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.

Watching the source code

Looking into a web page's source code allows us to understand some of the programming logic, detect the obvious vulnerabilities, and also have a reference when testing, as we will be able to compare the code before and after a test and use that comparison to modify our next attempt.

In this recipe, we will view the source code of an application and arrive at some conclusions from that.

Getting ready

For this recipe, start the vulnerable_vm.

How to do it...

  1. Browse to

  2. Select the WackoPicko application.

  3. Right-click on the page and select View Page Source. A new window with the source code of the page will open:

    With the source code we can discover the libraries or external files that the page is using and where the links go. Also, as can be seen in the preceding image, this page has some hidden input fields. The selected one is MAX_FILE_SIZE; this means that, when we are uploading a file, this field determines the maximum size allowed for the file we...
