CVE-2025-32035

Estado: AnalizadaAlta (7.5)—

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to 9.13.2, when uploading files (e.g. when uploading assets), the file extension is checked to see if it's an allowed file type but the actual contents of the file aren't checked. This means that it's possible to e.g. upload an executable file renamed to be a .jpg. This file could then be executed by another security vulnerability. This vulnerability is fixed in 9.13.2.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Carga de archivos sin validación de contenido en CMS expuesto; permite subir ejecutables disfrazados como imágenes para posterior ejecución remota o web shell.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
