Kali Linux Web Penetration Testing Cookbook - Second Edition

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 that provides a broad array of testing tools, many of which can be used to execute web penetration testing. Kali Linux Web Penetration Testing Cookbook gives you the skills you need to cover every stage of a penetration test – from gathering information about the system and application, to identifying vulnerabilities through manual testing. You will also cover the use of vulnerability scanners and look at basic and advanced exploitation techniques that may lead to a full system compromise. You will start by setting up a testing laboratory, exploring the latest features of tools included in Kali Linux and performing a wide range of tasks with OWASP ZAP, Burp Suite and other web proxies and security testing tools. As you make your way through the book, you will learn how to use automated scanners to find security ?aws in web applications and understand how to bypass basic security controls. In the concluding chapters, you will look at what you have learned in the context of the Open Web Application Security Project (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 this book, you will have acquired the skills you need to identify, exploit, and prevent web application vulnerabilities.

Identifying and exploiting blind SQL injections

We already saw how an SQLi vulnerability works. In this recipe, we will cover a different vulnerability of the same kind, one that does not show an error message or a hint that could lead us to the exploitation. We will learn how to identify and exploit a blind SQLi.

How to do it...

Log into DVWA and go to SQL Injection (Blind):

  1. The form looks exactly the same as the SQLi form we saw in the previous recipes. Type 1 in the textbox and click Submit to see the information about the user with the ID 1.
  1. Now, let's perform our first test with 1' and see whether we get an error as in previous recipes:

We get no error message, but no result either. Something interesting...
