CVE-2023-22273Network attack vector

Admin-authenticated code execution via unchecked publish path

Published Nov 17, 2023 · Updated Dec 16, 2025

Path traversal in Adobe RoboHelp Server 11.4 and earlier allows remote authenticated users with admin rights to execute arbitrary code. The OnPublishFile method uses a user-supplied path in file operations without validating that it remains in an allowed directory. Administrative authentication is required, and exploitation runs code in the RoboHelp Server service account context without user interaction.
