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.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Ruby on Rails 3.0.x before 3.0.4 does not ensure that arguments to the limit function specify integer values, which makes it easier for remote attackers to conduct SQL injection attacks via a non-numeric argument.

activerecord vulnerable to SQL Injection
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.

Strong Parameter bypass with create_with
The `create_with` functionality in Active Record was implemented incorrectly and completely bypasses the strong parameter protection.

Improper Access Control
The Rails gem 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.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
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.

Nested attributes rejection proc bypass
When using the nested attributes feature in Active Record you can prevent the destruction of associated records by passing the `allow_destroy: false` option to the `accepts_nested_attributes_for` method. The `allow_destroy` flag prevents the `:reject_if` proc from being called because it assumes that the record will be destroyed anyway. However, this is not true if `:allow_destroy` is false so this leads to changes that would have been rejected being applied to the record. Attackers could set attributes to invalid values or clear all the attributes.

Improper Input Validation
Ruby on Rails 2.3.9 and 3.0.0 does not properly handle nested attributes, which allows remote attackers to modify arbitrary records by changing the names of parameters for form inputs.
