Advisory ID: ZSL-2014-5206
Type: Local/Remote
Impact: Spoofing
Risk: (2/5)
Release Date: 18.11.2014

Summary

Snowfox is an open source Content Management System (CMS) that allows your website users to create and share content based on permission configurations.

Description

Input passed via the 'rd' GET parameter in 'selectlanguage.class.php' script is not properly verified before being used to redirect users. This can be exploited to redirect a user to an arbitrary website e.g. when a user clicks a specially crafted link to the affected script hosted on a trusted domain.
