Language:

Synopsis

An ASP.NET application running on the remote web server is affected by a vulnerability.

Description

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 a like to a private journal post they are not authorized to access. Sites using the Journal module should upgrade to a patched release to ensure journal privacy settings are consistently enforced. A vulnerability was identified in the Journal module where authorization checks were not consistently enforced when recording likes on private journal posts. Under certain conditions, an authenticated user with minimal privileges could add a like to a private journal entry despite not having permission to view it. While the vulnerability does not expose the contents of private journal posts or allow modification of their content, it may create visible interactions associated with private activity, potentially causing confusion or giving the appearance that unauthorized users were able to participate in private discussions, which could be leveraged to help with a social engineering attack. (GHSA-r4c4-vmqp-vxf2)

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

Solution

Upgrade to Dotnetnuke version 10.3.3 or later.
