ICS Advisory Siemens Industrial Edge Management Release DateSeptember 22, 2026 Alert CodeICSA-26-265-06 Related topics: Industrial Control System Vulnerabilities , Industrial Control Systems View CSAF Summary Industrial Edge Management contains an authentication bypass vulnerability that could allow an unauthenticated remote attacker to perform full account takeover by resetting user credentials without completing email verification. 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 Cloud vers:all/* (CVE-2026-18963) Industrial Edge Management Pro V1 vers:intdot/>=1.14.9|<1.15.20 (CVE-2026-18963) Industrial Edge Management Pro V2 vers:intdot/>=2.2.0|<2.2.2 (CVE-2026-18963) Industrial Edge Management Virtual vers:intdot/>=2.6.0|<2.9.1 (CVE-2026-18963) CVSS Vendor Equipment Vulnerabilities v3 9.1 Siemens Siemens Industrial Edge Management Weak Password Recovery Mechanism for Forgotten Password Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities Expand All + CVE-2026-18963 A flaw was found in the reset-credentials flow of the keycloak-services component, which is the core engine for identity and access management in Red Hat Build of Keycloak. The issue allows an unauthenticated attacker to force the password reset process for any user without needing to click the required email verification link. This can result in the attacker gaining full control over target user accounts by directly setting new credentials. View CVE Details Affected Products Siemens Industrial Edge Management Vendor:Siemens Product Version:Industrial Edge Management Cloud, Industrial Edge Management Pro V1 >= V1.14.9 < V1.15.20, Industrial Edge Management Pro V2 >= V2.2.0 < V2.2.2, Industrial Edge Management Virtual >= V2.6.0 < V2.9.1 Product Status:known_affected Remediations MitigationBlock direct internet access to IEM Pro / IEM Virtual The most effective immediate measure is to block direct internet access to your IEM Pro or IEM V instance. This ensures that no external attacks can occur via this vulnerability. MitigationConfigure a Web Application Firewall (WAF) or Reverse Proxy If complete blocking of internet access is not immediately feasible, you can use a Web Application Firewall (WAF) or a Reverse Proxy to block the affected path. Please configure your WAF or Reverse Proxy to block the following path: /auth/realms/customer/login-actions/reset-credentials Please note that by blocking this path, the password reset functionality will be unavailable. MitigationDeactivate Password Reset in Keycloak Realm Settings Deactivate the password reset functionality directly within the Keycloak realm settings. To do this, navigate to: Identity & access management > realm settings > Login > Forgot password > Off Please note that by deactivating this setting, the password reset functionality will be unavailable.

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 (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.
