🏗️ Install ⛏️ Usage 📡 Proxying HTTP Requests

Install

To install headerpwn, run the following command:

go install github.com/devanshbatham/[email protected]

Usage

headerpwn allows you to test various headers on a target URL and analyze the responses. Here's how to use the tool:

1. Provide the target URL using the -url flag.
2. Create a file containing the headers you want to test, one header per line. Use the -headers flag to specify the path to this file.

Example usage:

headerpwn -url https://example.com -headers my_headers.txt

• Format of my_headers.txt should be like below:

Proxy-Authenticate: foobar
Proxy-Authentication-Required: foobar
Proxy-Authorization: foobar
Proxy-Connection: foobar
Proxy-Host: foobar
Proxy-Http: foobar

Proxying requests through Burp Suite:

Follow following steps to proxy requests through Burp Suite:

• Export Burp's Certificate:

  • In Burp Suite, go to the "Proxy" tab.
  • Under the "Proxy Listeners" section, select the listener that is configured for 127.0.0.1:8080
  • Click on the "Import/ Export CA Certificate" button.
  • In the certificate window, click "Export Certificate" and save the certificate file (e.g., burp.der).

• Install Burp's Certificate:

  • Install the exported certificate as a trusted certificate on your system. How you do this depends on your operating system.
  • On Windows, you can double-click the .cer file and follow the prompts to install it in the "Trusted Root Certification Authorities" store.
  • On macOS, you can double-click the .cer file and add it to the "Keychain Access" application in the "System" keychain.
  • On Linux, you might need to copy the certificate to a trusted certificate location and configure your system to trust it.

You should be all set:

headerpwn -url https://example.com -headers my_headers.txt -proxy 127.0.0.1:8080
