This extension provides a customizable payload generator, suitable for detecting a variety of file path vulnerabilities in file upload and download functionality:

  • File upload vulnerable to path traversal with the upload directory located inside the document root.
  • File upload vulnerable to path traversal with the upload directory outside the document root.
  • File upload not vulnerable to path traversal, but having the upload directory is inside of the document root, with no direct links to the uploaded file exposed by the application.
  • Local file inclusion/arbitrary file read vulnerable to path traversal with non-recurrent filters involved.
