8.0.0.14, 8.5.0.x prior to 8.5.5.13 or 9.0.x prior to 9.0.0.5. It is, therefore, affected by an HTTP response splitting
vulnerability. An unauthenticated, remote attacker can exploit this, by using a specially crafted URL to cause the
server to return a split response once the URL is clicked. The attacker could then perform further attacks.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
