Kali Linux Web Penetration Testing Cookbook

By: Gilberto Najera-Gutierrez

Overview of this book

Web applications are a huge point of attack for malicious hackers and a critical area for security professionals and penetration testers to lock down and secure. Kali Linux is a Linux-based penetration testing platform and operating system that provides a huge array of testing tools, many of which can be used specifically to execute web penetration testing. This book will teach you, in the form step-by-step recipes, how to detect a wide array of vulnerabilities, exploit them to analyze their consequences, and ultimately buffer attackable surfaces so applications are more secure, for you and your users. Starting from the setup of a testing laboratory, this book will give you the skills you need to cover every stage of a penetration test: from gathering information about the system and the application to identifying vulnerabilities through manual testing and the use of vulnerability scanners to both basic and advanced exploitation techniques that may lead to a full system compromise. Finally, we will put this into the context of OWASP and the top 10 web application vulnerabilities you are most likely to encounter, equipping you with the ability to combat them effectively. By the end of the book, you will have the required skills to identify, exploit, and prevent web application vulnerabilities.

Obtaining SSL and TLS information with SSLScan


We, at a certain level, used to assume that when a connection uses HTTPS with SSL or TLS encryption, it is secured and any attacker that intercepts it will only receive a series of meaningless numbers. Well, this may not be absolutely true; the HTTPS servers need to be correctly configured to provide a strong layer of encryption and protect users from MiTM attacks or cryptanalysis. A number of vulnerabilities in implementation and design of SSL protocol have been discovered; thus, making the testing of secure connections mandatory in any web application penetration test.

In this recipe, we will use SSLScan, a tool included in Kali Linux, to analyze the configuration (from the client's perspective) of the server in terms of its secure communication.

How to do it...

  1. OWASP BWA virtual machine has already configured the HTTPS server, to be sure that it works right go to https://192.168.56.102/, if the page doesn't load normally, you may have to check...
