If an attacker gains low-privilege SQL injection or authentication credentials, MySQL 5.0.12 inherently allows the loading of arbitrary shared libraries via the CREATE FUNCTION syntax. Because early 5.0 releases lacked stringent checks on the plugin_dir system variable, attackers could write a malicious dynamic link library (DLL) or shared object (.so) file directly to the system and execute OS-level commands. 2.
