CVE-2025-20994

Estado: AnalizadaAlta (7.1)—

Improper handling of insufficient permission in SyncClientProvider in Samsung Internet installed on non-Samsung Device prior to version 28.0.0.59 allows local attackers to access read and write arbitrary files.

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:L + PR:L + UI:N indica escalada de privilegios local (T1068). El acceso de lectura/escritura a ficheros arbitrarios genera T1005 (lectura) y T1565.001 (manipulación 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.
