CVE-2026-21005

Estado: AnalizadaAlta (7.1)—

Path traversal in Smart Switch prior to version 3.7.69.15 allows adjacent attackers to overwrite arbitrary files with Smart Switch privilege.

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+acceso local sugiere aplicación local interactiva. Path traversal (CWE-22) permite sobrescribir archivos con privilegios de Smart Switch, implicando manipulación y lectura de datos.

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.
