A remote code execution vulnerability exists in the underlying operating system of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system, leading to complete compromise of the HPE Networking Fabric Composer host.
