Netgate pfSense CE hasta la versión 2.9.0 contiene una vulnerabilidad de inyección en php.ini que permite a usuarios autenticados con privilegios de Configuración general inyectar directivas mediante el envío de un valor de zona horaria no validado. Los atacantes pueden incluir una comilla y un salto de línea para añadir auto_prepend_file apuntando a /var/db/zoneinfo, ejecutando PHP como root después de que php.ini se regenere al arrancar o al reiniciar php-fpm.
