Does this matter?

Lower severity and a low EPSS score (0.35%). Track it; it rarely justifies an emergency change on its own.

Description

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.
