Software vendor:
Siemens

The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to the affected devices do not contain an Immutable Root of Trust in Hardware. An attacker with physical access can replace the boot image of the device and execute arbitrary code.

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
