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.

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. An elementary example of a buffer overflow is shown in the following diagram:

The left side of the preceding diagram 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 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 the EIP (Instruction Pointer), 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 an exact number of bytes that are good enough to fill everything...
