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.

Attacking traditional web applications– manual techniques

Let's begin with manual attacks against OWASP BWA web applications. We already found, in Chapter 2, Manipulating SQL – Exploiting SQL Injection, an easy attack point for extracting information through SQL injection, but we will pretend that each application is independent and does not share the same instance of MySQL. For this reason, we will not consider the OWASP Vicnum application for this purpose, as it would make things too easy for us. Each application will be considered as a separate target so that we can explore the intrinsic vulnerabilities residing in them. In this section, we will perform SQL attacks against three of the OWASP BWA applications: Mutillidae II, Magical Code Injection Rainbow, and Peruggia, putting in practice what you have learned so far in a guided setting.

Attacking Mutillidae II

Our first target is kind of a warm-up—Mutillidae II is an application designed to provide...
