COM组件相关的武器化开发技术

COM简介
由于网上关于直接调用windows内建com组件的编程技术比较稀少(至少我找了几天没找到)，该文会简要介绍如何通过已知clsid在自定可执行文件中调用windows com接口，实现部分武器化技术。
文旨在简单介绍调用windows本身com组件的相关编程技术，由于本人非职业开发，理解可能存在一定偏差，如发现有明显错误，请务必直接联系本人(防止误人子弟略略略略略)。
阅读本文的朋友很大概率经常使用诸如atexec、wmiexec之类的横向移动工具，该类技术其实质也是对dcom(分布式com)组件的调用。
com本身是一种开发理念，旨在跨应用和语言共享二进制代码，其理念类似dll，但dll仅能被C/C++理解或遵循C调用规范的语言使用,com通过指明二进制模块必须编译成约定的结构解决了这个问题，其实现方式与c++的类相似，所以通常使用c++来实现一个com组件。
就windows中实现来看，com组件本身仍旧是标准的pe结构(dll/exe)，只不过其内部包含了coclass，以及在注册表中注册了相关键值，以便我们找到并使用它。
原理
通常windows内建com已经在注册表内存储着相关信息，而自定义com需要创建注册表入口点告诉windows com组件服务器在上面位置，这个过程称之为注册(Registration)，我们可以在HKEY_CLASSES_ROOT\CLSID\{clsid}位置找到所有windows已注册的com组件。
注册后com通过GUID(globally unique identifier)唯一标识符来寻找并使用这个com组件，理论上每一个GUID(有时也称UUID)都是唯一的,GUID在标识不同的对象时会有不同的称呼，标识类对象时称之为CLSID(类标识符)、标识接口时被称为IID(接口标识符)。
在每一个注册的clsid表项中都包含一个名为InprocServer32的子项，该子项内存有映射到该com二进制文件的键值对，操作系统通过该键值对将com组件载入进程或另起进程。(进程内组件和进程外组件，二进制代码的表现形式为dll(内)和exe(外))。
我们可以通过以下powershell代码遍历所有com组件和它导出的方法。
New-PSDrive -PSProvider registry -Root HKEY_CLASSES_ROOT -Name HKCR
Get-ChildItem -Path HKCR:\CLSID -Name | Select -Skip 1 > clsids.txt
​
$Position  = 1
$Filename = "win10-clsid-members.txt"
$inputFilename = "clsids.txt"
ForEach($CLSID in Get-Content $inputFilename) {
      Write-Output "$($Position) - $($CLSID)"
      Write-Output "------------------------" | Out-File $Filename -Append
      Write-Output $($CLSID) | Out-File $Filename -Append
      $handle = [activator]::CreateInstance([type]::GetTypeFromCLSID($CLSID))
      $handle | Get-Member | Out-File $Filename -Append
      $Position += 1
}
通过C++实现调用
通常对com组件的利用很多文章都直接使用powershell代码调用接口，代码如下:
$handle = [activator]::CreateInstance([type]::GetTypeFromCLSID("xxx"))
$handle.shellxec('cmd.exe /c')
在这里我会介绍一种通过c++调用的方法，在介绍之前，先看一个简单的powershell案例，Charles Hamilton发现prchauto.dll拥有一个ProcessChain的类，该类公开的start方法和commdline属性。
接下来我们通过部分工具将这个简单案例使用c艹实现，我们先使用oleview打开这个com组件的实现文件。
可以看到processchain类导出了一个名为iprocesschain的接口，我们使用这个工具将这个类导出为IDL文件，然后使用MIDL工具将这个IDL文件转换成我们需要的C++的头文件，这个文件会定义这个类和接口的使用方法。
使用MIDL，生成的processchain.h就是我们需要的。
部分代码:
​
EXTERN_C const IID IID_IProcessChain;
​
#if defined(__cplusplus) && !defined(CINTERFACE)
    
    MIDL_INTERFACE("79ED9CB4-3A01-4ABA-AD3C-A985EE298B20")
    IProcessChain : public IDispatch
    {
    public:
        virtual /* [propget][id] */ HRESULT STDMETHODCALLTYPE get_ExecutablePath( 
            /* [retval][out] */ BSTR *ExecutablePath) = 0;
        
        virtual /* [propput][id] */ HRESULT STDMETHODCALLTYPE put_ExecutablePath( 
            /* [in] */ BSTR ExecutablePath) = 0;
        
        virtual /* [propget][id] */ HRESULT STDMETHODCALLTYPE get_CommandLine( 
            /* [retval][out] */ BSTR *CommandLine) = 0;
        
        virtual /* [propput][id] */ HRESULT STDMETHODCALLTYPE put_CommandLine( 
            /* [in] */ BSTR CommandLine) = 0;
        
        virtual /* [propget][id] */ HRESULT STDMETHODCALLTYPE get_NonBlocking( 
            /* [retval][out] */ VARIANT_BOOL *NonBlocking) = 0;
        
        virtual /* [propput][id] */ HRESULT STDMETHODCALLTYPE put_NonBlocking( 
            /* [in] */ VARIANT_BOOL NonBlocking) = 0;
        
        virtual /* [propget][id] */ HRESULT STDMETHODCALLTYPE get_TimeoutPeriod( 
            /* [retval][out] */ long *TimeoutPeriod) = 0;
        
        virtual /* [propput][id] */ HRESULT STDMETHODCALLTYPE put_TimeoutPeriod( 
            /* [in] */ long TimeoutPeriod) = 0;
        
        virtual /* [id] */ HRESULT STDMETHODCALLTYPE Start( 
            /* [out] */ VARIANT_BOOL *TimerFired) = 0;
        
        virtual /* [id] */ HRESULT STDMETHODCALLTYPE CancelWait( void) = 0;
        
        virtual /* [id] */ HRESULT STDMETHODCALLTYPE Terminate( void) = 0;
        
    };
接下来就是简单的编程实现了，如果我们能找到一个支持提权且能执行命令的com组件，那我们就又获得了一个新的bypassuac的方法。
