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
| CPE | Name | Operator | Version |
|---|---|---|---|
| rubyonrails:ruby_on_rails | rubyonrails ruby on rails | lt | 2.3.3 |
