"According to its self-reported version, the instance of Dotnetnuke running on the remote web server is prior to 10.3.3.
It is, therefore, affected by a vulnerability.

  - An authorization vulnerability in the Journal module could allow an authenticated user to add comments to
    private journal posts they are not authorized to view. Sites using the Journal module should upgrade to a
    patched release to ensure comment operations respect journal privacy settings. A vulnerability was
    identified in the Journal module's handling of comments on private journal posts. Under certain
    conditions, insufficient authorization checks could allow an authenticated user with minimal privileges to
    add comments to private journal entries that they are not permitted to view or interact with. While the
    vulnerability does not expose the contents of private journal posts, it allows unauthorized users to add
    comments to private content. In addition to compromising the integrity of private activity streams, this
    could be used for social engineering by creating the false impression that the commenter had legitimate
    access to or participation in a private discussion. (GHSA-86mr-4mmw-j9g2)

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