CVE-2013-0333: lib/active_support/json/backends/yaml.rb in Ruby on Rails 2.3.x before 2.3.16 and 3.0.x before 3.0.20 does...

lib/active_support/json/backends/yaml.rb in Ruby on Rails 2.3.x before 2.3.16 and 3.0.x before 3.0.20 does not properly convert JSON data to YAML data for processing by a YAML parser, which allows remote attackers to execute arbitrary code, conduct SQL injection attacks, or bypass authentication via crafted data that triggers unsafe decoding, a different vulnerability than CVE-2013-0156.

Security readout for executives and security teams

Old Ruby on Rails versions could mishandle JSON by passing unsafe data into YAML processing. A remote attacker could use crafted input to reach serious outcomes, including code execution, SQL injection, or authentication bypass. This is mainly a legacy-application risk, but any exposed Rails 2.3 or 3.0 service should be treated urgently. Likely exposure is legacy Ruby on Rails applications using 2.3.x before 2.3.16 or 3.0.x before 3.0.20, especially public web or API endpoints accepting JSON. Downstream packaged Rails deployments should follow their vendor advisories, including Debian, Red Hat, Apple, and Puppet references in the bundle. Treat confirmed exposure as urgent, especially for externally reachable legacy Rails applications. The stated impact includes remote code execution and authentication bypass. If no affected Rails versions remain, priority drops to documentation and dependency hygiene. Mitigation focus: Upgrade Rails 2.3.x deployments to 2.3.16 or later.; Upgrade Rails 3.0.x deployments to 3.0.20 or later.; Apply distribution or vendor security updates where Rails is packaged..
