CVE-2026-20996

Estado: AnalizadaAlta (7.1)—

Use of a broken or risky cryptographic algorithm in Smart Switch prior to version 3.7.69.15 allows remote attackers to configure a downgraded scheme for authentication.

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.

UI:R + AV:N indica explotación en cliente (T1203). CWE-327 (criptografía débil) permite degradar autenticación, afectando T1556 (manipulación de mecanismos de autenticación) y T1078 (acceso con credenciales válidas).

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.
