Descriptions

A vulnerability in the web UI 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 a failure to validate and sanitize input in Web Services Management Agent (WSMA) functions. An attacker could exploit this vulnerability by submitting a malicious payload to the affected device's 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 la interfaz web 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. La vulnerabilidad se debe al error a la hora de validar y sanear entradas en las funciones WSMA (Web Services Management Agent). Un atacante podría explotar esta vulnerabilidad enviando una carga útil maliciosa a la interfaz web de un dispositivo afectado. Su explotación con éxito podría permitir que el atacante con pocos privilegios ejecute comandos arbitrarios con privilegios mayores en el dispositivo afectado.
