Estado: AnalizadaAlta (7.8)—

Improper authentication in Azure Arc allows an authorized attacker to elevate privileges locally.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.30%
Percentil entre todas las CVEs puntuadas: 21
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation85 %
Impacto principalT1078 Valid Accountsstealth · persistence · privilege escalation · initial access80 %
Impacto secundarioT1098 Account Manipulationpersistence · privilege escalation70 %

Vector CVSS AV:L/PR:L indica acceso local con privilegios; CWE-287 (autenticación impropia) permite escalada local. Acceso local autorizado se traduce en T1068. Impacto principal T1078 (acceso con identidades elevadas tras escalada).

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.
