**Name of the Vulnerable Software and Affected Versions** Phoenix Contact mGuard Devices versions prior to 8.8.3 **Description** The issue concerns the functionality of LAN ports on Phoenix Contact mGuard Devices. Even if these ports are disabled in the device configuration, they become functional after a reboot. This behavior is observed in devices with an integrated switch on the LAN side, where single switch ports can be disabled through device configuration, but they still become functional after a reboot, independent of their configuration setting. **Recommendations** For versions prior to 8.8.3, update to version 8.8.3 or later to resolve the issue.
