Summary #

Invicti detected RoR (Ruby on Rails) development mode is enabled, so the target web server is disclosing some system information data in the HTTP response.

Development mode enables extra debugging behaviors that assist developers, as well as attackers.

Impact #
An attacker can obtain information such as:
  • Middleware
  • Application root
This information might help an attacker gain more information and potentially to focus on the development of further attacks to the target system.
Remediation #
Change your config/application.rb file to disable development mode:
