Running commands remotely through an RDP connection

This question is a follow up of this one. I am trying to run a command through the command line on a remote machine running Windows 7 from a workstation running Debian in an SSH session on that machine. The setup is basically as follows:

debian box 1 === (SSH) ===> debian box 2 === (RDP) ===> Windows 7

I have tried running rdesktop from debian box 2:

rdesktop <Windows 7 box network address> -u username -p password -r disk:local="./TestRDP" -s "cmd.exe /K net use C: \\\\tsclient\local & C:\\test.bat & logoff"

but cmd.exe is not launched on the remote device. I have also tried to open up cmd.exe on its own:

rdesktop <Windows 7 box network address> -u username -p password -s "cmd.exe"

but the terminal is not launched upon login (rdesktop successfully connects through RDP).

I also tried using FreeRDP:

xfreerdp /u:user /p:password /app:"||cmd" /v:<Windows 7 box network address>

but this error was given upon executing cmd.exe:

RAIL exec error: execResult=RAIL_EXEC_E_NOT_IN_ALLOWLIST NtError=0x15

Reading this (dated) blog entry it is recommended that a registry key is added with the path to the binary (%windir%\System32\cmd.exe) but I cannot edit registry values on the remote machine.

This question suggests using windows remote shell and a third party rdp client to run the terminal on the remote windows machine. Are there any linux alternatives (aside from FreeRDP and rdesktop)?
