Authenticated code execution via unrestricted PHP upload
Published Oct 27, 2022 · Updated May 7, 2025
Unrestricted file upload in Online Pet Shop 1.0 allows remote attackers to execute arbitrary PHP through administrative profile editing. The profile-save handler accepts an img multipart field with a .php filename, stores the file under the browser-accessible /pet_shop/uploads directory, and permits direct execution. Administrative access to the account-management interface is required; successful exploitation runs attacker-supplied code in the PHP runtime process.
