Descriptions

The to_s method in actionpack/lib/action_dispatch/middleware/remote_ip.rb in Ruby on Rails 3.0.5 does not validate the X-Forwarded-For header in requests from IP addresses on a Class C network, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header.

El método to_s en actionpack/lib/action_dispatch/middleware/remote_ip.rb en Ruby on Rails v3.0.5 no valida la cabecera X-Forwarded-For de las peticiones de direcciones IP en una red de Clase C, lo que podría permitir a atacantes remotos la ejecución de documentos de texto en los archivos de registro o evitar análisis de direcciones intencionadas a través de una cabecera modificada.
