"value": "An authenticated command injection vulnerability exists in status_interfaces.php via dhcp_relinquish_lease() in pfSense before 2.4.4 due to its passing user input from the $_POST parameters \"ifdescr\" and \"ipv\" to a shell without escaping the contents of the variables. This allows an authenticated WebGUI user with privileges for the affected page to execute commands in the context of the root user when submitting a request to relinquish a DHCP lease for an interface which is configured to obtain its address via DHCP."

Esto permite que un usuario de la WebGUI autenticado con privilegios en la p\u00e1gina afectada ejecute comandos en el contexto del usuario root al enviar una solicitud para renunciar a una asignaci\u00f3n DHCP para una interfaz que est\u00e1 configurada para obtener su direcci\u00f3n mediante DHCP."
