Rails vulnerabilities

SQL injection vulnerability in the 'order' method in Ruby on Rails 5.1.4 and earlier allows remote attackers to execute arbitrary SQL commands via the 'id desc' parameter. NOTE: The vendor disputes this issue because the documentation states that this method is not intended for use with untrusted input

Cross-site scripting (XSS) vulnerability in json/encoding.rb in Active Support in Ruby on Rails 3.x and 4.1.x before 4.1.11 and 4.2.x before 4.2.2 allows remote attackers to inject arbitrary web script or HTML via a crafted Hash that is mishandled during JSON encoding.

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.

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.

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.

Cross-site scripting (XSS) vulnerability in the strip_tags function in Ruby on Rails before 2.2.s, and 2.3.x before 2.3.5, allows remote attackers to inject arbitrary web script or HTML via vectors involving non-printing ASCII characters, related to HTML::Tokenizer and actionpack/lib/action_controller/vendor/html-scanner/html/node.rb.

The example code for the digest authentication functionality (http_authentication.rb) in Ruby on Rails before 2.3.3 defines an authenticate_or_request_with_http_digest block that returns nil instead of false when the user does not exist, which allows context-dependent attackers to bypass authentication for applications that are derived from this example by sending an invalid username without a password.

CRLF injection vulnerability in Ruby on Rails before 2.0.5 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted URL to the redirect_to function.

Multiple SQL injection vulnerabilities in Ruby on Rails before 2.1.1 allow remote attackers to execute arbitrary SQL commands via the (1) :limit and (2) :offset parameters, related to ActiveRecord, ActiveSupport, ActiveResource, ActionPack, and ActionMailer.

Session fixation vulnerability in Rails before 1.2.4, as used for Ruby on Rails, allows remote attackers to hijack web sessions via unspecified vectors related to "URL-based sessions."

Rails before 1.2.4, as used for Ruby on Rails, allows remote attackers and ActiveResource servers to determine the existence of arbitrary files and read arbitrary XML files via the Hash.from_xml (Hash#from_xml) method, which uses XmlSimple (XML::Simple) unsafely, as demonstrated by reading passwords from the Pidgin (Gaim) .purple/accounts.xml file.

Ruby on Rails before 1.1.5 allows remote attackers to execute Ruby code with "severe" or "serious" impact via a File Upload request with an HTTP header that modifies the LOAD_PATH variable, a different vulnerability than CVE-2006-4112.
