How to Bypass WAF Using SQLMAP on GNU/Linux

Jun 21, 2024 | Programming

Welcome to your ultimate guide on bypassing Web Application Firewalls (WAF) using SQLMAP on a GNU/Linux system. This process may sound intimidating, but with the right guidance, you’ll be navigating through WAF barriers like a seasoned pro. Let’s decode the craft of SQL injection and how SQLMAP can assist you without breaking a sweat!

What is SQLMAP?

SQLMAP is an open-source penetration testing tool that automates the process of detecting and exploiting SQL injection vulnerabilities in web applications. Think of it as your trusty Swiss Army knife, equipped to handle various database types, whether they’re MySQL or PostgreSQL, and adept at bypassing WAF obstacles as well.

Steps to Bypass WAF Using SQLMAP

  • Install SQLMAP: Ensure you have SQLMAP installed on your GNU/Linux system. You can clone the repository using Git:
  • git clone https://github.com/sqlmapproject/sqlmap.git
  • Navigate to the SQLMAP directory: Change into the directory of your cloned SQLMAP.
  • cd sqlmap
  • Identifying the Target URL: Find the URL that you want to test vulnerabilities on. This should be a URL that you legally have permission to test.
  • Generate Request: You can generate a request using a tool like Burp Suite, which captures HTTP requests. Make sure you have the request saved or noted.
  • Run SQLMAP: Use the following command pattern to launch SQLMAP and specify the target URL and any WAF bypass techniques:
  • python sqlmap.py -u "http://target.url/path?param=value" --tamper=space2comment

Understanding the Command

Now, let’s break down the command with an analogy. Imagine you are a courier delivering a package. The URL is your destination address, the –tamper=space2comment is an alternative route that allows you to evade toll booths (WAF), and SQLMAP acts as your delivery truck, equipped with all the tools you need to complete the delivery (in this case, detecting SQL injections).

Troubleshooting Common Issues

If you encounter any issues while using SQLMAP, here are some troubleshooting tips:

  • **Check Your Installation:** Ensure SQLMAP is correctly installed and updated to the latest version. Sometimes, an outdated version can lead to unforeseen errors.
  • **Modify Tamper Scripts:** If you face blocks by the WAF, try experimenting with different tamper scripts or combinations for your requests. SQLMAP offers various tamper scripts designed specifically for bypassing WAFs.
  • **Network Issues:** Confirm your network connection is stable. A shaky connection can interrupt communication with the target server.
