FKIE_CVE-2025-15587

Vulnerability from fkie_nvd - Published: 2026-03-16 14:17 - Updated: 2026-06-17 08:38
Severity
8.6 (High) - CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
Tinycontrol devices such as tcPDU and LAN Controllers LK3.5, LK3.9 and LK4 allow a low privileged user to read an administrator's password by directly accessing a specific resource inaccessible via a graphical interface. 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).
