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.

Chapter 10. Other Common Security Flaws in Web Applications

So far in this book, we have covered most of the issues surrounding web application security and penetration testing, albeit briefly. However, due to the nature of web applications—which represent such a mixture of diverse technologies and methodologies that do not always work well together—the number of specific vulnerabilities and different types of attacks targeting these applications is so large and rapidly changing that no single book could possibly cover everything; hence, some things must be left out.

In this chapter, we will cover a diverse set of vulnerabilities commonly present in web applications that sometimes escape the focus of developers and security testers, not because they are unknown (in fact, some are in OWASP Top 10), but because their impact is sometimes underestimated in real-world applications, or because vulnerabilities such as SQL injection and XSS are much more relevant because of their direct impact on...
