CVE-2025-3169Public exploitNetwork attack vector

Authenticated code execution via filename filter bypass

Published Apr 3, 2025 · Updated Apr 3, 2025

Unrestricted file upload in ProjeQtOr 12.0.0 through 12.0.2 allows remote authenticated users to execute server-side PHP code. The /tool/saveAttachment.php handler writes attachmentFiles entries after filename filtering that can be bypassed with a semicolon or, on Windows, a trailing dot. Exploitation requires a valid session and an attachment directory exposed to the web; commands run with the web server process's privileges.
