# Rails Ruby on Rails: Ruby on Rails Directory Traversal Vulnerability

Ruby on Rails' implicit-render code in actionpack does not properly restrict paths, so a crafted request can make the app serve arbitrary files from the server. An attacker gets read access to files on the server, such as configuration and secrets, without logging in.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Rails Ruby on Rails affected ? fixed ?

## How to check

Check the Rails version in Gemfile.lock (grep -E "^    (actionpack|rails) " Gemfile.lock) and compare it with the fixed versions listed in the advisory.

## Fix

Upgrade actionpack/Rails to a release that includes the fix for CVE-2014-0130; the exact fixed version is unknown from the sources.
Upgrade to a supported Rails release and redeploy.

## From the sources

Directory traversal vulnerability in actionpack/lib/abstract_controller/base.rb in the implicit-render implementation in Ruby on Rails before 3.2.18, 4.0.x before 4.0.5, and 4.1.x before 4.1.1, when certain route globbing configurations are enabled, allows remote attackers to read arbitrary files via a crafted request.
