Ruby on Rails Improper Authentication Vulnerability - CVE-2009-2422

Critical
Reference: CVE-2009-2422
NVD Link: https://nvd.nist.gov/vuln/detail/CVE-2009-2422
Title: Ruby on Rails Improper Authentication Vulnerability
Overview:

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.
