CVE-2012-4659: The AAA functionality in the IPv4 SSL VPN implementations on Cisco Adaptive Security Appliances (ASA) 5500...

Security readout for executives and security teams

This issue can make affected Cisco ASA VPN devices reload, interrupting remote access and potentially other edge security functions. It affects specific ASA 8.2 and 8.3 software releases when IPv4 SSL VPN AAA handling is exposed. The source bundle does not confirm active exploitation. Exposure is most likely where Cisco ASA 5500 or Catalyst 6500 ASASM runs ASA 8.2 or 8.3 affected builds and provides IPv4 SSL VPN service. Prioritize if affected ASA devices support remote workforce or partner VPN access. A successful attack could create a visible outage at the network edge, but the provided sources do not show confirmed active exploitation. Mitigation focus: Identify ASA 5500 and ASASM devices running ASA 8.2 or 8.3.; Upgrade affected devices to Cisco fixed releases or vendor-recommended later versions.; Review Cisco advisory cisco-sa-20121010-asa for platform-specific upgrade guidance..
