CVE-2025-8859Public exploitNetwork attack vector

Code execution via unrestricted slider file upload

Published Aug 11, 2025 · Updated Aug 11, 2025

Unrestricted file upload in Code Projects eBlog Site 1.0 allows remote authenticated users to execute PHP through a slider image. The save-slider.php handler keeps the submitted filename extension and moves the file into the web-accessible uploads/slider directory without validating its content or type. An authenticated admin-panel session is required; an uploaded PHP payload can then run with the web server process's permissions.
