CVE-2026-20999

Estado: AnalizadaAlta (7.1)—

Authentication bypass by replay in Smart Switch prior to version 3.7.69.15 allows remote attackers to trigger privileged functions.

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 (interacción del usuario) en vector CVSS indica explotación en cliente (T1203). CWE-294 (autenticación por replay) permite bypass, dando acceso a funciones privilegiadas (T1078.001 account access; T1098.002 account modification). Contexto: Samsung Smart Switch, aplicación cliente.

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.
