Vulnerability CVE-2015-3224
Published: 2015-07-26   Modified: 2015-07-27

Description:
request.rb in 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.
