A vulnerability exists in the Relion update package signature validation. A tampered update package could cause the IED to restart. After restart the device is back to normal operation. An attacker could exploit the vulnerability by first gaining access to the system with security privileges and attempt to update the IED with a malicious update package. Successful exploitation of this vulnerability will cause the IED to restart, causing a temporary Denial of Service.

A vulnerability exists in the input validation of the GOOSE messages where out of range values received and processed by the IED caused a reboot of the device. In order for an attacker to exploit the vulnerability, goose receiving blocks need to be configured.

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.
