CVE-2022-45527Public exploitNetwork attack vector

Code execution via unrestricted PHP upload

Published Feb 8, 2023 · Updated Mar 25, 2025

Arbitrary file upload in Future-Depth Institutional Management Website 1.0 allows remote attackers to execute code via a crafted PHP file. The admin_area/course_insert.php handler retains the client-supplied filename without checking its type, then uses move_uploaded_file to store the upload under courseimg. The published assessment requires no privileges, although the disclosed request contains a session cookie; a stored PHP payload executes in the web server context.
