CISA's summary
Summary: Affected models of the S7-1500 CPU product family 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 code. As exploiting this vulnerability requires physical tampering with the product, Siemens recommends to assess the risk of physical access to the device in the target deployment and to implement measures to make sure that only trusted personnel have access to the physical hardware. The vulnerability is related to the hardware of the product. Siemens has released new hardware versions for several CPU types of the S7-1500 product family in which this vulnerability is fixed and is working on new hardware versions for remaining PLC types to address this vulnerability completely. See the chapter "Additional Information" below for more details. For more information please also refer to the related product support article: https://support.industry.siemens.com/cs/ww/en/view/109816536/.
