cross-site scripting vulnerability because the application fails to
properly sanitize user-supplied input. The vulnerability exists due to
a flaw in the code used to generate the pop-up modal windows.

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