The decode_credentials method in actionpack/lib/action_controller/metal/http_authentication.rb in Ruby on Rails 3.x 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.

Security readout for executives and security teams

CVE-2012-3424 is a denial-of-service flaw in Ruby on Rails Digest Authentication handling. A vulnerable application can be forced to consume resources when it uses Rails HTTP Digest helpers. Business impact is service disruption, not data theft, based on the provided sources. Exposure is most likely in legacy Ruby on Rails 3 applications that enabled HTTP Digest Authentication on public or semi-public routes. Applications not using those helpers are less likely exposed by this CVE. Treat as a targeted legacy-platform availability risk. Prioritize remediation where Rails 3 applications remain internet-facing and use Digest Authentication. Modern or non-Digest deployments are lower priority, but unsupported Rails versions should still be retired. Mitigation focus: Upgrade Rails to 3.0.16, 3.1.7, 3.2.7, or later supported versions.; Identify and prioritize internet-facing Rails routes using HTTP Digest Authentication helpers.; Review Ruby on Rails security advisory and distribution advisories for package-specific fixes..
