Win95+IE3 – Win10+IE11全版本执行漏洞
微软本月安全更新修复了一个潜藏了18年的IE远程代码执行漏洞（CVE-2014-6332），可以说是给windows吃了一颗大补丸。缺陷出现在VBScript的代码中，自Windows 95首次发布（19年前）以来就一直存在。详情点我
Metasploit Framework下的利用测试
所有IE版本通杀，但是由于msf中自带的exp中调用的是 powershell，所以msf（Metasploit Framework）中的exp代码只对安装powershell的系统生效。我们这里测试受害的机器为windows2008.
本站提供安全工具、程序(方法)可能带有攻击性，仅供安全研究与教学之用，风险自负!

代码导入Metasploit Framework
在kali系统中，把上面源码复制到下面文件中。
vim /usr/share/metasploit-framework/modules/exploits/windows/browser/ms14_064_safemodedisable.rb
利用测试
在windows2008上用IE访问链接。
