CWE-287

Description

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.

Affected configurations

• rubyonrails ruby on rails (< 2.3.3) • apple mac os x (>= 10.6.0 < 10.6.3) • apple mac os x 10.5.8 • apple mac os x server (>= 10.6.0 < 10.6.3) • apple mac os x server 10.5.8
