The remote host is running a version of FortiOS that is 7.0.x through 7.0.5 or 6.4.x through 6.4.9. It is, therefore, affected by a cross-site scripting (XSS) vulnerability due to improper neutralization of input during web page generation. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, 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.
