DescriptionBuffer overflow vulnerabilities exist in the API endpoint of HPE Networking EdgeConnect SD-WAN Gateways 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 on the underlying operating system leading to complete system compromise.
