ICSA-24-284-10: Siemens SIMATIC S7-1500 CPUs
CISA advisory · released 2024-10-08
Source record Collected from CISA's CSAF advisory feed
- Distribution label in the document: TLP:WHITE
- Revision 8, 2025-10-14 (final)
CISA's summary
Summary: Several SIMATIC S7-1500 CPU versions are affected by an authentication bypass vulnerability that could allow an unauthenticated remote attacker to gain knowledge about actual and configured maximum cycle times and communication load of the CPU. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends countermeasures for products where fixes are not, or not yet available.

Vulnerabilities in this advisory
- CVE-2024-46887 — CVE-2024-46887 · CWE-288
The web server of affected devices do not properly authenticate user request to the '/ClientArea/RuntimeInfoData.mwsl' endpoint. This could allow an unauthenticated remote attacker to gain knowledge about current actual and configured maximum cycle times as well as about configured maximum communication load.
