CVE-2015-10083

Authentication bypass in basic_auth

Published Feb 21, 2023 · Updated Aug 6, 2024

Improper authentication in Harry's Dynosaur Rails allows remote attackers to access protected functions without valid credentials. The basic_auth function in app/controllers/application_controller.rb performs an undisclosed incorrect operation on supplied authentication data; the referenced upstream patch is no longer publicly retrievable. No prior credentials or user interaction are required, but the public record does not identify the accepted input or bound the accessible application functions.
