actionpack Improper Input Validation vulnerability
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.
