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.

In this chapter, we reviewed some of the vulnerabilities in web applications that may escape the spotlight of XSS, SQL injection, and other common flaws. As a penetration tester, you need to know how to identify, exploit, and mitigate vulnerabilities so that you can seek them out and provide proper advice to your clients.

We began this chapter by covering the broad concept of insecure direct object references and some of its variants. Then we moved on to file inclusion vulnerabilities, which are a special type of insecure direct object reference, but represent a classification category by itself. We did an exercise on LFI and explained the remote version.

After that, we reviewed how different servers process duplicated parameters in requests and how this can be abused by an attacker through HTTP parameter pollution.

Next, we looked at information disclosure, and we reviewed examples presented to illustrate how applications can present too much information to users and how that information...
