Any system connected to the internet running the Intelligent Platform Management Interface (IPMI) may be affected. IPMI is resident on many server platforms, and provides low-level access to a system that can override operating system controls.
Attackers can easily identify and access systems that run IPMI and are connected to the Internet. It is important to restrict IPMI access to specific management IP addresses within an organization and preferably separated into a separate LAN segment.
