Descriptions

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.

Existe una vulnerabilidad de inyección de comandos en status_interfaces.php por medio de dhcp_relinquish_lease() en pfSense en versiones anteriores a la 2.4.4 debido a que pasa entradas de usuario de los parámetros $_POST "ifdescr" y "ipv" a un shell sin escapar el contenido de las variables. Esto permite que un usuario de la WebGUI autenticado con privilegios en la página afectada ejecute comandos en el contexto del usuario root al enviar una solicitud para renunciar a una asignación DHCP para una interfaz que está configurada para obtener su dirección mediante DHCP.
