The IPsec implementation in Cisco AnyConnect Secure Mobility Client 3.0 before 3.0.08057 does not verify the certificate name in an X.509 certificate, which allows man-in-the-middle attackers to spoof servers via a crafted certificate, aka Bug ID CSCtz26985.

Security readout for executives and security teams

This flaw affects legacy Cisco AnyConnect Secure Mobility Client 3.0 before 3.0.08057 when using IPsec. The client failed to verify the certificate name presented by a VPN server, so a network-positioned attacker could impersonate the server and intercept or manipulate VPN traffic. Exposure is most likely on unmanaged or legacy endpoints still running Cisco AnyConnect 3.0 earlier than 3.0.08057 with IPsec VPN profiles. Organizations using newer AnyConnect/Secure Client versions are less likely exposed, but endpoint inventory is needed to confirm. Treat this as a targeted legacy VPN client risk. It is not documented here as actively exploited, but VPN trust failures can expose credentials and sensitive traffic on unsafe networks. Prioritize confirming whether obsolete clients remain in use. Mitigation focus: Upgrade affected AnyConnect 3.0 clients to 3.0.08057 or later.; Review Cisco release notes and current Cisco guidance for supported upgrade paths.; Inventory endpoints for legacy AnyConnect 3.0 installations..
