Estado: AnalizadaCrítica (9.8)—

TOTOLINK A3002R v4.0.0-B20230531.1404 was discovered to contain a buffer overflow via the dnsaddr parameter in the formDhcpv6s interface.

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.

Buffer overflow remoto en parámetro de entrada sin autenticación (AV:N/PR:N/UI:N). CWE-120 típicamente permite RCE. CVSS crítico con confidencialidad, integridad y disponibilidad totales sugiere ejecución de código y posible escalada.

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.
