CVE-2025-64094 Details
Description
DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to 10.1.1, sanitization of the content of uploaded SVG files was not covering all possible XSS scenarios. This vulnerability exists because of an incomplete fix for CVE-2025-48378. This vulnerability is fixed in 10.1.1.
A stored cross-site scripting vulnerability has been identified in DNN (formerly DotNetNuke) versions prior to 10.1.1. This issue arises from inadequate sanitization of uploaded SVG files, which failed to address all potential cross-site scripting scenarios. The vulnerability is a result of an incomplete fix for CVE-2025-48378, allowing malicious SVG files to be uploaded and execute arbitrary JavaScript in the context of the user's browser. This could lead to various attacks, including data exfiltration, session hijacking, and defacement of the web application.
Users can upgrade to DNN version 10.1.1 or later to address this vulnerability.
