active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion.

Security readout for executives and security teams

CVE-2013-0156 is a Ruby on Rails parameter-parsing flaw that can let a remote attacker abuse XML/YAML type handling to run arbitrary code or exhaust server resources. Any legacy Rails application still on the affected 2.3, 3.0, 3.1, or 3.2 branches should be treated as urgent technical debt. Exposure is most likely in internet-facing or API-facing legacy Rails applications that accept XML parameters and run affected Rails versions. Packaged products embedding Rails may also be exposed, as shown by vendor advisories from Red Hat, Debian, Apple, Fujitsu, and Puppet. Treat this as high-priority remediation wherever legacy Rails is still in production. The business risk is not theoretical: the flaw can lead to remote code execution or denial of service, and affected versions are long out of support. Mitigation focus: Upgrade Rails to the fixed branch version or a later supported release.; Apply vendor security updates for packaged or embedded Rails distributions.; Check Rails and product vendor guidance for documented temporary workarounds..
