rails vulnerable to improper authentication (GHSA-rxq3-gm4p-5fj4)
Published: 2017-10-24T18:33:38Z
Aliases: CVE-2009-2422
Severity: HIGH · CWE: CWE-287

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.
