Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 8.2 through 8.4 process IKE requests despite a vpnclient mode configuration, which allows remote attackers to obtain potentially sensitive information by reading IKE responder traffic, aka Bug ID CSCtt07749.

Security readout for executives and security teams

Older Cisco ASA 5500 firewalls running software 8.2 through 8.4 may respond to IKE requests even when configured in vpnclient mode. A remote attacker could observe IKE responder traffic and learn potentially sensitive information. The public bundle does not provide CVSS scoring or detailed impact. Exposure is most likely on Cisco ASA 5500 devices running ASA software 8.2, 8.3, or 8.4 with vpnclient mode and reachable IKE services. The bundle does not identify other affected products. Treat this as a targeted perimeter-device information disclosure risk. It is not KEV-listed in the bundle, but affected VPN firewalls can expose sensitive handshake details and should be reviewed during network edge patch cycles. Mitigation focus: Inventory Cisco ASA 5500 devices and ASA software versions.; Review Cisco guidance for CSCtt07749 and applicable interim releases.; Prioritize devices exposing IKE to untrusted networks..
