Vulnerability from csaf_siemens - Published: 2023-02-14 00:00 - Updated: 2026-08-11 00:00Summary
SSA-686975: IPU 2022.3 Vulnerabilities in Siemens Industrial Products using Intel CPUs
Notes
Summary: Intel has published information on vulnerabilities in Intel products in November 2022. This advisory lists the related Siemens Industrial products affected by these vulnerabilities that can be patched by applying the corresponding BIOS update ("2022.3 IPU – BIOS Advisory" Intel-SA-00688).
Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes 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.
Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
Additional Resources: For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories
Terms of Use: The use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use.
Time-of-check time-of-use race condition in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.
