What is CVE-2014-7818?

A directory traversal vulnerability exists in the Action Pack component of Ruby on Rails, specifically within the middleware handling static assets. When the serve_static_assets feature is enabled, remote attackers can exploit this vulnerability to reveal the existence of files outside the application’s root directory by utilizing a crafted request containing a /..%2F sequence. This poses a serious threat as it can lead to unauthorized information disclosure, potentially allowing attackers to access sensitive files and configurations stored on the server.
