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).
