Administrative access via boot-window hard-coded password
Published Oct 30, 2024 · Updated Nov 3, 2025
Hard-coded credentials in LevelOne WBR-6012 R0.40e6 allow remote attackers to gain administrative access through its web application. The authentication function compares the submitted password to an embedded backdoor string and returns the administrative access value when it matches. The backdoor is accepted only during the first 30 seconds after boot, but a forced reboot through another flaw reopens that window.
