Senserva AI Opinion for CVE-2018-6961

VMware SD-WAN Edge appliances from VeloCloud accept command injection through their local web UI, ending in remote code execution on the device that carries all of a branch office's traffic. SD-WAN edges are deployed in bulk at remote sites and managed centrally, so a missed firmware cycle leaves whole regions exposed, which the 86 percent EPSS score and KEV listing suggest attackers understand well. Severity is High at CVSS 8.1.

Do this: Verify every SD-WAN Edge is on fixed firmware and restrict its local web UI to management networks only.
