## Technical details

An open redirect vulnerability exists in the Console component of Puppet Enterprise due to improper validation of the 'redirect' parameter in the login URL. Attackers can bypass existing character filters by using a double forward slash (//) followed by an external domain. This flaw is an incomplete fix for a previous vulnerability (CVE-2015-6501). Successful exploitation requires a user to click a malicious link, which then redirects them to an attacker-controlled site after or during the authentication process, facilitating phishing or credential theft. The issue is resolved in Puppet Enterprise version 2016.4.0.
