Description

Buffer overflow vulnerabilities exist in the underlying operating system of EdgeConnect SD-WAN Gateways that could allow an unauthenticated adjacent attacker to execute arbitrary code if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system leading to complete system compromise.
