Netgate pfSense CE desde la 2.7.0 hasta la 2.9.0 contiene una vulnerabilidad de inyección de comandos del sistema operativo que permite a usuarios autenticados con el privilegio de edición de QinQ ejecutar comandos almacenando un nombre de interfaz padre no validado. Los atacantes pueden guardar un valor 'if' manipulado y, a continuación, editar la entrada QinQ para que se interpole en los comandos de shell de ifconfig, ejecutando comandos como root.
