Dotnetnuke < 10.3.3 Server-Side request forgery in journal module (GHSA-hmwm-c2hx-wmxh)

high Nessus Plugin ID 339491

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.

- 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.

Solution

Upgrade to Dotnetnuke version 10.3.3 or later.
