Authenticated OpenVPN daemon stop via newline injection
Published May 14, 2025 · Updated May 20, 2025
Command injection in Netgate pfSense CE before 2.8.0 and Plus before 25.07 allows remote authenticated users to stop OpenVPN daemons. The status_openvpn.php page and openvpn.widget.php pass the remipp value into openvpn_kill_client, which writes it after a kill command to the management socket without rejecting embedded newlines. Access to an affected page is required; injected management commands return no output, cannot run shell or PHP code, and do not persist after an OpenVPN restart.
