### ?? Introduction
MySQL is a widely used open-source relational database management system (RDBMS) that powers numerous web applications. As a penetration tester, it's crucial to identify vulnerabilities in MySQL to prevent unauthorized access to sensitive data. In this post, we'll explore the steps to conduct a penetration test on MySQL Port 3306.
### ???♂? Initial Reconnaissance
Before diving in, gather information about the target system using tools like Nmap to scan the target IP address and identify open ports.
```bash
nmap -sT 192.168.1.100
```
The output should reveal that port 3306 is open, indicating MySQL is running on the target system.
### ??? MySQL Version Scanning
Next, use Nmap to scan the MySQL version. The -sV option enables version detection.
```bash
nmap -sV 192.168.1.100 -p 3306
```
The output should display the MySQL version, helping identify potential vulnerabilities.
### ?? Authentication Bypass
Attempt to bypass authentication using the mysql command. Use the -h option to specify the target IP address and the -u option to specify the username.
```bash
mysql -h 192.168.1.100 -u root
```

If the password is not set or is weak, you might gain access to the MySQL database without authentication.
### ??? SQL Injection
SQL injection is a common vulnerability in web applications that use MySQL. Utilize tools like SQLMap to identify SQL injection vulnerabilities.
```bash
sqlmap -u "https://192.168.1.100/vulnerable.php?id=1" --dbms=mysql
```
SQLMap will attempt to inject SQL code to extract sensitive data from the database.
### ?? Brute Force Attack
If bypassing authentication or finding an SQL injection vulnerability fails, try a brute force attack using tools like Hydra.
```bash
hydra -l root -P /usr/share/wordlists/rockyou.txt 192.168.1.100 mysql
```
Hydra will attempt to guess the password using a dictionary attack.
### ?? Conclusion
We've demonstrated how to conduct a penetration test on MySQL Port 3306, covering initial reconnaissance, MySQL version scanning, authentication bypass, SQL injection identification, and brute force attacks. Always conduct penetration tests with permission and adhere to applicable laws and regulations.
Stay ethical, stay safe!
