Descriptions

A vulnerability in the user group configuration of the Cisco SD-WAN Solution could allow an authenticated, local attacker to gain elevated privileges on an affected device. The vulnerability is due to a failure to properly validate certain parameters included within the group configuration. An attacker could exploit this vulnerability by writing a crafted file to the directory where the user group configuration is located in the underlying operating system. A successful exploit could allow the attacker to gain root-level privileges and take full control of the device.

Una vulnerabilidad en la configuración del grupo de usuarios de la solución Cisco SD-WAN podría permitir a un atacante local autenticado obtener privilegios elevados en un dispositivo afectado. La vulnerabilidad se debe a un error a la hora de validar correctamente ciertos parámetros incluidos en la configuración "group". Un atacante podría explotar esta vulnerabilidad escribiendo un archivo manipulado en el directorio donde la configuración "user group" está ubicada en el sistema operativo subyacente. Un exploit exitoso podría permitir que el atacante obtenga privilegios de nivel root y obtenga el control total del dispositivo.
