"The version of Apache Struts running on the remote Windows host is 2.3.20 prior to 2.3.29 or 2.5.x < 2.5.13. It is,
therefore, affected by a denial of service vulnerability in URLValidator due to improper handling of form fields. An
unauthenticated, remote attacker can exploit this, via a crafted URL, to overload the server when performing validation
on the URL.

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