Greetings from the VMware Security Response Center!
It has come to our attention that a previously resolved vulnerability identified by CVE-2018-6961 which affected VMware SD-WAN Edge (Velocloud) prior to v3.1.2 has been reported to be included as one of multiple injection methods for a newly discovered variant of the Mirai malware. Unit 42 has a good write up on what they have discovered here: https://unit42.paloaltonetworks.com/new-mirai-variant-adds-8-new-exploits-targets-additional-iot-devices.
VMware is actively conducting our own investigation into the matter.
