Detailsinfo

A vulnerability was found in CleverDisplay BlueOne up to 12.11.1/12.12.0. It has been declared as problematic. Affected by this vulnerability is an unknown functionality. The manipulation with an unknown input leads to a internal asset exposed to unsafe debug access level or state vulnerability. The CWE definition for the vulnerability is CWE-1244. 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. As an impact it is known to affect confidentiality. The summary by CVE is:

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.

The weakness was released by Alwin Warringa, Tom Dantuma, Ruben Meeuwissen, And Ramon Dunker. and Dennis Kussendrager. It is possible to read the advisory at csirt.divd.nl. This vulnerability is known as CVE-2025-36755 since 04/15/2025. The exploitation appears to be easy. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.
