CVE-2026-47632

Estado: ModificadaAlta (8.8)—

Improper certificate validation in Azure Connected Machine Agent allows an unauthorized attacker to elevate privileges over an adjacent network.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.50%
Percentil entre todas las CVEs puntuadas: 40
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.

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement85 %
Impacto principalT1557.002 ARP Cache Poisoningcredential access · collection80 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation75 %

AV:A (red adyacente) sin privilegios previos indica T1210. CWE-295 (validación incorrecta de certificados) + elevación de privilegios sustenta MITM (T1557.002) como impacto primario; escalada local secundaria (T1068).

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.
