If INTO OUTFILE is blocked, use MySQL logs:
Every executed SQL statement is written to the log file. After injection, the log file functions as a fully‑fledged webshell.
Place phpMyAdmin behind a Virtual Private Network (VPN) or restrict access to specific, whitelisted IP addresses using web server configurations (e.g., .htaccess or Nginx allow directives).
HackTricks notes that many admins leave default credentials, especially in development or forgotten instances. A simple root with no password often works. Alternatively, credentials might have been previously leaked via: phpmyadmin hacktricks
POST /phpMyAdmin/?-d+allow_url_include%3d1+-d+auto_prepend_file%3dphp://input HTTP/1.1 Host: target.com
If phpMyAdmin is not on the root domain, network scanners frequently look for it at these common endpoints: /phpmyadmin/ /phpMyAdmin/ /pma/ /admin/phpmyadmin/ /db/phpmyadmin/ 2. Authentication Bypass and Credential Hunting
Similar to general log injection but uses the slow query log. Enable it with: If INTO OUTFILE is blocked, use MySQL logs:
: Enable PMA's built-in 2FA support.
Affected versions 4.x (prior to 4.9.4) and 5.x (prior to 5.0.1). The application failed to sanitize the username field on the User Accounts page, allowing an authenticated user to scale database privileges.
Check $cfg['AllowArbitraryServer'] = true; in config.inc.php – allows attacker to connect to external MySQL servers. HackTricks notes that many admins leave default credentials,
4.1. Discovery & Reconnaissance
The %253f is decoded in two stages to ? , effectively stripping everything after the ? and leaving db_sql.php , which is whitelisted.
The primary attack vectors can be summarized into three categories:
7.1. Network-Level Controls
Unlike a blind SQL injection vulnerability—which requires writing custom scripts, dealing with WAFs, and painstakingly extracting data one character at a time—phpMyAdmin offers a . From an attacker’s perspective, this is equivalent to finding an unlocked backdoor into the server room.
