CVE-2026-21079

Estado: AnalizadaAlta (7)—

Missing encryption of sensitive data in Smart Switch prior to version 3.7.72.6 allows adjacent attackers to intercept transmitted data.

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 + UI:P sugieren interacción del usuario con datos no cifrados. El atacante en la red adyacente (AV:A) puede interceptar datos sensibles (CWE-311) durante la transmisión, combinando ejecución en cliente (T1203) con lectura de información (T1005) y ataque MITM (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.
