CVE-2024-21410

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa💥 PoC

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

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.

🎯 Técnicas ATT&CK

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

Vector CVSS AV:N/AC:L/PR:N sin UI indica explotación remota directa de aplicación expuesta (T1190). CWE-287 (autenticación débil) facilita obtención de credenciales/acceso (T1078). La criticidad sugiere ejecución de comandos (T1059) y manipulación de datos (T1565.001) como impactos secundarios en Ex

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.
