Siemens S7-1500 CPU devices Missing Immutable Root of Trust in Hardware (CVE-2022-38773)

Affected devices do not contain an Immutable Root of Trust in Hardware. With this the integrity of the code executed on the device can not be validated during load-time. An attacker with physical access to the device could use this to replace the boot image of the device and execute arbitrary cod...
