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.

Using SQLMap to get database information


In Chapter 6, Exploitation – Low Hanging Fruits, we used SQLMap to extract information and the content of tables from a database. This is very useful but it is not the only advantage of this tool, nor the most interesting. In this recipe, we will use it to extract information about database users and passwords that may allow us access to the system, not only to the application.

How to do it...

  1. With the Bee-box virtual machine running and BurpSuite listening as a proxy, log in and select the SQL Injection (POST/Search) vulnerability.

  2. Enter any movie name and click Search.

  3. Now let's go to BurpSuite and check our request:

  4. Now, go to a terminal in Kali Linux and enter the following command:

    sqlmap -u "http://192.168.56.103/bWAPP/sqli_6.php" --cookie="PHPSESSID=15bfb5b6a982d4c86ee9096adcfdb2e0; security_level=0" --data "title=test&action=search" -p title --is-dba
    

    We can see a successful injection. That the current user is DBA which means that the user can...
