CVE-2025-11500 impacts Tinycontrol tcPDU and LAN Controllers (LK3.5, LK3.9, LK4), allowing an unauthenticated attacker on the local network to obtain interface management usernames and encoded passwords. This occurs due to a default insecure configuration where a secondary authentication mechanism is disabled, exposing credentials via HTTP response inspection on the login page. With a CVSS score of 8.7 HIGH, this vulnerability presents a severe risk, requiring only adjacent network access with low attack complexity and high impact on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, nor are public exploit codes or significant community discussion available for this vulnerability. Firmware updates are available to address this issue.
