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.

Password profiling with CeWL

With every penetration test, reconnaissance must include a profiling phase in which we analyze the application, department or process names, and other words used by the target organization. This will help us to determine the combinations that are more likely to be used when the need to set a user name or password comes to the personnel.

In this recipe, we will use CeWL to retrieve a list of words used by an application and save it for when we try to brute-force the login page.

How to do it...

  1. As the first step, we will look at CeWL's help to have a better idea of what it can do. In the terminal, type:

    cewl --help
  2. We will use CeWL to get the words on the WackoPicko application from vulnerable_vm. We want words with a minimum length of five characters; show the word count, and save the results to cewl_WackoPicko.txt:

    cewl -w cewl_WackoPicko.txt -c -m 5
  3. Now, we open the file that CeWL just created and see a list of "word count" pairs...
