0x1 前言

网上关于UACBypass方法比较多，本文备忘下COM方法的UACBypass的方法。在windows系统中，正常程序启动是user权限，如果需要提升到管理员权限，会弹出一个提权窗，给到用户确认是否要提权。但是windows系统中有很多系统程序，为了避免过多的打扰用户，所以windows对这些系统进程会有一些放过，本文备忘下在学习过程中整理的从user权限到管理员权限的COM方法的UACBypass，以及其提权的原理。

0x2 COM类提权

COM类提权原理，系统对提权类COM会校验调用来源，如果是系统可信进程（微软进程），则可以通过CoCreateInstanceAsAdmin函数来创建一个提权的COM类，如果不是可信进程，则CoCreateInstanceAsAdmin会弹出一个提权弹窗。对于校验可信进程，一般有多种方法：

1.注入到系统可信进程（一般注入到explorer、dllhost进行执行）

2.修改当前进程PEB结构，欺骗PSAPI，COM组件通过PSAPI读取进程PEB结构中的Commandline来识别进程来源是否可信，可以将进程的PEB路径修改为比如explorer.exe，就可以对COM提权

3.用可信文件直接调用COM组件，比如使用powershell.exe调用COM组件进行提权

下面介绍几种常用的提权COM类：

2.1 IFileOperation越权拷贝文件

通过修改PEB，越权执行IFileOperation的拷贝，参考 https://www.secpulse.com/archives/72563.html
