A vulnerability in LevelOne WBR-6012 involves hard-coded credentials in its web services, allowing unauthorized access within the first 30 seconds after device boot. Attackers can bypass this time restriction by exploiting other vulnerabilities that force device reboot. The hard-coded password "AriesSerenaCairryNativitaMegan" is embedded in the firmware and grants user-level access. Although the password cannot be changed through normal means, authenticated users can change it by exploiting an additional vulnerability via HTTP POST parameters.
