mysql-info : Fetches protocol version, thread ID, status flags, and capabilities.
If credentials are not known, verify for common weak configurations: Empty Passwords: Connect using mysql -u root (many default installs lack a root password). Hash Extraction:
MySQL typically listens on . However, non-standard ports are frequently used to obscure the service.
On certain Linux distributions, a verified vulnerability allowed attackers to bypass authentication by repeatedly attempting to log in with an incorrect password. Due to a casting error, there was a 1 in 256 chance the server would accept the wrong password as correct. 5. Post-Exploitation and Lateral Movement Enumerating Users : Extracting hashes from mysql.user Sensitive Data Discovery
Use a firewall to block port 3306 from the public internet. Use SSH tunneling or VPNs for remote administration. mysql hacktricks verified
When an empty password is not permitted, use automated tools to test for weak or default credentials (e.g., root:root , root:password , root:admin ).
I can provide specific or remediation steps based on those details.
: Query the mysql.user table to harvest password hashes. Use Hashcat with mode 300 (MySQL4.1/MySQL5) or mode 200 (MySQL3.23) to crack them off-line.
Server‑Side Request Forgery (SSRF) combined with the gopher:// protocol is a powerful MySQL attack vector. If an SSRF‑vulnerable endpoint can make requests to internal ports (e.g., ), an attacker can forge a full MySQL handshake. mysql-info : Fetches protocol version, thread ID, status
This command attempts to read the initial handshake packet, which often leaks: The exact MySQL server version.
CREATE FUNCTION sys_eval RETURNS STRING SONAME 'lib_mysqludf_sys.so'; Use code with caution.
Securing a MySQL deployment requires hardening both the network layer and the internal database configurations.
Once internal access is granted, executing internal enumeration helps map out privileges and find sensitive data. Basic System Information However, non-standard ports are frequently used to obscure
: Executing system commands with the privileges of the user running the MySQL service (often C. Exploiting the "Old Passwords" Vulnerability
-- Kill connection KILL CONNECTION 123;
MySQL is one of the most widely deployed relational database management systems in the world. Consequently, it is a primary target for penetration testers and malicious actors alike.
