Ruby on Rails Rails 3.1.10

SQL injection vulnerability in activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb in the PostgreSQL adapter for Active Record in Ruby on Rails 2.x and 3.x before 3.2.19 allows remote attackers to execute arbitrary SQL commands by leveraging improper bitstring quoting.

actionpack/lib/action_dispatch/http/request.rb in Ruby on Rails before 3.2.16 and 4.x before 4.0.2 does not properly consider differences in parameter handling between the Active Record component and the JSON implementation, which allows remote attackers to bypass intended database-query restrictions and perform NULL checks or trigger missing WHERE clauses via a crafted request that leverages (1) third-party Rack middleware or (2) custom Rack middleware. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-0155.

The Active Record component in Ruby on Rails 2.3.x, 3.0.x, 3.1.x, and 3.2.x does not ensure that the declared data type of a database column is used during comparisons of input values to stored values in that column, which makes it easier for remote attackers to conduct data-type injection attacks against Ruby on Rails applications via a crafted value, as demonstrated by unintended interaction between the "typed XML" feature and a MySQL database.

Cross-site scripting (XSS) vulnerability in Action View in Ruby on Rails 3.x before 3.2.22.3, 4.x before 4.2.7.1, and 5.x before 5.0.0.1 might allow remote attackers to inject arbitrary web script or HTML via text declared as "HTML safe" and used as attribute values in tag handlers.

The ActiveSupport::XmlMini_JDOM backend in lib/active_support/xml_mini/jdom.rb in the Active Support component in Ruby on Rails 3.0.x and 3.1.x before 3.1.12 and 3.2.x before 3.2.13, when JRuby is used, does not properly restrict the capabilities of the XML parser, which allows remote attackers to read arbitrary files or cause a denial of service (resource consumption) via vectors involving (1) an external DTD or (2) an external entity declaration in conjunction with an entity reference.

actionpack/lib/action_view/lookup_context.rb in Action View in Ruby on Rails 3.x before 3.2.16 and 4.x before 4.0.2 allows remote attackers to cause a denial of service (memory consumption) via a header containing an invalid MIME type that leads to excessive caching.

actionpack/lib/action_view/template/text.rb in Action View in Ruby on Rails 3.x before 3.2.17 converts MIME type strings to symbols during use of the :text option to the render method, which allows remote attackers to cause a denial of service (memory consumption) by including these strings in headers.

Directory traversal vulnerability in actionpack/lib/action_dispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.21, 4.0.x before 4.0.12, 4.1.x before 4.1.8, and 4.2.x before 4.2.0.beta4, when serve_static_assets is enabled, allows remote attackers to determine the existence of files outside the application root via vectors involving a \ (backslash) character, a similar issue to CVE-2014-7818.

The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method.

Multiple cross-site scripting (XSS) vulnerabilities in actionview/lib/action_view/helpers/number_helper.rb in Ruby on Rails before 3.2.17, 4.0.x before 4.0.3, and 4.1.x before 4.1.0.beta2 allow remote attackers to inject arbitrary web script or HTML via the (1) format, (2) negative_format, or (3) units parameter to the (a) number_to_currency, (b) number_to_percentage, or (c) number_to_human helper.

Directory traversal vulnerability in actionpack/lib/action_dispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.20, 4.0.x before 4.0.11, 4.1.x before 4.1.7, and 4.2.x before 4.2.0.beta3, when serve_static_assets is enabled, allows remote attackers to determine the existence of files outside the application root via a /..%2F sequence.

Cross-site scripting (XSS) vulnerability in the number_to_currency helper in actionpack/lib/action_view/helpers/number_helper.rb in Ruby on Rails before 3.2.16 and 4.x before 4.0.2 allows remote attackers to inject arbitrary web script or HTML via the unit parameter.

The sanitize_css method in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle \n (newline) characters, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via crafted Cascading Style Sheets (CSS) token sequences.

ActiveRecord in Ruby on Rails before 2.3.17, 3.1.x before 3.1.11, and 3.2.x before 3.2.12 allows remote attackers to bypass the attr_protected protection mechanism and modify protected model attributes via a crafted request.

Cross-site scripting (XSS) vulnerability in actionpack/lib/action_view/helpers/translation_helper.rb in the internationalization component in Ruby on Rails 3.x before 3.2.16 and 4.x before 4.0.2 allows remote attackers to inject arbitrary web script or HTML via a crafted string that triggers generation of a fallback string by the i18n gem.

The sanitize helper in lib/action_controller/vendor/html-scanner/html/sanitizer.rb in the Action Pack component in Ruby on Rails before 2.3.18, 3.0.x and 3.1.x before 3.1.12, and 3.2.x before 3.2.13 does not properly handle encoded : (colon) characters in URLs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted scheme name, as demonstrated by including a : sequence.
