Technical details
Buffer overflow vulnerabilities exist in the underlying operating system of EdgeConnect SD-WAN Gateways. The vulnerability is exploitable by an unauthenticated adjacent network attacker under certain preconditions outside the attacker's control. Successful exploitation allows arbitrary code execution with privileged user rights on the underlying OS, leading to complete system compromise. The attack requires network adjacency but not authentication. Patch availability should be confirmed with HPE/Silverpeak support.
