Unauthenticated PHP file upload

Published Jul 12, 2023 · Updated Nov 7, 2024

Unrestricted file upload in Online Piggery Management System 1.0 allows remote attackers to upload a PHP file via an unauthenticated POST request. The add-pig.php handler accepts the pigphoto multipart filename and moves the uploaded temporary file into uploadfolder without restricting dangerous extensions. An attacker needs no account or user interaction; if the web server executes uploaded PHP files, the upload can provide code execution and compromise application data.
