27. How to configure Burp Suite with Firefox?
1. Open Burp Suite and click on start Temporary project.
2. Go to PROXY Tab and click proxy settings.
3. Look for the IP and port. By default it should be 127.0.0.1:8080.
4. Open Firefox and go to settings.
5. In settings search bar, search for PROXY.
6. Enter the details of local IP and Port to Manual Proxy.
7. Open a new tab and type https://burp and click on download CA Certificate.
8. Once it is downloaded, again go back to settings tab and search for certificate.
9. Then click on import and select the downloaded certificate.
10. Now, open a NEW TAB and open burp suite as well.
11. Turn on the intercept and type http://localhost. It must intercept it.
12. If it’s not intercepting, then go back to Firefox and in search bar type about:config and hit enter.
13. Then turn ON the network.proxy.allow_hijacking_localhost to TRUE.
14. Now, you’re all set.
15. Happy Hacking!

28. Interception of HTTP request

29. Sending Intercept to Intruder for Brute Force Attack

30. Creating wordlist for Brute Force Attack

31. Brute Force Successful

32. Command Injection
Try these commands:
1. Enter your local IP i.e. 127.0.0.1. Then hit enter.
2. Then type this “ 127.0.0.1;ls ”. If you’re seeing any message, carefully
observe it and look for any critical file of directory.
3. Then try this: “ 127.0.0.1; cat /etc/shadow/ ”, it may reveal password
directory, if available.
4. Try this if previous one didn’t worked: “ ;cat /etc/passwd ”.
5. You can also try this to find the username: “ ;whoami ”.
