The Authlogic gem for Ruby on Rails, when used with certain versions before 3.2.10, makes potentially unsafe find_by_id method calls, which might allow remote attackers to conduct CVE-2012-6496 SQL injection attacks via a crafted parameter in environments that have a known secret_token value, as demonstrated by a value contained in secret_token.rb in an open-source product.
Cross-site scripting (XSS) vulnerability in activesupport/lib/active_support/core_ext/string/output_safety.rb in Ruby on Rails before 3.0.17, 3.1.x before 3.1.8, and 3.2.x before 3.2.8 might allow remote attackers to inject arbitrary web script or HTML via vectors involving a ' (quote) character.
Cross-site scripting (XSS) vulnerability in actionpack/lib/action_view/helpers/sanitize_helper.rb in the strip_tags helper in Ruby on Rails before 3.0.17, 3.1.x before 3.1.8, and 3.2.x before 3.2.8 allows remote attackers to inject arbitrary web script or HTML via malformed HTML markup.
Multiple SQL injection vulnerabilities in the quote_table_name method in the ActiveRecord adapters in activerecord/lib/active_record/connection_adapters/ in Ruby on Rails before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allow remote attackers to execute arbitrary SQL commands via a crafted column name.
Cross-site scripting (XSS) vulnerability in the strip_tags helper in actionpack/lib/action_controller/vendor/html-scanner/html/node.rb in Ruby on Rails before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allows remote attackers to inject arbitrary web script or HTML via a tag with an invalid name.
Cross-site scripting (XSS) vulnerability in activesupport/lib/active_support/core_ext/string/output_safety.rb in Ruby on Rails 2.x before 2.3.13, 3.0.x before 3.0.10, and 3.1.x before 3.1.0.rc5 allows remote attackers to inject arbitrary web script or HTML via a malformed Unicode string, related to a "UTF-8 escaping vulnerability."
The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not properly handle mutation of safe buffers, which makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method, as demonstrated by the sub method.
Multiple cross-site scripting (XSS) vulnerabilities in the mail_to helper in Ruby on Rails before 2.3.11, and 3.x before 3.0.4, when javascript encoding is used, allow remote attackers to inject arbitrary web script or HTML via a crafted (1) name or (2) email value.
Ruby on Rails 2.1.x, 2.2.x, and 2.3.x before 2.3.11, and 3.x before 3.0.4, does not properly validate HTTP requests that contain an X-Requested-With header, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via forged (1) AJAX or (2) API requests that leverage "combinations of browser plugins and HTTP redirects," a related issue to CVE-2011-0696.
Cross-site scripting (XSS) vulnerability in Ruby on Rails 2.x before 2.2.3, and 2.3.x before 2.3.4, allows remote attackers to inject arbitrary web script or HTML by placing malformed Unicode strings into a form helper.
