Netgate pfSense CE 2.7.0 hasta 2.9.0 contiene una vulnerabilidad de inyección de comandos del sistema operativo que permite a usuarios autenticados con privilegios de Traffic Shaper Limiters ejecutar comandos como root manipulando el campo de número del limitador. Los atacantes pueden enviar un valor 'number' oculto malicioso al editar un limitador y, a continuación, eliminarlo, de modo que delete_queue() pasa el valor sin entrecomillar a dnctl a través de /bin/sh como root.
