"The version of DNN Platform (formerly DotNetNuke) running on the
remote host is 3.0.0 or later but prior to 9.1.0. It is, therefore,
affected by a cross-site scripting (XSS) vulnerability due to improper
validation of user-supplied input when handling SWF files. An
unauthenticated, remote attacker can exploit this, via a specially
crafted request, to execute arbitrary script code in a user's browser
session.

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