1. EXECUTIVE SUMMARY CVSS v3 8.2 ATTENTION: Low attack complexity Vendor: Siemens Equipment: Desigo CC Product Family and SENTRON Powermanager Vulnerability: Least Privilege Violation
2. RISK EVALUATION Successful exploitation of this vulnerability could allow privilege escalation.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Siemens reports that the following products are affected: Desigo CC family V5.0: All versions Desigo CC family V5.1: All versions Desigo CC family V6: All versions Desigo CC family V7: All versions Desigo CC family V8: All versions SENTRON Powermanager V5: All versions SENTRON Powermanager V6: All versions SENTRON Powermanager V7: All versions SENTRON Powermanager V8: All versions 3.2 VULNERABILITY OVERVIEW 3.2.1 LEAST PRIVILEGE VIOLATION CWE-272 Wibu CodeMeter before 8.30a sometimes allows privilege escalation immediately after installation (before a logoff or reboot). For exploitation, there must have been an unprivileged installation with UAC, and the CodeMeter Control Center component must be installed, and the CodeMeter Control Center component must not have been restarted. In this scenario, the local user can navigate from Import License to a privileged instance of Windows Explorer. CVE-2025-47809 has been assigned to this vulnerability. A CVSS v3.1 base score of 8.2 has been calculated; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: Germany 3.4 RESEARCHER Siemens reported this vulnerability to CISA.
4. MITIGATIONS Siemens has identified the following specific workarounds and mitigations users can apply to reduce risk: Please follow below steps to update the WIBU CodeMeter : Uninstall the previous installed version of CodeMeter via Control Panel Install the CodeMeter V8.30a (Refer: https://www.wibu.com/us/support.html) Restart client/server after installation of CodeMeter For more details regarding the vulnerability in CodeMeter Runtime refer to: WIBU Systems Security Advisory WIBU-100120: https://www.wibu.com/support/security-advisories/wibu-100120.html As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ operational guidelines for industrial security and following recommendations in the product manuals. Additional information on industrial security by Siemens can be found on the Siemens industrial security webpage For more information see the associated Siemens security advisory SSA-201595 in HTML and CSAF. CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as: 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). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are 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. 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. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
