CVE-2022-39978Public exploitNetwork attack vector

Administrator-level code execution via unrestricted PHP upload

Published Oct 27, 2022 · Updated May 7, 2025

Unrestricted file upload in Online Pet Shop Web App 1.0 allows remote authenticated users to execute arbitrary PHP code. The save_product action in classes/Master.php accepts an img[] multipart file with a .php name, stores it under the web-accessible uploads directory, and permits its execution. Access to the Admin Panel's product-management function is required, and successful exploitation runs the uploaded script in the web server's context.
