Descriptions

A vulnerability in Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to execute code with root privileges on an affected system. The vulnerability is due to insufficient input sanitization during user authentication processing. An attacker could exploit this vulnerability by sending a crafted response to the Cisco SD-WAN vManage Software. A successful exploit could allow the attacker to access the software and execute commands they should not be authorized to execute.

Una vulnerabilidad en el Cisco SD-WAN vManage Software podría permitir a un atacante remoto autenticado ejecutar código con privilegios root sobre un sistema afectado. La vulnerabilidad es debido a un saneamiento de entrada insuficiente durante el proceso de autenticación de usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de una respuesta diseñada al Cisco SD-WAN vManage Software. Un explotación con éxito podría permitir al atacante acceder al software y ejecutar comandos que no deberían estar autorizados a ejecutar
