Package Instance

actionpack Improper Authentication vulnerability
The `decode_credentials` method in `actionpack/lib/action_controller/metal/http_authentication.rb` in Ruby on Rails before 3.0.16, 3.1.x before 3.1.7, and 3.2.x before 3.2.7 converts Digest Authentication strings to symbols, which allows remote attackers to cause a denial of service by leveraging access to an application that uses a `with_http_digest` helper method, as demonstrated by the `authenticate_or_request_with_http_digest` method.

activerecord vulnerable to SQL Injection
The Active Record component in Ruby on Rails efore 2.3.15, 3.0.x before 3.0.14, 3.1.x before 3.1.6, and 3.2.x before 3.2.6 does not properly implement the passing of request data to a where method in an ActiveRecord class, which allows remote attackers to conduct certain SQL injection attacks via nested query parameters that leverage improper handling of nested hashes, a related issue to CVE-2012-2661.

Ruby on Rails Potential XSS Vulnerability in select_tag prompt
When a value for the `prompt` field is supplied to the `select_tag` helper, the value is not escaped. If untrusted data is not escaped, and is supplied as the prompt value, there is a potential for XSS attacks.

Multiple vulnerabilities in parameter parsing in Action Pack
There are multiple weaknesses in the parameter parsing code for Ruby on Rails which allows attackers to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on a Rails application.

actionpack Cross-site Scripting vulnerability
Cross-site scripting (XSS) vulnerability in `actionpack/lib/action_view/helpers/sanitize_helper.rb` in the `strip_tags` helper in Ruby on Rails before 2.3.16, 3.0.x 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.

activesupport Cross-site Scripting vulnerability
Cross-site scripting (XSS) vulnerability in `activesupport/lib/active_support/core_ext/string/output_safety.rb` in Ruby on Rails before 2.3.16, 3.0.x before , 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.

Unsafe Query Generation Risk in Ruby on Rails
Due to the way Active Record interprets parameters in combination with the way that JSON parameters are parsed, it is possible for an attacker to issue unexpected database queries with "IS NULL" or empty where clauses. This issue does *not* let an attacker insert arbitrary values into an SQL query, however they can cause the query to check for NULL or eliminate a WHERE clause when most users wouldn't expect it.

Active Record contains SQL Injection
SQL injection vulnerability in the Active Record component in Ruby on Rails before 2.3.15, 3.0.x before 3.0.18, 3.1.x before 3.1.9, and 3.2.x before 3.2.10 allows remote attackers to execute arbitrary SQL commands via a crafted request that leverages incorrect behavior of dynamic finders in applications that can use unexpected data types in certain find_by_ method calls.
