Descriptions

The Authentication Proxy feature in Cisco IOS does not properly handle invalid AAA return codes from RADIUS and TACACS+ servers, which allows remote attackers to bypass authentication in opportunistic circumstances via a connection attempt that triggers an invalid code, as demonstrated by a connection attempt with a blank password, aka Bug IDs CSCuo09400 and CSCun16016.

La característica Authentication Proxy en Cisco IOS no maneja correctamente los códigos de retorno AAA inválidos de los servidores RADIUS y TACACS+, lo que permite a atacantes remotos evadir la autenticación en circunstancias oportunistas a través de un intento de conexión que provoca un código inválido, tal y como fue demostrado por un intento de conexión con una contraseña en blanco, también conocido como Bug IDs CSCuo09400 y CSCun16016.
