Estado: AplazadaAlta (7.5)—

Integer Overflow in fast_ping.c in SmartDNS Release46 allows remote attackers to cause a Denial of Service via misaligned memory access.

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 remota (AV:N/PR:N/UI:N) con desbordamiento de enteros causando DoS por acceso a memoria desalineada. El vector CVSS (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirma acceso remoto sin privilegios ni interacción.

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.
