If you have MySQL command line client access:
Use a firewall to block port 3306 from the public internet. Use SSH tunneling or VPNs for remote administration.
Using responder or custom proxy to capture credentials:
use auxiliary/scanner/mysql/mysql_login set RHOSTS set USER_FILE /path/to/users.txt set PASS_FILE /path/to/passwords.txt run Use code with caution. 3. Post-Authentication Enumeration mysql hacktricks verified
When the FILE privilege is restricted, or when you need a more direct route to system command execution, User Defined Functions (UDFs) are the premier technique. UDFs allow you to create custom functions in C/C++ and compile them into shared libraries ( .so on Linux, .dll on Windows) that MySQL can load and execute.
Here are some popular tools for MySQL exploitation:
: Attempting to read local files through the client. If you have MySQL command line client access:
Securing or attacking a MySQL database requires a deep understanding of exploitation vectors, privilege escalation, and data exfiltration techniques. This comprehensive guide compiles verified methodologies from the cybersecurity community—inspired by HackTricks—to help you audit MySQL environments effectively. 1. Enumeration and Banner Grabbing
Begin with an aggressive Nmap scan to identify the exact service version, running scripts, and underlying operating system details: nmap -sV -sC -p 3306 Use code with caution. Banner Grabbing
The first step is to identify which users possess this powerful privilege: Here are some popular tools for MySQL exploitation:
If you only have SELECT / INSERT privileges, try:
Never leave the root password blank. Use long strings of letters, numbers, and symbols.
Gaining access to the MySQL console as a low-privilege user is just the beginning. To compromise the host machine, you need to escalate your database privileges or break out of the DBMS sandbox. Checking Current Privileges
