1 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - None Availability Impact - None CVSS Temporal Score - 5.9 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability may result in an unauthenticated and unauthorized user bypassing the authentication proxy services offered in Cisco IOS Authentication Proxy for HTTP(S) and/or bypassing the consent accept webpage. 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. 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;

This can be exploited to cause a buffer overflow via specially crafted HTTP requests. Successful exploitation may allow execution of arbitrary code. 2) An error in the IKE implementation can be exploited to allocate all available Phase 1 SAs and prevent new IPSec sessions from being established. Successful exploitation requires that the IKE certificate based authentication method is used. 3) Multiple errors exist in the IP tunnelling implementation when switching network packets. These can be exploited to trigger a device reload via specially crafted packets. Successful exploitation requires that the device is configured for PPTP, GRE, IPinIP, Generic Packet Tunneling in IPv6, or IPv6 over IP tunnels, and Cisco Express Forwarding. 4) An error in the implementation of the Object Groups for ACLs feature can be exploited to bypass access control policies. 5) An error in the H.323 implementation can be exploited to trigger a device reload via specially crafted TCP packets. Successful exploitation requires that H.323 is enabled (disabled by default). 6) An error in the SIP implementation related to the Cisco Unified Border Element feature can be exploited to trigger a device reload. For more information: SA36836 7) An error in the SSLVPN, SSH, and IKE Encrypted Nonces features can be exploited to reload a device via specially crafted packets sent to TCP ports 22 (for SSH) or 443 (for SSLVPN), or UDP ports 500 and 4500 (for IKE Encrypted Nonces). 9) An error exists in the Cisco IOS Zone-Based Policy Firewall SIP inspection feature. This can be exploited to reload a device via a specially crafted SIP transit packet. 10) An error exists in the NTPv4 implementation while creating NTP reply packets. This can be exploited to trigger a device reload via a specially crafted NTP packet. SOLUTION: Update to a fixed version (please see the vendor's advisories for details). PROVIDED AND/OR DISCOVERED BY: 1, 3-10) Reported by the vendor. 2) Reported to the vendor by a customer.
