CVE-2025-4632

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa

Improper limitation of a pathname to a restricted directory vulnerability in Samsung MagicINFO 9 Server version before 21.1052 allows attackers to write arbitrary file as system authority.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CWE-22 (path traversal) en aplicación expuesta (AV:N, PR:N, UI:N) permite escritura de archivos arbitrarios como sistema, combinando lectura de datos sensibles, manipulación de archivos y potencial ejecución remota.

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.
