Technical details

A buffer overflow vulnerability exists in the underlying operating system of HPE EdgeConnect SD-WAN Gateways. The flaw is remotely exploitable without authentication, allowing an attacker to send specially crafted network packets that overflow a buffer and overwrite adjacent memory. Successful exploitation enables arbitrary code execution with the privileges of the vulnerable service, leading to complete system compromise. No authentication is required; the attacker must have network access to the appliance.
