CVE-2023-25718Public exploitNetwork attack vector

User-assisted code execution via appended client configuration

Published Feb 13, 2023 · Updated Jun 19, 2025

Code-signing bypass in ConnectWise Control through 22.9.10032 allows remote attackers to run attacker-controlled code via a modified client. Configuration appended to an already signed client remains outside the validated signature and can redirect the client to download a different ClickOnce application from an attacker-controlled location. A victim must accept the download and execution prompt, and the demonstrated Host-header delivery path applies only to on-premises deployments.
