Vulnerability from variot

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. Cisco VPN 3000 series concentrators are prone to an issue with XML filters which may inadvertently allow unauthorized network access to occur. This issue occurs when XML filters have been enabled on the public interface of the device. The vulnerable concentrator checks the destination port only when the value for the protocol is set to "TCP" or "UDP". Since the protocol is mistakenly set to "ANY", this will allow network connections using any protocol to an arbitrary port to occur through the concentrator. Cisco VPN 3000 Concentrator 2.2.x before 3.5.3, and 3.x versions have vulnerabilities

    "data": "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. Cisco VPN 3000 series concentrators are prone to an issue with XML filters which may inadvertently allow unauthorized network access to occur.  This issue occurs when XML filters have been enabled on the public interface of the device.  The vulnerable concentrator checks the destination port only when the value for the protocol is set to \"TCP\" or \"UDP\".  Since the protocol is mistakenly set to \"ANY\", this will allow network connections using any protocol to an arbitrary port to occur through the concentrator. Cisco VPN 3000 Concentrator 2.2.x before 3.5.3, and 3.x versions have vulnerabilities",
