CVE-2025-11353Public exploitNetwork attack vector

Remote code execution via extension-unchecked image upload

Published Oct 7, 2025 · Updated Oct 7, 2025

Unrestricted file upload in Code Projects Online Hotel Reservation System 1.0 allows remote attackers to execute PHP code. The /admin/addgalleryexec.php endpoint accepts a PHP filename when the upload begins with a PNG header, then stores it in an executable web directory. The proof of concept states that no login is required, while the CNA's CVSS assessments require low privileges; successful upload grants persistent server access.
