NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Unrestricted file upload vulnerability in Vesystem Cloud Desktop's /Public/webuploader/0.1.5/server/fileupload2.php. The 'file' argument can be manipulated to upload arbitrary files without proper validation, potentially allowing remote code execution.

MitigationDisable or restrict access to the vulnerable upload endpoint. Implement strict file type validation, whitelist allowed extensions, and store uploads outside web root. Consider WAF rules to block malicious file uploads.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Vesystem Cloud Desktop installation
    Locate the Vesystem Cloud Desktop installation directory on the server, typically found under the web root (e.g., /var/www/html, C:\inetpub\wwwroot, or similar). Look for the main application directories.
    Affected if The application is not found or is installed in a non-standard location that doesn't follow the web root structure.
  2. Verify vulnerable file exists
    Check for the presence of /Public/webuploader/0.1.5/server/fileupload2.php within the Vesystem installation directory. Use file system search or command: find /path/to/webroot -name 'fileupload2.php' -path '*/webuploader/0.1.5/*'
    Affected if The file fileupload2.php exists in the webuploader/0.1.5/server subdirectory.
  3. Confirm web server serves the upload endpoint
    Test network access to the /Public/webuploader/0.1.5/server/fileupload2.php endpoint by attempting an HTTP request (e.g., curl http://TARGET/Public/webuploader/0.1.5/server/fileupload2.php)
    Affected if The endpoint returns an HTTP response (200, 400, 405, or similar) indicating it is accessible via HTTP.
  4. Check if endpoint requires authentication
    Review web server configuration (Apache .htaccess, Nginx config, or application-level auth) and test the upload endpoint without credentials to determine if authentication is enforced.
    Affected if The upload endpoint accepts requests without requiring valid authentication credentials.

If Vesystem Cloud Desktop is installed, the vulnerable fileupload2.php exists in the webuploader/0.1.5 directory, and the upload endpoint is accessible without proper authentication, the environment is affected by CVE-2024-3804.
