CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Ruby on Rails up to 3.x/4.x (Programming Language Software). It has been classified as critical. Affected is an unknown functionality of the file request.rb of the component Web Console. The manipulation of the argument X-Forwarded-For with an unknown input leads to a access control vulnerability (Blacklist). CWE is classifying the issue as CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.
