CVE-2022-45476Public exploitNetwork attack vector

Remote code execution via executable file upload

Published Nov 25, 2022 · Updated Apr 29, 2025

Unrestricted file upload in Tiny File Manager 2.4.8 allows remote attackers to execute arbitrary PHP code on the hosting server. The upload path accepts a PHP payload, stores it beneath the web root, and serves it through PHP instead of forcing a download. Exploitation requires exposed upload and file-access paths; the published procedure uses CSRF to make an administrator submit the payload.
