Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In DotNetNuke.Core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

DNN (aka DotNetNuke) before 9.2.0 suffers from a Server-Side Request Forgery (SSRF) vulnerability in the DnnImageHandler class. Attackers may be able to access information about internal network resources.
