A vulnerability exists in the IEC 61850 communication stack that affects multiple Hitachi Energy products. An attacker could exploit the vulnerability by using a specially crafted message sequence, to force the IEC 61850 MMS-server communication stack, to stop accepting new MMS-client connections. Already existing/established client-server connections are not affected.

WID-SEC-W-2024-2105Hitachi Energy Relion: Mehrere Schwachstellen ermöglichen Denial of ServiceDeutsch2024-09-10csaf · cert_bundDE
Ein Angreifer aus einem angrenzenden Netzwerk oder ein entfernter anonymer Angreifer kann mehrere Schwachstellen in Hitachi Energy Relion ausnutzen, um einen Denial of Service Angriff durchzuführen.
ICSA-23-089-01Hitachi Energy IEC 61850 MMS-Server (Update B)2023-02-14icsa · cisa_csaf_otUS
Hitachi Energy is aware of a reported vulnerability in the IEC 61850 communication stack, that is used in the Relion® 670, 650 and SAM600-IO products versions listed in this document. A version is available that remediates the identified vulnerability. An attacker who successfully exploited this vulnerability could force the IEC 61850 MMS-server communication stack to stop accepting new MMS-client connections. A manual reboot is required to reenable IEC 61850 MMS-server communication for accepting new MMS-client connections. During the reboot phase, the primary functionality of the device is not available.
