What is CVE-2022-3864?

A vulnerability exists in the update package signature validation within Hitachi Energy's Relion platform. This flaw allows an attacker who gains security privileges to exploit the system by attempting to upload a malicious update package. When successfully exploited, the vulnerability leads to a restart of the Intelligent Electronic Device (IED), resulting in a temporary disruption of service. Although the device returns to normal operation post-restart, the potential for misuse poses serious security risks to infrastructure relying on the IEDs. Organizations should mitigate this risk by ensuring strict access control and validating update packages before installation.
