CloudFlare Bypass

Techniques

  • You can also use some service that gives you the historical DNS records of the domain. Maybe the web page is running on an IP address used before.

    • Same could be achieve checking historical SSL certificates that could be pointing to the origin IP address.

    • Check also DNS records of other subdomains pointing directly to IPs, as it's possible that other subdomains are pointing to the same server (maybe to offer FTP, mail or any other service).

  • If you find a SSRF inside the web application you can abuse it to obtain the IP address of the server.

  • Use Google cache: https://webcache.googleusercontent.com/search?q=cache:https://www.petsathome.com/shop/en/pets/dog

  • Use other cache services such as https://archive.org/web/
