Authenticated code execution via unrestricted event image upload

Published Sep 26, 2022 · Updated May 21, 2025

Arbitrary file upload in PHPGurukul Zoo Management System 1.0 allows remote authenticated users to execute code through an event image. The Events module's save_event endpoint accepts a multipart image named shell.php and stores it under the web-accessible img/event directory. Administrator access to the management system is required; requesting the stored PHP payload executes code with the web server's privileges.
