CVE-2022-46604Public exploitNetwork attack vector

Authenticated code execution via mismatched extension validation

Published Feb 2, 2023 · Updated Mar 27, 2025

Unrestricted file upload in Tecrail Responsive FileManager 9.9.5 and earlier allows remote authenticated users to execute PHP code. The create_file handler validates the extension of the name parameter, exempts the separate path parameter from the global extension check, and then writes new_content to that path. A valid file-manager session and enabled text-file creation are required; the resulting PHP file executes with the web server's privileges.
