"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 server-side request forgery (SSRF) vulnerability in the Journal module could allow an authenticated user
    to cause the server to initiate requests to arbitrary network resources. Sites using the Journal module
    should upgrade to a patched release to ensure server-side requests are appropriately restricted. A
    vulnerability was identified in the Journal module's link preview functionality. Under certain conditions,
    insufficient validation of user-supplied URLs could allow an authenticated user to cause the server to
    make requests to arbitrary destinations on the network. Depending on the deployment environment,
    successful exploitation could allow an attacker to access or interact with network resources that are not
    directly reachable from the Internet, potentially exposing sensitive information or facilitating further
    attacks against internal services. (GHSA-hmwm-c2hx-wmxh)

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