The vulnerability is an out-of-bounds write that could allow a remote attacker to cause memory corruption and potentially execute arbitrary code. This advisory covers the status of impact of various Siemens software products. Siemens has released new versions for the affected products and recommends to update to the latest versions. The following versions of Siemens Desigo, Gridscale are affected: Desigo CC family V8 vers:all\u002F* (CVE-2026-111497) Desigo CC family V9 vers:all\u002F* (CVE-2026-111497) Gridscale X DSA vers:intdot\u002F>=5.3| = V5.3 \u003C V5.4 Product Status: known_affected, known_not_affected Remediations Vendor fix Update to V5.4 or later version Gridscale X PSS®E \u003C V36.8.0 Product Status: known_affected, known_not_affected Remediations Vendor fix Update to V36.8.0 or later version Additional Metrics Relevant CWE: CWE-787 Out-of-bounds Write CVSS Version Base Score Base Severity Vector String 3.1 9.8 CRITICAL CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H View CVE Details Acknowledgments Siemens ProductCERT reported this vulnerability to CISA. 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. Recommended security guidelines can be found at: https:\u002F\u002Fwww.siemens.com\u002Fgridsecurity Additional Resources For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https:\u002F\u002Fwww.siemens.com\u002Fcert\u002Fadvisories Terms of Use The use of Siemens Security Advisories is subject to the terms and conditions listed on: https:\u002F\u002Fwww.siemens.com\u002Fproductcert\u002Fterms-of-use. Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and\u002For systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov\u002Fics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov\u002Fics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
