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.

The web management interface in Tycon Systems TPDIN-Monitor-WEB2

stores and displays system credentials in cleartext on a certain configuration page accessible to authenticated users. Any party with access to the administrative dashboard can immediately read these credentials, which may be used to compromise other systems on the local network.

Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior are vulnerable to a cross-site request forgery vulnerability. This could allow an attacker to perform state changing operations on the device.

Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior are vulnerable to a use of hard-coded credential vulnerability. This could allow an attacker to intercept sensitive information or credentials.
