Descriptions

A vulnerability in the CLI of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as the root user. The attacker must be authenticated on the affected system as a low-privileged user to exploit this vulnerability. This vulnerability exists because a file leveraged by a root user is executed when a low-privileged user runs specific commands on an affected system. An attacker could exploit this vulnerability by injecting arbitrary commands to a specific file as a lower-privileged user and then waiting until an admin user executes specific commands. The commands would then be executed on the device by the root user. A successful exploit could allow the attacker to escalate their privileges on the affected system from a low-privileged user to the root user.

Una vulnerabilidad en la CLI del software Cisco SD-WAN vManage podría permitir a un atacante local autenticado ejecutar comandos arbitrarios en el sistema operativo subyacente como usuario root. El atacante debe estar autenticado en el sistema afectado como usuario con pocos privilegios para explotar esta vulnerabilidad. Esta vulnerabilidad se presenta porque un archivo aprovechado por un usuario root será ejecutado cuando un usuario con pocos privilegios ejecuta comandos específicos en un sistema afectado. Un atacante podría explotar esta vulnerabilidad al inyectar comandos arbitrarios en un archivo específico como usuario con pocos privilegios y luego esperar hasta que un usuario administrador ejecute comandos específicos. Los comandos serían entonces ejecutados en el dispositivo por el usuario root. Una explotación con éxito podría permitir al atacante escalar sus privilegios en el sistema afectado desde un usuario con pocos privilegios hasta el usuario root
