Based on POC and description we just need to create a simple mcl file contains our executable path and preso it works.
The caveat for this attack is that you cannot passed an argument such as cmd.exe /c ipconfig in the mcl file. However we can execute our payload externally via UNC PATH provided by a simple SMB Server. The steps required.
1. Generate evil payload exe
2. Setup a SMB Listener
3. Create MCL file that points to evil payload.
4. Profits.
I use Impacket SMB Server to simulate the steps above. If you are a bit creative, we can use DLL Hijacking Method to cloak our payload .
Better patch it up fast.
