Payload injection: failure when injecting powershell

[lubiedo]

Info

Branch: master
Command line:

$ pyrdp-mitm.py --payload-powershell-file payload.ps1  --payload-delay 10000 --payload-duration 1000 [REDACTED]

Windows version: Server 2016 Datacenter

Issue:

Fix:

A simple fix would be to use ; instead of & here:

pyrdp/pyrdp/mitm/RDPMITM.py

Line 434 in 4cafde0

return self.attacker.sendText(self.config.payload + " & exit")

This way we will ignore the output and just execute the exit.

Did you git blame for why it was an ampersand to begin with? AFAIK & is not even valid on cmd, it should've been &&
