Summary

SSA-534763: Special Register Buffer Data Sampling (SRBDS) aka Crosstalk in Industrial Products

Notes

Summary

Security researchers published information on a vulnerability known as Crosstalk (INTEL-SA-00320). This vulnerability affects modern Intel processors to a varying degree. Several Siemens Industrial Products contain processors that are affected by the vulnerability. Siemens has released updates for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where updates are not, or not yet available.

General Recommendations

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
