HTC Customer-Link Bridge (affected versions not specified)
**Description**
This issue allows adjacent attackers to inject arbitrary Controller Area Network messages on vulnerable installations. Authentication is not required to exploit this issue. The specific flaw exists within the Customer-Link App and Customer-Link Bridge, resulting from the lack of a proper protection mechanism against unauthorized firmware updates. An attacker can leverage this issue to inject CAN messages.
**Recommendations**
