CVE-2025-27397

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly limit user controlled paths to which logs are written and from where they are read. This could allow an authenticated highly-privileged remote attacker to read and write arbitrary files in the filesystem, if and only if the malicious path ends with 'log' .

Summary		(es) Se ha identificado una vulnerabilidad en SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (todas las versiones < V4.0). Los dispositivos afectados no limitan adecuadamente las rutas controladas por el usuario en las que se escriben los registros y desde dónde se leen. Esto podría permitir que un atacante remoto autenticado y con privilegios elevados lea y escriba archivos arbitrarios en el sistema de archivos, siempre y cuando la ruta maliciosa termine con 'log'.
