Dan Regalado from Zingbox reported this vulnerability to NCCIC.
Vecna has released a recommended update to mitigate the vulnerabilities. Vecna recommends the following update process:
- By default, VGo has automatic updates enabled so all updates are performed automatically when Internet access is available. If the VGo is powered off or in use, a message will appear on the screen asking if it can be updated when the VGo is next used.
- If a VGo unit has automatic updates turned off, the update will not be downloaded (however, a notice about the update will be displayed on the VGo's screen). Vecna recommends that automatic updates be turned on. Select “settings” from the main menu then “advanced settings” then “automatic updates.”
