Authenticated code execution via unsigned extension upload
Published Jan 23, 2020 · Updated Aug 5, 2024
Remote code execution in ConnectWise Control 19.3.25270.7185 allows remote authenticated users to run code through an extension upload. InstallExtension accepts a Base64-encoded ZIP without a valid signature, and a direct request to the uploaded ASHX handler causes the server to execute it. Administrative access is required, and successful exploitation runs attacker-controlled code in the Control server's security context.
