Siemens Desigo CC family

View CSAF Summary A Client Code Execution (CCE) vulnerability has been identified in Desigo CC, potentially allowing malicious actors to execute arbitrary code on client devices through specially crafted graphics documents. This vulnerability leverages user-defined graphics containing embedded scripts that are executed on client application instances. Successful exploitation could lead to compromise of the client operating system and potential lateral movement within the organization. The following versions of Siemens Desigo CC family are affected: Desigo CC family V6 vers:all/* (CVE-2026-34223) Desigo CC family V7 vers:all/* (CVE-2026-34223) CVSS Vendor Equipment Vulnerabilities v3 8.2 Siemens Siemens Desigo CC family Improper Control of Generation of Code ('Code Injection') Background Critical Infrastructure Sectors: Critical Manufacturing, Commercial Facilities Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities Expand All + CVE-2026-34223 The affected application is vulnerable to Client Code Execution (CCE) due to insufficient input validation when handling scripts embedded within user-defined graphics documents. Specifically, when the script within a graphics document is designed or modified by an attacker to include malicious commands. When a user opens a compromised graphics document, the embedded script is executed on the client application instance, allowing an attacker to write arbitrary files to the client's operating system. Successful exploitation requires an attacker to craft a malicious graphics document and entice a user with sufficient privileges to display it. This could lead to compromise of the client operating system and potential lateral movement within the organization.

General Security Recommendations Schneider Electric strongly recommends the following industry cybersecurity best practices. Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network. Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. Place all controllers in locked cabinets and never leave them in the “Program” mode. Never connect programming software to any network other than the network intended for that device. Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks. Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. * When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

General Security Recommendations Schneider Electric strongly recommends the following industry cybersecurity best practices. Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network. Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. Place all controllers in locked cabinets and never leave them in the “Program” mode. Never connect programming software to any network other than the network intended for that device. Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks. Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices. For more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document .

Using Cyber Decoys to Strengthen Detection and Response

CISA developed this guidance to help defensive teams at varying levels of cybersecurity maturity plan and implement cyber decoy strategies that strengthen their detection and response capabilities. Many organizations struggle to detect adversaries who use legitimate credentials, native tools, and living off the land (LOTL) techniques to conduct discovery, move laterally, and access data. Cyber decoys are assets that appear to be legitimate systems, accounts, or data, but are designed to distract adversaries, detect their presence, or facilitate collection of cyber threat intelligence (CTI). As organizations adopt Zero Trust models, they should assume that a malicious threat actor may gain some level of access to their environment and plan accordingly. Cyber decoys complement Zero Trust by: Supporting continuous monitoring and verification, Creating high-fidelity alerts for suspicious activity, Reducing alert fatigue, and Helping defenders detect post-compromise activity, including adversary LOTL techniques. This guidance introduces decoy concepts—including tripwires, breadcrumbs, and honeytokens—and uses the MITRE Engage™ and MITRE ATT&CK® frameworks to provide practical, low-complexity steps for planning, implementing, and refining decoy operations. For additional information, visit CISA’s Best Practices for MITRE ATT&CK Mapping .

General Security Recommendations Schneider Electric strongly recommends the following industry cybersecurity best practices: Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network. Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. Place all controllers in locked cabinets and never leave them in the “Program” mode. Never connect programming software to any network other than the network intended for that device. Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks. Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices. For more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document.
