CVE-2024-43642

Estado: AnalizadaAlta (7.5)—

Windows SMB Denial of Service 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.

Vulnerabilidad de red sin autenticación (AV:N, PR:N, UI:N) en SMB de Windows; impacto de disponibilidad (A:H) sugiere DoS de protocolo; CWE-416 (use-after-free) puede causar caída de servicio.

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.
