Web Penetration Testing with Kali Linux - Third Edition

By: Gilberto Najera-Gutierrez, Juned Ahmed Ansari

Overview of this book

Web Penetration Testing with Kali Linux - Third Edition shows you how to set up a lab, helps you understand the nature and mechanics of attacking websites, and explains classical attacks in great depth. This edition is heavily updated for the latest Kali Linux changes and the most recent attacks. Kali Linux shines when it comes to client-side attacks and fuzzing in particular. From the start of the book, you'll be given a thorough grounding in the concepts of hacking and penetration testing, and you'll see the tools used in Kali Linux that relate to web application hacking. You'll gain a deep understanding of classicalSQL, command-injection flaws, and the many ways to exploit these flaws. Web penetration testing also needs a general overview of client-side attacks, which is rounded out by a long discussion of scripting and input validation flaws. There is also an important chapter on cryptographic implementation flaws, where we discuss the most recent problems with cryptographic layers in the networking stack. The importance of these attacks cannot be overstated, and defending against them is relevant to most internet users and, of course, penetration testers. At the end of the book, you'll use an automated technique called fuzzing to identify flaws in a web application. Finally, you'll gain an understanding of web application vulnerabilities and the ways they can be exploited using the tools in Kali Linux.

Crawling AJAX applications

In an AJAX-based application, the links that the crawler can identify depend on the application's logic flow. In this section, we will talk about three tools that can be used to crawl AJAX applications:

  • The AJAX Crawling Tool
  • Sprajax


As with any automated task, crawling AJAX applications must be carefully configured, logged, and monitored, as they may cause calls to unexpected functions and trigger undesired effects on the application, affecting the contents of the database, for example.

AJAX Crawling Tool

AJAX Crawling Tool (ACT) is used to enumerate AJAX applications. It can be integrated with web application proxies. Once crawled, the links are visible in the proxy interface. From there, you can test the application for vulnerabilities. To set up and use ACT, follow these instructions:

  1. Download the ACT from the following URL:

  1. After downloading ACT, start it from the bash shell using the following...
