Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software VPN Authorization Bypass Vulnerability

cisco-sa-asa-ftd-vp-authz-N2GckjN6 · Medium · Published · Updated

A vulnerability in the authentication and authorization flows for VPN connections in Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to establish a connection as a different user. This vulnerability is due to a flaw in the authorization verifications during the VPN authentication flow. An attacker could exploit this vulnerability by sending a crafted packet during a VPN authentication. The attacker must have valid credentials to establish a VPN connection. A successful exploit could allow the attacker to establish a VPN connection with access privileges from a different user. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
