Descriptions

A vulnerability in TACACS authentication with Cisco Wireless LAN Controller (WLC) Software could allow an authenticated, local attacker to perform certain operations within the GUI that are not normally available to that user on the CLI. The vulnerability is due to incorrect parsing of a specific TACACS attribute received in the TACACS response from the remote TACACS server. An attacker could exploit this vulnerability by authenticating via TACACS to the GUI on the affected device. A successful exploit could allow an attacker to create local user accounts with administrative privileges on an affected WLC and execute other commands that are not allowed from the CLI and should be prohibited.

Una vulnerabilidad en la autenticación TACACS con Cisco Wireless LAN Controller (WLC) Software podría permitir que un atacante local autenticado realice ciertas operaciones en la interfaz de usuario que no deberían estar disponibles a ese usuario de la interfaz de línea de comandos. La vulnerabilidad se debe al análisis incorrecto de un atributo TACACS específico recibido en la respuesta TACACS desde el servidor TACACS remoto. Un atacante podría explotar esta vulnerabilidad autenticándose mediante TACACS en la interfaz de usuario de un dispositivo afectado. Su explotación con éxito podría permitir que un atacante cree cuentas de usuario local con privilegios administrativos en un WLC afectado y ejecute otros comandos que no se permiten desde la interfaz de línea de comandos y deberían estar prohibidos.
