Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate PHP F1 Max's File Uploader installationSearch the web server document root for files named 'upload.php', 'file_uploader.php', 'f1_max_upload.php', or directories containing 'f1' and 'upload' in their names. Check common paths like /uploads/, /upload/, or /cgi-bin/ for this specific script.Affected if The PHP F1 Max's File Uploader script is found on the server
-
Verify the upload form exists and is accessibleIf the script is found, confirm it exposes a web-accessible form for file uploads by accessing the URL directly (e.g., http://target/upload.php) and checking if an HTML form with enctype='multipart/form-data' is present.Affected if The file upload form is accessible via HTTP and accepts file input
-
Check for server-side file type validationExamine the upload script source code (e.g., upload.php) for validation logic. Look for checks on $_FILES['userfile']['type'], getimagesize(), magic byte validation, or file extension whitelisting. Search for conditions that reject non-allowed file types.Affected if No server-side validation of file content, type, or extension is present in the code
-
Inspect upload directory script execution settingsCheck the web server configuration (Apache .htaccess, Nginx config) or PHP configuration (php.ini disable_functions) for the upload directory. Verify if script execution is allowed for uploaded files. Look for 'AddType application/x-httpd-php' or similar directives in the upload folder.Affected if Uploaded files can be executed as PHP scripts (e.g., .php files are not blocked, no security headers like Content-Disposition are enforced)
-
Determine if uploads are stored inside web rootReview the upload script to see the $upload_path or destination directory. Check if uploaded files are stored in a path accessible via web browser (inside document root) versus outside the web root.Affected if Uploaded files are stored within the web-accessible document root
The system is affected if PHP F1 Max's File Uploader is installed and accessible, with no server-side validation of uploaded file types/content and uploaded files stored in a web-accessible directory where they can be executed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict server-side validation of file types using magic byte checking, rename uploaded files, store uploads outside the web root, and disable script execution in the upload directory.
