[NEU] [hoch] Hitachi Energy RTU500: Mehrere Schwachstellen

High-severity flaws in Hitachi Energy RTU500 — widely used in European grid operations — allow authentication bypass and DoS, directly threatening critical energy infrastructure.

Summary written by editorial AI · Source link below

Filed by CERT-Bund (BSI)1 min readRead at source ↗

Ein Angreifer kann mehrere Schwachstellen in Hitachi Energy RTU500 ausnutzen um Denial-of-Service-Zustände durch Anwendungsabstürze zu verursachen, Cookies oder Authentifizierungsinformationen an unbeabsichtigte Gegenstellen offenzulegen oder vorgesehene Authentifizierungskonfigurationen zu umgehen.

Editorial Analysis

Why it matters

RTU500 units underpin SCADA systems across European energy grids; authentication-bypass flaws could give attackers a foothold in operational technology networks covered by NIS2.

What to do

Verify network isolation of RTU500 devices, apply firmware updates from Hitachi Energy, and assess NIS2 notification obligations.

Board brief

Critical vulnerabilities in a widely deployed energy-grid component could enable attackers to bypass authentication — a direct risk to operational continuity and NIS2 compliance.
