CVE-2026-102137

Estado: En análisisMedia (4.1)—

An authenticated administrator could bypass the content validation applied to an administrative file upload and store a file containing dangerous content on the appliance. This did not by itself result in code execution, which would require a separate vulnerability to run the stored file.

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.

Usuario autenticado con privilegios eleva bypass de validación en carga de archivos administrativos. Requiere acceso previo y privilegios altos (PR:H), consistente con T1210. El almacenamiento de contenido peligroso sin ejecución directa apunta a T1505.003 (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.
