CVE-2025-27395

Estado: AnalizadaAlta (8.6)—

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly limit the scope of files accessible through and the privileges of the SFTP functionality. This could allow an authenticated highly-privileged remote attacker to 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:N + PR:H (red, privilegios altos) → T1210. SFTP sin límites de acceso permite lectura (T1005) y escritura (T1565) de archivos arbitrarios en dispositivo Siemens.

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.
