"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 Social Groups module could allow a group owner to modify another
    group's information. Sites using Social Groups should upgrade to a patched release to ensure ownership
    validation is consistently enforced during group management operations. A vulnerability was identified in
    the Social Groups module where ownership validation was not consistently enforced during group management
    operations. Under certain conditions, a user with permission to manage one social group could perform
    modifications to another group they do not own. Successful exploitation could allow unauthorized changes
    to editable group information, compromising the integrity of affected social groups. In addition, an
    attacker could use these unauthorized modifications for social engineering by publishing misleading or
    fraudulent content that appears to originate from the legitimate group owners or administrators.
