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 10.1.1, el proveedor predeterminado del editor HTML permite la carga de archivos no autenticados y las imágenes pueden sobrescribir archivos existentes. Un usuario no autenticado puede cargar y reemplazar archivos existentes, lo que permite desfigurar un sitio web y, combinado con otro problema, la inyección de cargas útiles XSS. Esta vulnerabilidad se corrigió en la versión 10.1.1.
