Descriptions

Symfony 2.0.x before 2.0.20 does not process URL encoded data consistently within the Routing and Security components, which allows remote attackers to bypass intended URI restrictions via a doubly encoded string.

Symfony v2.0.20 antes de v2.0.x no procesa los datos de URL codificadas consistentemente dentro de los componentes de seguridad y enrutado, lo que permite a atacantes remotos evitar las restricciones de acceso a URIs a través de una cadena doblemente codificada.
