Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.3, adds an "HTTPS on Public Inbound (XML-Auto)(forward/in)" rule but sets the protocol to "ANY" when the XML filter configuration is enabled, which ultimately allows arbitrary traffic to pass through the concentrator.

Security readout for executives and security teams

This issue can weaken a Cisco VPN 3000 Concentrator from a controlled HTTPS/XML entry point into a path that permits unintended traffic. For executives, the concern is perimeter exposure: a VPN gateway meant to restrict traffic could allow broader inbound access when the XML filter configuration is enabled. Exposure is most likely in legacy Cisco VPN 3000 deployments running 2.2.x or 3.x before 3.5.3 with XML filter configuration enabled. Internet-facing concentrators carry the highest business risk. Treat as a priority legacy-perimeter review. If the device is internet-facing and affected, remediation should be scheduled urgently because the flaw undermines traffic restrictions at the VPN boundary. Mitigation focus: Confirm whether any Cisco VPN 3000 Concentrators remain in production.; Upgrade affected 3.x systems to 3.5.3 or later where applicable.; Review Cisco advisory guidance for supported fixes or workarounds..
