Administrator password disclosure via direct resource request
Published Mar 16, 2026 · Updated Mar 16, 2026
Forced browsing in tinycontrol tcPDU, LK3.5, LK3.9, and LK4 firmware allows remote authenticated users to read the administrator password. The embedded web server permits a low-privileged account to request an administrator-only resource outside the graphical interface; its resource name is undisclosed. Exploitation requires low-privileged credentials and local-network reachability, and successful access discloses the administrator password.
