CVE-2022-41080

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa

Microsoft Exchange Server 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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vector AV:N/PR:N/UI:N con impacto C:H/I:H/A:H en Exchange Server expuesto indica explotación remota sin autenticación (T1190). Logra ejecución de código, escalada de privilegios y acceso a cuentas de usuario en el servidor.

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.
