Mastering Metasploit - Third Edition

By: Nipun Jaswal

Overview of this book

We start by reminding you about the basic functionalities of Metasploit and its use in the most traditional ways. You’ll get to know about the basics of programming Metasploit modules as a refresher and then dive into carrying out exploitation as well building and porting exploits of various kinds in Metasploit. In the next section, you’ll develop the ability to perform testing on various services such as databases, Cloud environment, IoT, mobile, tablets, and similar more services. After this training, we jump into real-world sophisticated scenarios where performing penetration tests are a challenge. With real-life case studies, we take you on a journey through client-side attacks using Metasploit and various scripts built on the Metasploit framework. By the end of the book, you will be trained specifically on time-saving techniques using Metasploit.

Importing web-based RCE into Metasploit

In this section, we will look at how we can import web application exploits into Metasploit. Our entire focus throughout this chapter will be to grasp essential functions equivalent to those used in different programming languages. In this example, we will look at the PHP utility belt remote code execution vulnerability disclosed on 8 December 2015. The vulnerable application can be downloaded from: https://www.exploit-db.com/apps/222c6e2ed4c86f0646016e43d1947a1f-php-utility-belt-master.zip.

The remote code execution vulnerability lies in the code parameter of a POST request, which, when manipulated using specially crafted data, can lead to the execution of server-side code. Let's see how we can exploit this vulnerability manually as follows:

The command we used in the preceding screenshot is fwrite, which writes data to a file. We...
