Metasploit Revealed: Secrets of the Expert Pentester

By: Sagar Rahalkar, Nipun Jaswal

Overview of this book

Metasploit is a popular penetration testing framework that has one of the largest exploit databases around. This book will show you exactly how to prepare yourself against the attacks you will face every day by simulating real-world possibilities. This learning path will begin by introducing you to Metasploit and its functionalities. You will learn how to set up and configure Metasploit on various platforms to create a virtual test environment. You will also get your hands on various tools and components and get hands-on experience with carrying out client-side attacks. In the next part of this learning path, you’ll develop the ability to perform testing on various services such as SCADA, databases, IoT, mobile, tablets, and many 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. The final instalment of your learning journey will be covered through a bootcamp approach. You will be able to bring together the learning together and speed up and integrate Metasploit with leading industry tools for penetration testing. You’ll finish by working on challenges based on user’s preparation and work towards solving the challenge. The course provides you with highly practical content explaining Metasploit from the following Packt books: 1. Metasploit for Beginners 2. Mastering Metasploit, Second Edition 3. Metasploit Bootcamp

Exploiting stack-based buffer overflows with Metasploit

The buffer overflow vulnerability is an anomaly where, while writing data to the buffer, it overruns the buffer size and overwrites the memory addresses. A very simple example of buffer overflow is shown in the following diagram:

The left side of the preceding screenshot shows what an application looks like. However, the right side denotes the application's behavior when a buffer overflow condition is met.

So, how can we take an advantage of buffer overflow vulnerability? The answer is straightforward. If we know the exact amount of data that will overwrite everything just before the start of EIP, we can put anything in the EIP and control the address of the next instruction to be processed. Therefore, the first thing is to figure out exact number of bytes that are good enough to fill everything before the start of the EIP. We will see in the upcoming sections how can we find the exact number of bytes using Metasploit utilities.
