Vulnerability from github – Published: 2025-02-11 12:30 – Updated: 2025-11-04 00:32

Details

A serial interface can be accessed with physical access to the PCB of Wattsense Bridge devices. After connecting to the interface, access to the bootloader is possible, as well as a Linux login prompt. The bootloader access can be used to gain a root shell on the device. This issue is fixed in recent firmware versions BSP >= 6.4.1.

Severity ?

6.8 (Medium)
