CVE-2024-40085

Estado: AplazadaCrítica (9.6)—

A Buffer Overflow vulnerability in the local_app_set_router_wan function of Vilo 5 Mesh WiFi System <= 5.16.1.33 allows remote, unauthenticated attackers to execute arbitrary code via pppoe_username and pppoe_password fields being larger than 128 bytes in length.

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 en función local accesible remotamente sin autenticación (AV:A, PR:N). Acceso a red adyacente en dispositivo WiFi mesh. La ejecución de código arbitrario via campos pppoe desbordados permite comandos y potencial escalada en sistema embebido.

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.
