Siemens Industrial Edge Management
VulnView CSAF Summary Siemens is currently assessing the impact of Node2Shell (CVE-2026-111497) on Industrial Edge. Please check your Industrial Edge Management (IEM) setup: - No Management Applications installed: No action is required. Although the affected Brotli library is included in the IEM software stack, the affected functionality is not used or exposed. The same applies to IEDK. - Management Applications installed: Follow the specific mitigations until a fix is available. - Device Applications installed: Follow the specific mitigations until a fix is available. For Siemens-managed services, Industrial Edge Hub and Industrial Edge Management Cloud, appropriate Firewall/WAF protection has already been implemented. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fixes and recommends specific mitigations for products where fixes are not or not yet available. The following versions of Siemens Industrial Edge Management are affected: Cloud Connector Configurator vers:intdot/<1.24.3 (CVE-2026-111497) Common Configurator (CC on IEM) vers:all/* (CVE-2026-111497) Common Configurator on Device (CC on Edge) vers:all/* (CVE-2026-111497) Data Flow Monitoring vers:intdot/<3.0.18 (CVE-2026-111497) Databus Configurator vers:intdot/<4.0.1 (CVE-2026-111497) DataXess Configurator vers:intdot/<1.5.7 (CVE-2026-111497) Edge OPC UA Server Configurator vers:intdot/<2.3.10 (CVE-2026-111497) Flow Creator Configurator vers:intdot/<1.15.1 (CVE-2026-111497) Industrial Edge Hub vers:all/* (CVE-2026-111497) Industrial Edge Management Cloud vers:all/* (CVE-2026-111497) CVSS Vendor Equipment v3 9.8 Siemens Cloud Connector Configurator 1 Vulnerability Out-of-bounds Write Background Critical Infrastructure Sectors: Critical Manufacturing 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. Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1.

General Recommendations As a general security measure, Siemens strongly recommends protecting network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends configuring 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.
