Netgate pfSense CE 2.7.0 hasta 2.9.0 contiene una vulnerabilidad de inyección de configuración que permite a usuarios autenticados con privilegios de IPsec Mobile ejecutar comandos como root a través del campo login_banner. Los atacantes pueden enviar un banner de una sola línea que contenga '}' para escapar del valor attr sin comillas de strongswan.conf y definir entradas charon.start-scripts que charon ejecuta como root al reiniciarse.
