CVE-2025-11500
HighSummary
Tinycontrol devices such as tcPDU and LAN Controllers LK3.5, LK3.9, and LK4 have two separate authentication mechanisms. When one of them is turned off (which is a default setting), an unauthenticated attacker on the local network can obtain usernames and encoded passwords for the interface management portal.
Risk Assessment
The organization is at risk of unauthorized access to credential data, which could lead to further attacks on systems and server resources.
Recommendation
It is recommended to update the firmware to the latest versions to enable appropriate authentication mechanisms and secure user data.

Original NVD description (English source)
Tinycontrol devices such as tcPDU and LAN Controllers LK3.5, LK3.9 and LK4 have two separate authentication mechanisms - one solely for interface management and one for protecting all other server resources. When the latter is turned off (which is a default setting), an unauthenticated attacker on the local network can obtain usernames and encoded passwords for interface management portal by inspecting the HTTP response of the server when visiting the login page, which contains a JSON file with these details. Both normal and admin users credentials are exposed. This issue has been fixed in firmware versions: 1.36 (for tcPDU), 1.67 (for LK3.5 - hardware versions: 3.5, 3.6, 3.7 and 3.8), 1.75 (for LK3.9 - hardware version 3.9) and 1.38 (for LK4 - hardware version 4.0).
