IP Spoofing (Bypass Whitelisting)

Audit Guideline

  1. Try to access the application from any network except the whitelisted one.
  2. Capture the base request in the burp community and send the request to the repeater.
  3. Add X-Forwarded-For in the request and the IP that has whitelisted for application access.
  4. Observe the application will respond normally. Hence, bypassed the whitelisting to access the application.

  2. Add one more Host Header with the custom domain as a value in the request and send the request.
  3. Observe the victim will get the password reset mail having a link with a custom domain and the token. Once the victim clicks on the link, the attacker will get the link in his web logs.
