CVE-2025-27397

Status: AnalyzedMedium (5.1)—

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' .

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
