Official description
The Tycon Systems TPDIN-Monitor-WEB2 ships without HTTP credentials configured, intended for an installer to set them on first use. On firmware 2.4.4 and earlier, a unit left in this unconfigured state serves the web management interface without requiring any login. An attacker with network access to such a unit can reach full device controls, including power relay management, device reboot, remote access service configuration, and network settings, which could allow disruption of connected infrastructure or physical damage to equipment.
