"The version of DNN Platform (formerly DotNetNuke) running on the remote host is 6.0.0 or later but prior or equal to
9.3.2. It is, therefore, affected by multiple vulnerabilities including the following:

  - An unauthorized file access vulnerability exists due to insufficient verification of dynamic file types. An
    authenticated, remote attacker can exploit this, to add or edit files on the remote host without permission.

  - An information disclosure vulnerability exists. An authenticated, remote attacker can exploit this, to disclose user
    account information.

  - A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input before returning
    it to users. 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 these issues but has instead
relied only on the application's self-reported version number.");
