CVE-2025-3042Public exploitNetwork attack vector

Authenticated code execution via unrestricted PHP upload

Published Apr 1, 2025 · Updated Apr 1, 2025

Unrestricted file upload in Project Worlds Online Time Table Generator 1.0 allows remote authenticated users to execute PHP code. The pic handler in student/updateprofile.php accepts the client-supplied filename without type or extension checks and passes the temporary file directly to move_uploaded_file in a web-accessible directory. A registered student session can upload and invoke a PHP script, executing code with the web server account's privileges.
