Risk Factors

Cisco HyperFlex HX hypervisors are not often exposed to the internet, but an unauthenticated attacker with network access to a HyperFlex device can leverage attack tools such as Metasploit modules to exploit this vulnerability. An attacker can gain complete control of a hypervisor within a data center and pivot to attack other systems in an organization.
