The SIP inspection engine on Cisco Adaptive Security Appliances (ASA) 5500 series devices, and the ASA Services Module (ASASM) in Cisco Catalyst 6500 series devices, with software 8.2 before 8.2(5.17), 8.3 before 8.3(2.28), 8.4 before 8.4(2.13), 8.5 before 8.5(1.4), and 8.6 before 8.6(1.5) allows remote attackers to cause a denial of service (device reload) via a crafted SIP media-update packet, aka Bug ID CSCtr63728.

Security readout for executives and security teams

This flaw can make affected Cisco ASA firewalls or ASA Services Modules reload when they process a malicious SIP media-update packet. A reload can interrupt firewall and voice-related traffic, creating an availability risk for organizations that still run the listed old ASA software trains. Exposure is most likely in legacy Cisco ASA 5500 or ASASM deployments running the affected software and processing SIP through inspection. The bundle does not identify other Cisco platforms or supported modern releases as affected. Treat this as a high-priority legacy infrastructure availability issue. It is not described as data theft or code execution, but a firewall reload can interrupt connectivity and voice services. Focus on finding and upgrading exposed legacy ASA systems. Mitigation focus: Upgrade affected ASA software to the fixed version for the running train or later.; Review Cisco advisory cisco-sa-20121010-asa for vendor-approved workarounds or deployment-specific guidance.; Identify whether SIP inspection is required on affected devices..
