SQL Injection Strategies

By: Ettore Galluccio, Edoardo Caselli, Gabriele Lombari

Overview of this book

SQL injection (SQLi) is probably the most infamous attack that can be unleashed against applications on the internet. SQL Injection Strategies is an end-to-end guide for beginners looking to learn how to perform SQL injection and test the security of web applications, websites, or databases, using both manual and automated techniques. The book serves as both a theoretical and practical guide to take you through the important aspects of SQL injection, both from an attack and a defense perspective. You’ll start with a thorough introduction to SQL injection and its impact on websites and systems. Later, the book features steps to configure a virtual environment, so you can try SQL injection techniques safely on your own computer. These tests can be performed not only on web applications but also on web services and mobile applications that can be used for managing IoT environments. Tools such as sqlmap and others are then covered, helping you understand how to use them effectively to perform SQL injection attacks. By the end of this book, you will be well-versed with SQL injection, from both the attack and defense perspective.

Chapter 2: Manipulating SQL – Exploiting SQL Injection

After dealing more generally with Structured Query Language (SQL) and its characteristics and peculiarities, we are now focusing more on the main crux of this book: the injection vulnerability. We've already seen, in a broader sense, what SQL injection is, and gave a glimpse of what could be done with it, and why.

In this chapter, as a follow-up to the previous one, we are continuing with the theoretical approach to the matter, getting more in touch with the practical aspects of SQL injection attacks. This chapter includes, in fact, examples of input strings that could be used for triggering SQL injection for many different purposes.

This chapter will lay the foundation for the practical part, which will instead focus on the execution of SQL injection attacks in a controlled setup, putting into practice what we will see in this part.

After discussing SQL injection with SQL syntax, this chapter will also...
