CVE-2025-64388

Estado: AplazadaCrítica (9.2)—

Denial of service of the web server through specific requests to this protocol

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.

Vector CVSS AV:N/AC:L sin autenticación (PR:N) indica explotación remota de aplicación expuesta. CWE-400 (Uncontrolled Resource Consumption) y descripción explícita de DoS del servidor web confirman T1499 como impacto.

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.
