Summary
DNN (formerly DotNetNuke), an open-source web content management platform (CMS) in the Microsoft ecosystem, prior to version 10.1.0 allowed users to inject JavaScript code in the Biography field, even if that field is not rich-text. The injected code would run in the context of the website for any user viewing the profile, including administrators and/or superusers. This issue has been patched in version 10.1.0.
Risk Assessment
An attacker can inject malicious JavaScript that executes for administrators viewing the profile, potentially leading to takeover of high-privileged accounts and full control of the site.
Recommendation
Update DNN to version 10.1.0 or later, which contains the fix for this issue.
