Kali Linux Web Penetration Testing Cookbook

By: Gilberto Najera-Gutierrez

Overview of this book

Web applications are a huge point of attack for malicious hackers and a critical area for security professionals and penetration testers to lock down and secure. Kali Linux is a Linux-based penetration testing platform and operating system that provides a huge array of testing tools, many of which can be used specifically to execute web penetration testing. This book will teach you, in the form step-by-step recipes, how to detect a wide array of vulnerabilities, exploit them to analyze their consequences, and ultimately buffer attackable surfaces so applications are more secure, for you and your users. Starting from the setup of a testing laboratory, this book will give you the skills you need to cover every stage of a penetration test: from gathering information about the system and the application to identifying vulnerabilities through manual testing and the use of vulnerability scanners to both basic and advanced exploitation techniques that may lead to a full system compromise. Finally, we will put this into the context of OWASP and the top 10 web application vulnerabilities you are most likely to encounter, equipping you with the ability to combat them effectively. By the end of the book, you will have the required skills to identify, exploit, and prevent web application vulnerabilities.

Using Tamper Data add-on to intercept and modify requests

Sometimes, applications have client-side input validation mechanisms through JavaScript, hidden forms, or POST parameters that one doesn't know or can't see or manipulate directly in the address bar; to test these and other kind of variables, we need to intercept the requests the browser sends and modify them before they reach the server. In this recipe, we will use a Firefox add-on called Tamper Data to intercept the submission of a form and alter some values before it leaves our computer.

How to do it...

  1. Go to Mantra's menu and navigate to Tools | Application Auditing | Tamper Data.

  2. Tamper Data's window will appear. Now, let's browse to We can see the requests section in the add-on populating:


    Every request we make in the browser will go through Tamper Data while it is active.

  3. To intercept a request and change its values, we need to start the tampering by clicking on Start Tamper. Start the tampering...
