Descriptions

A vulnerability in the authorization subsystem of Cisco IOS XE Software could allow an authenticated but unprivileged (level 1), remote attacker to run privileged Cisco IOS commands by using the web UI. The vulnerability is due to improper validation of user privileges of web UI users. An attacker could exploit this vulnerability by submitting a malicious payload to a specific endpoint in the web UI. A successful exploit could allow the lower-privileged attacker to execute arbitrary commands with higher privileges on the affected device.

Una vulnerabilidad en el subsistema de autorización del software Cisco IOS XE podría permitir que un atacante remoto autenticado sin privilegios (nivel 1) ejecute comandos Cisco IOS privilegiados mediante el uso de la interfaz web. Esta vulnerabilidad se debe a una validación incorrecta de los privilegios de usuario de los usuarios de la interfaz web. Un atacante podría explotar esta vulnerabilidad enviando una carga útil maliciosa a un endpoint específico en la interfaz web. Su explotación con éxito podría permitir que el atacante con pocos privilegios ejecute comandos arbitrarios con privilegios mayores en el dispositivo afectado.
