A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device contains an unrestricted USB port. An attacker with local access to the device could potentially misuse the port for booting another operating system and gain complete read/write access to the filesystem.
A missing immutable root of trust in the hardware results in the ability to bypass secure boot or execute untrusted or adversarial boot code.
