  3. Use xssless to generate your payload: ./xssless.py burp_export_file
  4. Pwn!
A more detailed tutorial can be found here


  • Automated XSS payload generation from imported Burp proxy requests
  • Payloads are 100% asynchronous and won't freeze the user's browser
  • CSRF tokens can be easily extracted and set via the -p option
  • POST multipart is supported, along with XSS file uploading via the -f option
  • Payloads are dynamic and portable (due to relative URLs)
  • Crazy JavaScript worms with no hassle!
