Descriptions

A vulnerability in the web-based user interface (Web UI) of Cisco IOS XE Software could allow an authenticated, remote attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability occurs because the affected software improperly sanitizes user-supplied input. An attacker who has valid administrator access to an affected device could exploit this vulnerability by supplying a crafted input parameter on a form in the Web UI and then submitting that form. A successful exploit could allow the attacker to run arbitrary commands on the device with root privileges, which may lead to complete system compromise.

Una vulnerabilidad en la interfaz de usuario basada en web (Web UI) de Cisco IOS XE Software podría permitir a un atacante remoto autenticado ejecutar comandos en el shell Linux subyacente de un dispositivo afectado con privilegios de root. La vulnerabilidad se produce porque el software afectado valida incorrectamente la entrada suministrada por el usuario. Un atacante que tenga acceso válido de administrador a un dispositivo afectado podría explotar esta vulnerabilidad suministrando un parámetro de entrada diseñado en un formulario en la interfaz de usuario de la Web, y luego enviando ese formulario. Un exploit exitoso podría permitir al atacante ejecutar comandos arbitrarios en el dispositivo con privilegios de root, lo que puede llevar a un compromiso completo del sistema.
