CVE-2023-27440Network attack vector

Arbitrary file upload via failed import retention

Published Mar 26, 2024 · Updated Apr 28, 2026

Arbitrary file upload in OnTheGoSystems Toolset Types 3.4.17 and earlier allows remote authenticated users to place dangerous files. The import/export page accepts files without restricting their type, and failed imports retain those uploads on the server instead of removing them. Administrator access is required; public evidence does not establish automatic code execution from a retained file.
