CVE-2014-0130

Vulnerabilidad de salto de directorio en actionpack/lib/abstract_controller/base.rb en la implementación implicit-render en Ruby on Rails anterior a 3.2.18, 4.0.x anterior a 4.0.5 y 4.1.x anterior a 4.1.1, cuando ciertas configuraciones de coincidencia de patrones en rutas basadas en caracteres comodín (globbing) están habilitadas, permite a atacantes remotos leer archivos arbitrarios a través de una solicitud manipulada.

A directory traversal flaw was found in the way Ruby on Rails handled wildcard segments in routes with implicit rendering. A remote attacker could use this flaw to retrieve arbitrary local files accessible to a Ruby on Rails application using the aforementioned routes via a specially crafted request.

Red Hat CloudForms Management Engine delivers the insight, control, and automation needed to address the challenges of managing virtual environments. CloudForms Management Engine is built on Ruby on Rails, a model-view-controller framework for web application development. Action Pack implements the controller and the view components. The SSH utility script created a world-writable file in /tmp/ using a predictable name, and then executed it as root. A local attacker could use this flaw to execute arbitrary commands as the root user. A directory traversal flaw was found in the way Ruby on Rails handled wildcard segments in routes with implicit rendering. A remote attacker could use this flaw to retrieve arbitrary local files accessible to a Ruby on Rails application using the aforementioned routes via a specially crafted request.

Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails allows remote attackers to read arbitrary files via a crafted request.
