Online Hotel Reservation System CVE-2025-11352

Primary remediation requires applying a security patch from the vendor; however, no patched version is currently identified in the provided references. Organizations should immediately contact code-projects through https://code-projects.org/ to request a security update or confirmation of availability. As an interim compensating control, restrict access to /admin/addexec.php and the /admin/ directory to trusted IP addresses only via web server configuration (e.g., Apache .htaccess or nginx location block), and configure the upload directory with execute permissions explicitly disabled (e.g., chmod 644, or add .htaccess with 'php_flag engine off'). Additionally, implement strict file type validation at the application level by whitelisting only image MIME types (image/jpeg, image/png, image/gif) and enforcing server-side verification via file magic bytes rather than extension checking. If administratively feasible, generate audit logs for all file uploads to /admin/addexec.php and monitor for unexpected file types or sizes. These controls trade ease of administration for security; verify that legitimate admin workflows are not disrupted by IP restrictions before deployment.
