Remote code execution via spoofed upload type

Published Jan 2, 2026 · Updated Jan 2, 2026

Unrestricted file upload in Code Projects Content Management System 1.0 allows remote authenticated users to execute server-side scripts. The image handler in /admin/edit_posts.php trusts the multipart Content-Type value and stores a PHP file that remains web-accessible. Administrative access is required by the CNA assessment; successful exploitation executes code under the web server account.
