The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method.

Security readout for executives and security teams

CVE-2013-1854 is a denial-of-service flaw in older Ruby on Rails Active Record. A remote attacker could send crafted input that causes Rails to create many symbols during query handling, potentially exhausting memory and disrupting the application. Exposure is most likely in legacy Rails applications or vendor-packaged software still running affected Rails branches, especially internet-facing apps with user-driven search, filter, or query parameters. Treat as a targeted legacy-platform remediation item. It can affect availability, but the supplied evidence does not support active exploitation or critical emergency handling. Mitigation focus: Upgrade Rails to 2.3.18, 3.1.12, 3.2.13, or later supported versions.; Review OS vendor advisories if Rails is supplied through a Linux or Apple package.; Prioritize externally reachable Rails applications handling user-controlled query parameters..
