1. Run COMahawk.exe
2. ???
3. Hopefully profit

or

1. COMahawk.exe "custom command to run" (ie. COMahawk.exe "net user /add test123 lol123 &")
2. ???
3. Hopefully profit

MSDN mentioned that only 1803 to 1903 is vulnerable to CVE-2019-1322. If it doesn't work, maybe it was patched.

However, it is confirmed that my 1903 does indeed have this bug so maybe it was introduced somewhere inbetween. YMMV.

Also, since you are executing from a service - you most likely cannot spawn any Window hence all command will be "GUI-less". Maybe different session? Idk, it is too late and I am tired haha.
