CVE-2016-0753

Active Model en Ruby on Rails 4.1.x en versiones anteriores a 4.1.14.1, 4.2.x en versiones anteriores a 4.2.5.1 y 5.x en versiones anteriores a 5.0.0.beta1.1 soporta el uso de los escritores a nivel de instancia para descriptores de acceso de clase, lo que permite a atacantes remotos eludir los pasos destinados a la validación a través de parámetros manipulados.

A flaw was found in the way the Active Model based models processed attributes. An attacker with the ability to pass arbitrary attributes to models could possibly use this flaw to bypass input validation.

The rh-ror41 collection provides Ruby on Rails version 4.1. Ruby on Rails is a model-view-controller framework for web application development. The following issue was corrected in rubygem-actionpack and rubygem-actionview: A directory traversal flaw was found in the way the Action View component searched for templates for rendering. If an application passed untrusted input to the 'render' method, a remote, unauthenticated attacker could use this to render unexpected files and, possibly, execute arbitrary code.
