info:
  name: Ruby on Rails Web Console - Remote Code Execution
  author: pdteam
  severity: medium
  description: Ruby on Rails Web Console before 2.1.3, as used with Ruby on Rails 3.x and 4.x, does not properly restrict the use of X-Forwarded-For headers in determining a client's IP address, which allows remote attackers to bypass the whitelisted_ips protection mechanism via a crafted request to request.rb.
  impact: |
    Remote code execution can lead to unauthorized access, data breaches, and complete compromise of the affected system.
  remediation: |
    Upgrade to a patched version of Ruby on Rails or disable the Web Console feature.
