Estado: AnalizadaCrítica (9.8)—

Azure Front Door Elevation of Privilege Vulnerability

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.

AV:N sin PR/UI → T1190. CVSS I:H/C:H/A:H en servicio público (Azure Front Door) permite escalada de privilegios (T1068), lectura de datos confidenciales (T1005) y modificación de contenido (T1565).

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.
