Netgate pfSense CE desde la 2.7.1 hasta la 2.9.0 contiene una vulnerabilidad de inyección CRLF en services_unbound_advanced.php que permite a usuarios autenticados con el privilegio DNS Resolver: Advanced inyectar directivas de Unbound. Los atacantes pueden incrustar caracteres CR/LF en el parámetro sock_queue_timeout, no validado, que se escribe sin procesar en unbound.conf, para anular los registros locales y el reenvío de todos los clientes.
