Netgate pfSense CE desde la 2.7.1 hasta la 2.9.0 contiene una vulnerabilidad de secuencias de comandos en sitios cruzados (XSS) reflejada en firewall_rules.php que permite a atacantes remotos inyectar secuencias de comandos mediante el parámetro if sin codificar. Cuando se activa la opción no predeterminada Require Firewall Interface, los atacantes pueden engañar a usuarios con privilegios sobre las reglas de cortafuegos para que abran un enlace GET manipulado y ejecuten secuencias de comandos en la WebGUI con sus privilegios.
