Siemens Desigo, Gridscale
View CSAF Summary On October 21, 2026, the Node.js project released security updates addressing a critical vulnerability in the Brotli decoder bundled with Node.js, commonly referred to as "Node2Shell" (tracked as CVE-2026-111497). 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/* (CVE-2026-111497) Desigo CC family V9 vers:all/* (CVE-2026-111497) Gridscale X DSA vers:intdot/>=5.3|<5.4 (CVE-2026-111497) Gridscale X PSS®E vers:intdot/<36.8.0 (CVE-2026-111497) CVSS Vendor Equipment v3 9.8 Siemens Desigo CC family V8 1 Vulnerability Out-of-bounds Write Background Critical Infrastructure Sectors: Critical Manufacturing, Energy, Information Technology Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities CVE-2026-111497 A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream.

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).

Siemens Building Automation and Energy Products
View CSAF Summary On October 21, 2026, the PHP project and security researchers disclosed two critical, unauthenticated remote code execution vulnerabilities in the core PHP language runtime known as "php2shell" (tracked as CVE-2026-109618 and CVE-2026-109619). This advisory covers the status of impact of various Siemens software products. 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, and to follow the recommendations in the product manuals. Siemens is actively monitoring the situation and assessing the implications of these vulnerabilities on our portfolio. Because this evaluation is ongoing, our findings are subject to change as new technical details and vendor updates emerge. We will publish updated findings, guidance, and remediation recommendations as soon as they become available. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fixes and recommends mitigations for products where fixes are not or not yet available.

The following versions of Siemens RUGGEDCOM APE1808 are affected: RUGGEDCOM APE1808 vers:all/* (CVE-2026-109618, CVE-2026-109619) CVSS Vendor Equipment v3 9.8 Siemens RUGGEDCOM APE1808 1 Vulnerability Use After Free Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities Expand All + CVE-2026-109618 PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the request. Some contexts may not properly account for this scenario and leave request memory in an uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote code execution (RCE).

In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE).

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 (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. 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/or 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/ics. 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/ics 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.
