XSS via posted select tag options
Ruby on Rails is vulnerable to remote cross-site scripting because the application does not validate manually generated `select tag options` upon submission to `actionpack/lib/action_view/helpers/form_options_helper.rb`. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.

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.

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.
