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.

Fixes

Solution

Tycon Systems has released firmware 2.4.5, which resolves this vulnerability by requiring an administrator username and password to be set before the web interface is served. Further inquiries can be directed to security@tyconsystems.com. Tycon Systems recommends setting an administrative username and strong password on the Network Configuration page and confirming in a private browser window that a login is required, for units still running firmware 2.4.4 or earlier. Repeat this after any factory reset. Tycon Systems recommends not exposing the web interface to the Internet, as it is HTTP only. The unit should be kept on a private network, behind a firewall or VPN.

Type Values Removed Values Added
Description The web management interface of Tycon Systems TPDIN-Monitor-WEB2  does not perform server-side validation of credentials during the login process. By submitting empty values for both credential fields, an unauthenticated remote attacker can bypass the authentication check and establish a valid administrative session. This grants full access to device controls including power relay management, device reboot, remote access service configuration, and network settings, which could allow an attacker to disrupt connected infrastructure or cause physical damage to equipment.
