TITLE

Cisco Firewall Services Module vulnerable to DoS via inspection of malformed SIP messages

Trust: 0.8

sources: CERT/CC: VU#430969

DESCRIPTION

Cisco Firewall Services Module (FWSM) 3.x before 3.1(3.11), when the HTTPS server is enabled, allows remote attackers to cause a denial of service (device reboot) via certain HTTPS traffic. Cisco Firewall Services Module fails to properly inspect SIP messages. This vulnerability may allow a remote attacker to cause a denial of service condition. Multiple Cisco products are prone to multiple denial-of-service vulnerabilities. Attackers can exploit these issues to cause vulnerable devices to reload, potentially causing denial-of-service conditions. Multiple security vulnerabilities exist in Cisco PIX 500 Series Security Appliances and Cisco ASA 5500 Series Adaptive Security Appliances: Enhanced Inspection Malformed HTTP Traffic +--------------------- -------------------------- Cisco PIX and ASA Security Appliances may crash when checking for malformed HTTP requests if Enhanced HTTP Inspection is enabled . If HTTP application inspection is enabled, the configuration will contain a line similar to inspect http, where the name of the specific HTTP mapping. Note that normal HTTP inspection (configured via inspect http, without HTTP mapping) is not affected by this vulnerability. This vulnerability is documented in Cisco Bug ID as CSCsd75794. To trigger this vulnerability, the SIP fixup (for 6.x software) or inspect (for 7.x software) function must be enabled. SIP fixup (in 6.x and earlier) and SIP check (in 7. x and earlier) is enabled by default. This vulnerability is documented in Cisco Bug IDs as CSCsd97077 and CSCse27708. Check malformed TCP packet flow+------------------------------------------- ------ Cisco PIX and ASA equipment may crash when processing malformed packet flow based on TCP protocol. Protocols must be handled through the inspect function. The message may be sent to the device, or it may only pass through the device. Cisco PIX and ASA appliances can inspect the following TCP-based protocols: * Computer Telephony Interface Quick Buffer Encoding (CITQBE) * Distributed Computing Environment/Remote Procedure Call (DCE/RPC) * Domain Name Service (DNS) * Extended Simple Mail Transfer Protocol (ESMTP) * File Transfer Protocol (FTP) * H.323 Protocol * Hypertext Transfer Protocol (HTTP) * Internet Location Server (ILS) * Instant Messaging (IM) * Point-to-Point Tunneling Protocol (PPTP) * Remote Shell (RSH ) * Real Time Streaming Protocol (RTSP) * Session Initiation Protocol (SIP) *... ---------------------------------------------------------------------- Secunia is proud to announce the availability of the Secunia Software Inspector. The Secunia Software Inspector is a free service that detects insecure versions of software that you may have installed in your system. When insecure versions are detected, the Secunia Software Inspector also provides thorough guidelines for updating the software to the latest secure version from the vendor. 1) An unspecified error within the enhanced inspection of HTTP traffic can be exploited to cause the device to reload via specially crafted HTTP traffic. Successful exploitation requires that enhanced inspection is enabled. 2) An error within the inspection of SIP packets can be exploited to cause the device to reload via specially crafted SIP packets. Successful exploitation requires that SIP inspection is enabled. 3) An unspecified error when processing malformed HTTPS requests can be exploited to cause the device to reload by sending specially crafted HTTPS requests. Successful exploitation requires that "authentication for network access" (auth-proxy) is enabled. 4) An error when processing HTTP requests with a very long URL can be exploited to cause the device to reload, but requires that "authentication for network access" (auth-proxy) is enabled. 5) An unspecified error exists when processing HTTPS traffic that is directed to the FWSM. 6) An unspecified error when processing malformed SNMP requests from a trusted device can be exploited to cause the affected device to reload. Successful exploitation requires that the other, trusted device has explicit SNMP poll access. 7) A security issue when manipulating ACLs (Access Control Lists) that make use of object groups can corrupt ACLs, resulting in ACEs (Access Control Entries) being skipped or not evaluated in order, which can be exploited to bypass certain security restrictions. Note: Only an administrative user can change ACLs. Additionally, this does not affected devices which are reloaded after ACLs have been manipulated. A vulnerability that could cause the device to reload when "debugging" is enabled has also been reported. SOLUTION: Apply updated software. Please see vendor advisory for a patch matrix. PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
