A url redirection to untrusted site ('open redirect') in Fortinet FortiWeb version 6.4.1 and 6.4.0, version 6.3.15 and below, version 6.2.6 and below allows attacker to use the device as a proxy and reach external or protected hosts via redirection handlers.
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
