CVE-2025-59821

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.1.0, DNN’s URL/path handling and template rendering can allow specially crafted input to be reflected into a user profile that is returned to the browser. In these cases, the application does not sufficiently neutralize or encode characters that are meaningful in HTML, so an attacker can cause a victim’s browser to interpret attacker-controlled content as part of the page’s HTML. This issue has been patched in version 10.1.0.

Summary		(es) DNN (anteriormente DotNetNuke) es una plataforma de gestión de contenido web (CMS) de código abierto en el ecosistema de Microsoft. Antes de la versión 10.1.0, el manejo de URL/rutas y la renderización de plantillas de DNN pueden permitir que una entrada especialmente diseñada se refleje en un perfil de usuario que se devuelve al navegador. En estos casos, la aplicación no neutraliza o codifica suficientemente los caracteres que son significativos en HTML, por lo que un atacante puede hacer que el navegador de una víctima interprete contenido controlado por el atacante como parte del HTML de la página. Este problema ha sido parcheado en la versión 10.1.0.
