Siemens Industrial Edge Management

Summary

Siemens Industrial Edge Management contains a critical authentication bypass vulnerability (CVE-2026-33892, CVSS 7.1) that allows unauthenticated remote attackers to circumvent authentication and access connected Industrial Edge Devices through the remote connection feature. The flaw affects Industrial Edge Management Pro V1 (versions ≥1.7.6 to <1.15.17), Pro V2 (≥2.0.0 to <2.1.1), and Virtual (≥2.2.0 to <2.8.0). Siemens has released patched versions and recommends immediate updates; exploitation requires knowledge of the remote connection header and port, with the remote feature enabled on the target device.

ICS Advisory Siemens Industrial Edge Management Release DateApril 21, 2026 Alert CodeICSA-26-111-11 Related topics: Industrial Control System Vulnerabilities, Industrial Control Systems View CSAF Summary Industrial Edge Management contains an authorization bypass vulnerability that could be exploited by an unauthenticated remote attacker to circumvent authentication and to access connected Industrial Edge Devices through the remote connection feature. Siemens has released new versions for the affected products and recommends to update to the latest versions. The following versions of Siemens Industrial Edge Management are affected: Industrial Edge Management Pro V1 vers:intdot/>=1.7.6|<1.15.17 (CVE-2026-33892) Industrial Edge Management Pro V2 vers:intdot/>=2.0.0|<2.1.1 (CVE-2026-33892) Industrial Edge Management Virtual vers:intdot/>=2.2.0|<2.8.0 (CVE-2026-33892) CVSS Vendor Equipment Vulnerabilities v3 7.1 Siemens Siemens Industrial Edge Management Authentication Bypass by Primary Weakness Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities Expand All + CVE-2026-33892 Affected management systems do not properly enforce user authentication on remote connections to devices. This could facilitate an unauthenticated remote attacker to circumvent authentication and impersonate a legitimate user. Successful exploitation requires that the attacker has identified the header and port used for remote connections to devices and that the remote connection feature is enabled for the device. Exploitation allows the attacker to tunnel to the device. Security features on this device itself (e.g. app specific authentication) are not affected.

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 (Download: 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. Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate 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 recent version available. Also recognize VPN is only as secure as its 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. 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 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.
