Description
The CleverDisplay BlueOne hardware player is designed with its USB interfaces physically enclosed and inaccessible under normal operating conditions. Researchers demonstrated that, after cicumventing the device’s protective enclosure, it was possible to connect a USB keyboard and press ESC during boot to access the BIOS setup interface. BIOS settings could be viewed but not modified. This behavior slightly increases the attack surface by exposing internal system information (CWE-1244) once the enclosure is removed, but does not allow integrity or availability compromise under standard or tested configurations.

CWE-1244
Internal Asset Exposed to Unsafe Debug Access Level or State
The product uses physical debug or test
interfaces with support for multiple access levels, but it
assigns the wrong debug access level to an internal asset,
providing unintended access to the asset from untrusted debug
agents.
