** DISPUTED ** An issue was discovered on Canon LBP6650, LBP3370, LBP3460, and LBP7750C devices. It is possible to bypass the Administrator Mode authentication for /tlogin.cgi via vectors involving frame.cgi?page=DevStatus. NOTE: the vendor reportedly responded that this issue occurs when a customer keeps the default settings without using the countermeasures and best practices shown in the documentation.
