In this chapter, we are going to study SQL Injection (SQLi) vulnerabilities. To gain insight into these vulnerabilities, we will first learn about SQL, look at the reasons why we are studying SQL, and how
dangerous SQLi is exactly. Moving ahead, we will learn some techniques to discover SQL injections. Then, we will learn how we can bypass SQLi authorization and how to discover SQLi using the GET method. We will also see how we can work around SQL commands and discover tables using commands. In the loadfile section, we will see how we can implement SQLi on server files. Then, we are going to learn how we can use a tool called sqlmap. Finally, will look at techniques we can use to prevent dangerous SQL injections.
In this chapter, we'll cover the following topics:
- What is SQL?
- The dangers of SQLi
- Discovering SQLi
- SQLi authorization bypass
