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 different ways in which web applications perform user authentication to restrict access to privileged resources or sensitive information and looked at how the session is maintained, given that HTTP doesn't have a built-in session management functionality. The most common approaches for doing this in today's web applications are form-based authentication and session IDs sent in cookies.

We also examined the most common security failure points in authentication and session management, how attackers can exploit them using built-in browser tools, or through other tools included in Kali Linux, such as Burp Suite, OWASP ZAP, and THC Hydra.

In the last section, we discussed some best practices that may prevent or mitigate authentication and session management flaws by requiring authentication for all privileged components of the application using complex, random session IDs and enforcing a strong password policy. These are some of the most important preventative...
