-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Cisco Security Advisory: Multiple Vulnerabilities in Cisco Firewall Services Module Advisory ID: cisco-sa-20111005-fwsm Revision 1.0 For Public Release 2011 October 05 1600 UTC (GMT) +--- Summary === The Cisco Firewall Services Module (FWSM) for the Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers is affected by the following vulnerabilities: * Syslog Message Memory Corruption Denial of Service Vulnerability * Authentication Proxy Denial of Service Vulnerability * TACACS+ Authentication Bypass Vulnerability * Sun Remote Procedure Call (SunRPC) Inspection Denial of Service Vulnerabilities * Internet Locator Server (ILS) Inspection Denial of Service Vulnerability These vulnerabilities are not interdependent; a release that is affected by one vulnerability is not necessarily affected by the others. Cisco has released free software updates that address these vulnerabilities. Workarounds are available for some of the vulnerabilities disclosed in this advisory. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20111005-fwsm.shtml Note: Cisco ASA 5500 Series Adaptive Security Appliances and the Cisco Catalyst 6500 Series ASA Services Module are affected by some of the vulnerabilities described in this advisory. A separate Cisco Security Advisory has been published to disclose these and other vulnerabilities that affect the Cisco ASA 5500 Series Adaptive Security Appliances and the Cisco Catalyst 6500 Series ASA Services Module. The advisory is available at: http://www.cisco.com/warp/public/707/cisco-sa-20111005-asa.shtml Affected Products = Vulnerable Products +-- The Cisco FWSM for the Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers is affected by multiple vulnerabilities. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. Refer to the Software Version and Fixes section for specific information on vulnerable versions. Syslog Message Memory Corruption Denial of Service Vulnerability +--- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if the following conditions are satisfied: * The device has interfaces with IPv6 addresses * System logging is enabled (command logging enable) * The device is configured in any way to generate system log message 302015 (refer to the following examples) System log message 302015 has a default severity level of 6 (informational) so, assuming that the system administrator has not changed this default severity level, the vulnerability can be triggered if the device is logging to any destination at level 6 or level 7 (debug). As an example, the following configuration is vulnerable: logging enable ! logging console informational logging buffered informational [...] Using a custom message list (via the logging list command) that includes system log message 302015, either by severity or by explicitly including the message ID, is also a vulnerable configuration. For example, the following configuration is also vulnerable: logging enable ! logging list MYLIST level informational and/or logging list MYLIST message 302015 ! logging trap MYLIST Note: The default severity level of system log messages can be changed. If the default severity level of system log message 302015 is changed, and the device is configured to log to any destination at the new severity level, then the device is still vulnerable. Authentication Proxy Denial of Service Vulnerability +--- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use Authentication, Authorization, and Accounting (AAA) for network access, also known as cut-through or authentication proxy. The network access authentication feature is enabled if the aaa authentication match or aaa authentication include commands are present in the configuration of an affected device. TACACS+ Authentication Bypass Vulnerability +-- Devices running vulnerable versions of Cisco FWSM Software are affected by this vulnerability if they are configured to use the Terminal Access Controller Access-Control System Plus (TACACS+) protocol for AAA. A device is configured for TACACS+ if an AAA server group is defined in a manner similar to the following: aaa-server my-tacacs-server protocol tacacs+ aaa-server my-tacacs-server (inside) host 192.168.1.1 [...] Note: In the preceding example, my-tacacs-server is the name of the AAA server group.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Cisco Security Advisory: Multiple Vulnerabilities in Cisco Firewall Services Module Advisory ID: cisco-sa-20100804-fwsm Revision 1.0 For Public Release 2010 August 04 1600 UTC (GMT) +- Summary === Multiple vulnerabilities exist in the Cisco Firewall Services Module (FWSM) for the Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers that may cause the Cisco FWSM to reload after processing crafted SunRPC or certain TCP packets. Repeated exploitation could result in a sustained DoS condition. Cisco has released free software updates that address these vulnerabilities. Workarounds are available for the vulnerabilities disclosed in this advisory. Note: These vulnerabilities are independent of each other. A device may be affected by one vulnerability and not affected by another. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20100804-fwsm.shtml Note: The Cisco ASA 5500 Series Adaptive Security Appliances are affected by the SunRPC inspection vulnerabilities described in this advisory. A separate Cisco Security Advisory has been published to disclose this and other vulnerabilities that affect the Cisco ASA 5500 Series Adaptive Security Appliances. The advisory is available at: http://www.cisco.com/warp/public/707/cisco-sa-20100804-asa.shtml Affected Products = Vulnerable Products +-- The Cisco Firewall Services Module (FWSM) for the Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers is affected by multiple vulnerabilities. Affected versions of Cisco FWSM Software vary depending on the specific vulnerability. SunRPC Inspection Denial of Service Vulnerabilities ~~~ Cisco FWSM Software version 3.x and 4.x are affected by these vulnerabilities only if SunRPC inspection is enabled. SunRPC inspection is enabled by default. To check if SunRPC inspection is enabled, use the show service-policy | include sunrpc command and confirm that the command returns output, as shown in the following example: fwsm#show service-policy | include sunrpc Inspect: sunrpc , packet 0, drop 0, reset-drop 0 Alternatively, a device that has SunRPC inspection enabled has a configuration similar to the following: class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default ... inspect sunrpc ... ! service-policy global_policy global Note: The Cisco ASA 5500 Series Adaptive Security Appliances are affected by the SunRPC inspection vulnerabilities described in this advisory. A separate Cisco Security Advisory has been published to disclose this and other vulnerabilities that affect the Cisco ASA 5500 Series Adaptive Security Appliances. The advisory is available at: http://www.cisco.com/warp/public/707/cisco-sa-20100804-asa.shtml TCP Denial of Service Vulnerability ~~~ Cisco FWSM Software version 3.x and 4.x are affected by this vulnerability when configured in multi-mode (with virtual firewalls) and with any of the following features: * ASDM Administrative Access * Telnet * SSH To verify if the FWSM is running in multiple mode, use the show mode command, as shown in the following example: FWSM(config)#show mode Security context mode: multiple The flash mode is the SAME as the running mode. The following commands are used to enable the HTTPS server and allow only hosts on the inside interface with an address in the 192.168.1.0 /24 network to create ASDM, SSH or Telnet connections: asa(config)# http server enable asa(config)# http 192.168.1.0 255.255.255.0 inside asa(config)# telnet 192.168.1.0 255.255.255.0 inside asa(config)# ssh 192.168.1.0 255.255.255.0 inside Determining Software Versions ~ To determine the version of Cisco FWSM Software that is running, issue the show module command from Cisco IOS Software or Cisco Catalyst Operating System Software to identify what modules and sub modules are installed on the system. The following example shows a system with a Cisco FWSM (WS-SVC-FWM-1) installed in slot 2: switchshow module Mod Ports Card Type Model Serial No. --- - -- -- --- 1 16 SFM-capable 16 port 1000mb GBICWS-X6516-GBIC SAL06334NS9 26 Firewall ModuleWS-SVC-FWM-1 SAD10360485 38 Intrusion Detection System WS-SVC-IDSM-2 SAD0932089Z 44 SLB Application Processor Complex WS-X6066-SLB-APC SAD093004BD 52 Supervisor Engine 720 (Active) WS-SUP720-3B SAL0934888E Mod MAC addresses
