CVE-2023-20269 is an improper authentication-path separation vulnerability in the Remote Access VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software. Improper separation of authentication, authorization, and accounting (AAA) between Remote Access VPN and the HTTPS management and site-to-site VPN features permits an attacker to specify a default connection profile or tunnel group. This allows unauthenticated brute-force attempts against credentials without the intended attempt restrictions. An authenticated attacker using valid credentials can also establish a clientless SSL VPN session as an unauthorized user on Cisco ASA releases 9.16 and earlier. The issue does not bypass authentication or MFA.
