Descriptions

A vulnerability in the log subscription subsystem of Cisco AsyncOS for the Cisco Secure Web Appliance (formerly Web Security Appliance) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. This vulnerability is due to insufficient validation of user-supplied input for the web interface and CLI. An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.

Una vulnerabilidad en el subsistema de suscripción de registros de Cisco AsyncOS para Cisco Secure Web Appliance (anteriormente Web Security Appliance), podría permitir a un atacante local autenticado llevar a cabo la inyección de comandos y elevar los privilegios a root. Esta vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario hacia la interfaz web y CLI. Un atacante podría explotar esta vulnerabilidad al autenticarse en el dispositivo afectado e inyectar comandos de scripting en el ámbito del subsistema de suscripción de registros. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios en el sistema operativo subyacente y elevar los privilegios a root
