CVE-2025-27396

Status: AnalyzedHigh (8.7)—

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly limit the elevation of privileges required to perform certain valid functionality. This could allow an authenticated lowly-privileged remote attacker to escalate their privileges.

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).
