However, the user must provide the correct credentials in order to login to the VPN. A vulnerability exists in the Cisco ASA and Cisco PIX security appliances where VPN users can bypass authentication when the override account feature is enabled.\r\n\r\nNote: The override account feature was introduced in Cisco ASA software version 7.1(1).\r\n\r\nThe override account feature is enabled with the override-account-disable command in tunnel-group general-attributes configuration mode, as shown in the following example. The following example allows overriding the \"account-disabled\" indicator from the AAA server for the WebVPN tunnel group \"testgroup\":\r\n\r\n hostname(config)#tunnel-group testgroup type webvpn\r\n hostname(config)#tunnel-group testgroup general-attributes\r\n hostname(config-tunnel-general)#override-account-disable\r\n\r\nNote: The override account feature is disabled by default.", "sourceIdentifier": "ykramarz@cisco.com"}
