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.

Abusing file inclusions and uploads


As we saw in Chapter 4, Finding Vulnerabilities, file inclusion vulnerabilities occur when developers use poorly validated input to generate file paths and use those paths to include source code files. Modern versions of server-side languages, such as PHP since 5.2.0, have by default disabled the ability to include remote files, so it has been less common to find an RFI since 2011.

In this recipe, we will first upload a couple of malicious files, one of them is a webshell (a web page capable of executing system commands in the server), and then execute them using local file inclusions.

Getting ready

We will use Damn Vulnerable Web Application (DVWA) in the vulnerable_vm for this recipe and will have it with a medium level of security, so let's set it up:

  1. Navigate to http://192.168.56.102/dvwa.

  2. Log in.

  3. Set the security level to medium: Go to DVWA Security, select medium in the combo box and click on Submit.

We will upload some files to the server, but you need...
