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.
List of affected CPEs:
CPE | Name | Operator | Version |
---|---|---|---|
hitachienergy:sys600_firmware | hitachienergy sys600 firmware | le | 10.3.1 |
