Web Pentesting with Editing Packets in Burpsuite

Web penetration testing involves evaluating the security of web applications by simulating attacks on them. Burp Suite is a popular tool used by web application security testers to intercept and modify network traffic to identify vulnerabilities in web applications.

One common technique used in web penetration testing is packet editing. This involves intercepting network traffic between the client and server using Burp Suite, and then modifying the packets to change the data being sent or to simulate different types of attacks. Here are the steps to perform packet editing using Burp Suite:

1. Set up Burp Suite: Install Burp Suite on your computer and configure it to intercept HTTP/HTTPS traffic.

2. Configure your browser to use Burp Suite as a proxy: In your browser settings, set up the proxy settings to use Burp Suite as a proxy.

3. Navigate to the web application you want to test: Enter the URL of the web application you want to test in your browser.

4. Intercept the packets: In Burp Suite, go to the "Proxy" tab and click the "Intercept" button. This will intercept all network traffic between your browser and the web application.

5. Modify the packets: Once the packets have been intercepted, you can modify them by clicking on them in the "Proxy" tab and then selecting the "Edit" option. This will allow you to change the contents of the packet, including the request headers, request body, response headers, and response body.

6. Test for vulnerabilities: Use packet editing to test for vulnerabilities in the web application, such as SQL injection or cross-site scripting (XSS). For example, you can modify the parameters of a request to see if the application is vulnerable to SQL injection attacks.

7. Save your changes: Once you have made your changes, you can save the modified packets by right-clicking on them in the "Proxy" tab and selecting the "Save item" option. This will allow you to save the packet as a file, which you can use for further analysis or to reproduce the attack.

Packet editing is just one of many techniques used in web penetration testing, but it can be a powerful tool for identifying vulnerabilities in web applications. However, it's important to use packet editing ethically and only on applications that you have permission to test.
