CVE-2013-1193: The Secure Shell (SSH) implementation on Cisco Adaptive Security Appliances (ASA) devices, and in Cisco Fir...

Security readout for executives and security teams

This issue can let a remote attacker disrupt SSH management access on Cisco ASA and FWSM devices by repeatedly opening SSH connections. It affects device administration availability, not data confidentiality or firewall packet forwarding based on the supplied description. Exposure is limited to Cisco ASA and FWSM deployments with SSH management enabled. Risk is higher when SSH management is reachable from broad networks instead of controlled administrator paths. The bundle does not provide affected version ranges or CPEs. Treat this as a management-plane availability risk. Prioritize internet- or broadly reachable firewall management interfaces, but urgency is lower than code execution or data theft issues absent exploitation evidence. Mitigation focus: Review the Cisco security notice for affected releases, fixes, and workarounds.; Identify ASA and FWSM devices with SSH management enabled.; Prioritize devices where SSH management is reachable outside trusted administration networks..
