Summary

A vulnerability has been identified in Desigo CC ClickOnce Client V6 (All versions), Desigo CC ClickOnce Client V7 (All versions), Desigo CC family V8 (All versions), Desigo CC family V9 (All versions), Desigo CC Flex Client V6 (All versions), Desigo CC Flex Client V7 (All versions), Desigo CC Installed Client V6 (All versions), Desigo CC Installed Client V7 (All versions). 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.
