Summary
Siemens Desigo CC product family
Notes
Summary
Versions V5.0 through V7 of the Desigo CC product family (Desigo CC, Desigo CC Compact, Desigo CC Connect, Cerberus DMS) are affected by multiple vulnerabilities in the underlying third-party component WIBU Systems CodeMeter Runtime.
Successful exploitation of these vulnerabilities could allow remote attackers to execute arbitrary code on the Desigo CC server, or create a denial of service condition.
While all verison lines V5.0, V5.1 and V6 are affected by all listed vulnerabilities, V7 is only affected by CVE-2023-3935.
Siemens has released a patch to update the CodeMeter Runtime component and recommends to apply the patch on affected systems.
General Recommendations
As a general security measure Siemens strongly recommends to protect network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices in order to run the devices in a protected IT environment.
Additional Resources

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.
Recommended Practices
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Recommended Practices
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
Recommended Practices
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.
Recommended Practices
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
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.
Recommended Practices
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.
Recommended Practices
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

If CodeMeter is not configured as a server, the adversary would need to log in to the machine where the CodeMeter Runtime is running or trick the user into sending a malicious request to CodeMeter.
