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.

HTML5 for penetration testers

The latest version of the HTML standard comes with many new features that may help the developers prevent security flaws and attacks on their applications. However, it also poses new challenges for the design and implementation of new functionality, which may lead to applications opening up new and unexpected opportunities to attackers due to the use of not-yet-fully understood new technology.

In general, penetration testing an HTML5 application is no different than testing any other web application. In this section, we will cover some of the key features of HTML5, their implication for penetration testing, and some ways that applications implementing these features can be attacked.

New XSS vectors

Cross-Site Scripting (XSS) is a major issue in HTML5 applications, as JavaScript is used to interact with all of the new features from client-side storage to WebSockets to Web Messaging.

Also, HTML includes new elements and tags that may be used as attack vectors for...
