CVE-2026-61884

CRITICAL

Tycon Systems TPDIN-Monitor-WEB2 Authentication Bypass Using an Alternate Path or Channel

Title source: cna
STIX 2.1

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.
