Published Nov 4, 2024 · Updated Nov 4, 2024
Unrestricted file upload in Codezips Examination Seating Arrangement System 1.0 allows remote authenticated users to upload files. The save_user.php handler uses image data from $_FILES to choose the storage location without type validation or sanitization. Low-privileged access to the handler is required; an uploaded PHP script executes server-side, enabling code execution and file overwrite.
