CVE-2022-3353: Hitachienergy FOX615 TEGO1 Firmware

High severity, CVSS 7.5. EPSS: 1.1% chance of exploitation in the next 30 days.

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.
