SQL Injection
SQL Injection using SQLmap
SQLMap Tutorial
Welcome to our comprehensive SQLMap tutorial, where you will learn how to use SQLMap for database penetration testing and explore various aspects of SQL injection.
What is SQLMap?
SQLMap is an open-source penetration testing tool that automates the process of detecting and exploiting SQL injection vulnerabilities in web applications. It helps security professionals identify and fix potential security weaknesses.

1. Introduction to SQL Injection
SQL injection is a common web application vulnerability that allows attackers to manipulate an application's database by injecting malicious SQL queries. In this section, you will learn the basics of SQL injection, its types, and how attackers exploit it.
2. Installing SQLMap
Before you can use SQLMap, you need to install it on your system. We'll walk you through the installation process on various platforms, including Windows, Linux, and macOS.
3. Basic Usage
Learn how to perform basic SQL injection tests using SQLMap. We'll cover the essential commands and options you need to get started. Additionally, we'll demonstrate how to identify vulnerabilities and extract data from the database.
SQLMap Basic Options
| Option | Description |
|---|---|
-r |
This option specifies the location of a file containing HTTP request data. |
-u URL |
Specify the target URL for testing. |
--crawl INT |
Crawl target recursivly with option of how many levels deep to crawl |
--forms |
Scan the target website to identify and test HTML forms for potential SQL injection vulnerabilities. |
-p PARAMETER |
Define the vulnerable parameter to exploit. |
-r |
This option specifies the location of a file containing HTTP request data. |
-u URL |
Specify the target URL for testing. |
--dbs |
List databases on the target server. |
--tables |
List tables in a specific database. |
--dump |
Dump data from a specific table. |
4. Advanced Usage
Explore advanced features and techniques for more complex SQL injection scenarios. Discover how to customize your tests, evade security measures, and escalate privileges. We'll cover various payloads, tamper scripts, and post-exploitation tasks.
Advanced SQLMap Options
| Option | Description |
|---|---|
-D database |
Specify the name of the database to target. |
-T table |
Use this option to specify the name of the database table to target. |
-C column |
Specify the name of the column within the targeted table for SQLMap to focus on. |
--level |
Set the level of tests to perform (1-5). |
--risk |
Set the risk factor of tests (1-3). |
--tamper |
Use tamper scripts to obfuscate payloads. |
--os-shell |
Get an interactive operating system shell. |
--priv-esc |
Perform privilege escalation. |
5. Preventing SQL Injection
It's crucial to understand how to protect your web applications from SQL injection attacks. In this section, we'll discuss best practices, security measures, and coding techniques to prevent SQL injection vulnerabilities. Learn how to sanitize input, use prepared statements, and implement web application firewalls (WAFs).
