CVE-2017-6957

Estado: ModificadaAlta (8.1)—

Desbordamiento de búfer basado en pila en el firmware en Broadcom Wi-Fi HardMAC SoC chips, cuando el firmware soporta CCKM Fast y Secure Roaming y la funcionalidad está habilitada en RAM, permite a atacantes remotos ejecutar código arbitrario a través de marco de respuesta de reasociación manipulado con un Cisco IE (156).

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).
