-- Enumerate all tables Union Select 1,2,3,4,group_concat(0x7c,table_name,0x7C) from information_schema.tables -- Enumerate columns of a specific table Union Select 1,2,3,4,column_name from information_schema.columns where table_name="<TABLE NAME>"

The MySQL information stored in the information_schema database is a goldmine for an attacker. In the context of a web application, SQL injection (SQLi) can be used to systematically extract all of this schema data, even in the most restrictive blind conditions.

Run arbitrary operating system commands with the privileges of the MySQL service account: SELECT sys_eval('id'); SELECT sys_eval('whoami'); Use code with caution. 6. Defensive Hardening Best Practices

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 This link or copies made by others cannot be deleted

: Vulnerabilities like LOAD_FILE() can be used to read local files or initiate network requests (SSRF), provided the secure_file_priv global variable is properly configured. Security Recommendations

Exploiting insecure defaults & exposed ports Try again later

: Using /*! 40110 and 1=0*/ to fingerprint versions or hide code from simple filters.

If secure_file_priv is empty or a world-writeable path, you have file write potential.

Use nmap -sV -p 3306 to identify the specific version, as many exploits are version-dependent.

This comprehensive guide compiles verified penetration testing methodologies, enumeration tactics, and exploitation vectors for MySQL environments, aligned with industry-standard HackTricks methodologies. 1. Initial Reconnaissance and Port Scanning
