Estado: AnalizadaCrítica (9.8)—

TOTOLINK A3002R v4.0.0-B20230531.1404 was discovered to contain a buffer overflow via the routername parameter in the formDnsv6 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.

Vector CVSS AV:N/AC:L/PR:N/UI:N indica explotación remota sin privilegios (T1190). Buffer overflow en parámetro accesible (routername) permite RCE con contexto de root del dispositivo, dando ejecución de comandos (T1059) y escalada (T1068).

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.
