Description

It was discovered that Rails, the Ruby web application development framework, performed insufficient validation on input parameters, allowing unintended type conversions. An attacker may use this to bypass authentication systems, inject arbitrary SQL, inject and execute arbitrary code, or perform a DoS attack on the application.
