Explain the vulnerability: CVE-2022-3353
Description:


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.
