ICSA-25-226-12: Siemens SIPROTEC 4 and SIPROTEC 4 Compact ↗ source

August 14, 2025 CISA ICS Advisory

Summary

SIPROTEC 4 and SIPROTEC 4 Compact devices contain a vulnerability that could allow an unauthenticated remote attacker to cause a denial of service condition. 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 countermeasures for products where fixes are not, or not yet available. CVE-2024-52504: Affected devices do not properly handle interrupted operations of file transfer. This could allow an unauthenticated remote attacker to cause a denial of service condition. To restore normal operations, the devices need to be restarted.

General Recommendations: Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. It is therefore recommended that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment.
