Overview

rack-contrib includes a variety of add-on components for Rack, a Ruby web server interface.

Affected versions of the package are vulnerable to Cross-site Request Forgery (CSRF) attacks due to not properly restricting the SWF file format. An attacker can use JSONP callbacks to cause a trusted domain to return a specially crafted malicious SWF file, which can make requests to the trusted domain with the victims credentials. Note: Related to CVE-2014-4671.
