CVE-2025-7448

Estado: AplazadaAlta (8.6)—

Wi-SUN unexpected 4- Way Handshake packet receptions may lead to predictable keys and potentially leading to Man in the middle (MitM) attack

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.

AV:A (red adyacente) + CWE-290 (deficiencia criptográfica) sugiere T1210. El ataque MitM genera acceso no autorizado (T1078) e interceptación de comunicaciones (T1557).

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.
