Descriptions

Cisco IOS 12.2 and earlier generates a "% Login invalid" message instead of prompting for a password when an invalid username is provided, which allows remote attackers to identify valid usernames on the system and conduct brute force password guessing, as reported for the Aironet Bridge.

Cisco IOS 12.2 y anteriores genera un mensaje "% Login Invalid" en vez de solicitar una contraseña cuando se suministra un nombre de usuario inválido, lo que permite a atacantes remotos identificar nombres de usuario válidos e intentar averiguar la contraseña con métodos de fuerza bruta, como ha informado Aironet Bridge.
