"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.

  - A permission evaluation flaw could allow users with page-level content permissions to access module
    management features despite explicit module-level restrictions. Sites relying on module-level permission
    overrides should upgrade to a patched release to ensure access restrictions are consistently enforced. A
    vulnerability was identified in the platform's permission evaluation logic where, under certain
    conditions, explicit module-level access restrictions were not consistently enforced when broader page-
    level permissions were present. This could allow users granted page-level content management permissions
    to access module administration features that an administrator had explicitly restricted at the module
    level. As a result, module-specific permission settings may not behave as expected, potentially allowing
    unauthorized administrative actions within affected modules. (GHSA-hqgc-qj63-mx24)

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