SQLMap Brief Introductory and Its Installation Steps

In our previous blog, we set up a lab Environment (SQLi-Labs) on behalf of SQL injection attacks.

Setting Up Lab Environment for SQL Injection

This tutorial guides you through setting up a lab environment for practicing SQL injection, a common web application vulnerability. It provides step-by-step instructions to configure the necessary software and create a safe environment for learning and testing SQL injection techniques.


In this chapter, we're going to learn different ways to exploit SQL injection attacks, using an Automated SQL injection and database takeover tool, called SQLMap.

SQLMap is a powerful, and versatile open-source tool written by Bernardo, and Miroslav to dynamically detect and exploit SQL injection issues. 

It supports many databases and helps us not only to enumerate and extract databases but also to execute system commands.

The tool supports the following list of underlying DBMS software used in various web applications—

  • MySQL, 
  • Oracle, 
  • PostgreSQL, 
  • Microsoft SQL Server, 
  • Microsoft Access, 
  • IBM DB2, 
  • SQLite, 
  • Firebird, 
  • Sybase, 
  • SAP MaxDB and 
  • HSQLDB. 

The main focus will be on the Linux/PHP/MySQL stack as it is still the most common web application stack we see these days. 

SQLMap contains a wide array of features some of which are the following: 

  • Support for different kinds of SQL injection techniques like: 
    • Error-based injection 
    • Blind injection 
    • Time-based injection 
    • Stacked queries 
  • Acting as a database client if appropriate credentials are provided 
  • Downloading and uploading files to the database server 
  • Ability to explore databases, tables, and columns individually Exploiting SQL Injection 
  • Built-in support for cracking common hashes such as MD5 
  • Support for the Metasploit framework 
  • Code execution by exploiting DBMS features such as xp_cmdshell


Using SQLMap


Kali Linux

SQL map comes pre-installed with Kali Linux, which is usually penetration testers' favorite operating system. 

You can launch the SQLMap Advanced help menu by executing the following command:

Any Linux Platform

If you want to install it on any other Linux Platform then run the following command:

mrdev@ubuntu:~$ cd sqlmap
mrdev@ubuntu:~$ ./sqlmap.py -h


Windows

If you wish to perform SQLMap command-line interface on your Windows machine, then our first priority is to download and install the python interpreter, as because SQLMap is written in python programming Language.

Download Python Installer

Once you have downloaded then install it. 

Check the Add python.exe to PATH and then Click on click on Install Now.

Once set up successfully, you can verify it by running Python on the command prompt.

Next, download the SQLMap Zip file from the official GitHub page. 

Download SQLMap.zip

Extract the Zip file:

Now change the directory to sqlmap-master directory, and then run the command prompt from here by typing cmd on the directory bar.


Now, from here, you can SQLMap as usual way. Let me test it by running help command:

If you want to run SQLMap directly from the Command prompt without changing the path, then you have to add the file path to the Environment variable.

Before that, we have to move the directory to the C:\ drive and then right-click on This PC, and then click on Properties. 

Here click on Advance system setting > Click on Environment variable > double click on Path variable and then add the file path of SQLMap.

Everything is ready! Now we can easily run SQLMap from the command prompt without switching the file path.
