This is a hardware vulnerability in certain PCBs used in some devices. It allows an attacker to exploit the UART port as a side-channel attack to obtain root access on the device.
This is a hardware vulnerability in certain PCBs used in some devices. It allows an attacker to exploit the UART port as a side-channel attack to obtain root access on the device.
Specific version info not stated in the advisory. If you don't recognise this software, you're probably not affected.
Contact DynamiApps directly for a patched PCB design - there's no public patch link in the advisory.
Immediate mitigations:
- Inspect your device for any signs of tampering or unauthorized access
- Immediately disconnect power to prevent further exploitation
- Replace the affected PCB with a known-good one if possible
