Summary
In Enterprise Networking Operating System (ENOS) in Lenovo and IBM RackSwitch and BladeCenter products, an authentication bypass known as "HP Backdoor" was discovered during a Lenovo security audit in the serial console, Telnet, SSH, and Web interfaces. This bypass mechanism can be accessed when performing local authentication under specific circumstances. If exploited, admin-level access to the switch is granted.
