CVE-2009-2422 (GCVE-0-2009-2422)

Vulnerability from cvelistv5 – Published: 2009-07-10 15:00 – Updated: 2024-08-07 05:52
VLAI
Summary
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.
