Cisco PIX 500 and ASA 5500 Series Security Appliances 6.x before 6.3(5.115), 7.0 before 7.0(5.2), and 7.1 before 7.1(2.5), and the FWSM 3.x before 3.1(3.24), when the "inspect sip" option is enabled, allows remote attackers to cause a denial of service (device reboot) via malformed SIP packets.

Security readout for executives and security teams

This flaw can make older Cisco firewall appliances reboot when they process malformed SIP traffic while SIP inspection is enabled. The business impact is availability: a perimeter firewall reboot can interrupt voice or network traffic and weaken resilience during an incident. Exposure is mainly legacy Cisco PIX, ASA, or FWSM deployments still running affected releases with SIP inspection enabled. Risk is higher where SIP traffic can reach the appliance from untrusted networks. Prioritize if legacy Cisco firewalls still protect production networks or voice paths. A successful attack could interrupt connectivity by rebooting the appliance, but evidence of active exploitation is not provided. Mitigation focus: Upgrade affected Cisco PIX, ASA, and FWSM software to fixed releases or later.; Review Cisco vendor advisories for exact platform-specific remediation guidance.; Disable SIP inspection where it is not required and vendor guidance supports the change..
