DEBIAN-CVE-2009-2422 PUBLISHED CVSS 9.800000190734863 CRITICAL

Record from OSV · Published July 10, 2009

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.
