Crafted delegations or IP fragments can poison cached delegations in Recursor.

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.

CVE en servicio de red sin autenticación (AV:N PR:N) permite enviar consultas DNS manipuladas (delegaciones o fragmentos) para envenenar caché, alterando respuestas DNS (CWE-294, I:H) y causando denegación parcial de servicio (A:L).

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.
