CVE-2013-6707: Memory leak in the connection-manager implementation in Cisco Adaptive Security Appliance (ASA) Software 9....

Security readout for executives and security teams

CVE-2013-6707 is a denial-of-service issue in Cisco ASA management connections. Repeated management session requests can trigger a memory leak and cause a multi-protocol management outage. The cited record does not show data theft or firewall traffic bypass, but loss of management access can delay response during an incident. Organizations are most exposed if affected ASA management services are reachable from untrusted networks or broad internal segments. Exposure is lower where management access is tightly restricted and devices are already beyond ASA 9.1(3). Treat as a moderate operational resilience issue. It is most urgent for internet-reachable or broadly reachable firewall management planes, because management outage can impair incident response and network operations even without evidence of data compromise. Mitigation focus: Check Cisco’s security notice for official fixed-release or workaround guidance.; Inventory ASA devices and prioritize any running 9.1(3) or earlier.; Restrict management access to trusted administrative networks where feasible..
