Authenticated code execution via unrestricted file upload

Published Sep 28, 2025 · Updated Sep 28, 2025

Unrestricted file upload in Projectworlds Online Tours and Travels 1.0 allows remote authenticated users to execute code via change-image.php. The handler accepts packageimage multipart data without restricting its filename, type, or content, allowing executable PHP to enter the web-accessible packageimages path. An administrator session is required, and successful exploitation creates a remotely reachable web shell on the server.
