Notes
This PoC was tested on Windows 10 with Office Professional Plus 2016, version 1902. It will only work on 32-bit Office versions (on a 32 or 64-bit Windows version). If you have access to a 64-bit Office version and would like to contribute, please do!
The size of the original command line stored in originalCli needs to be greater than the size of the real one stored in cmdStr
