It looks like 2 types of devices are being flagged in my home under the "Verified vulnerable services" section. Should this be added to your list of vulnerable devices?

• Linksys Velop Routers
• Bose SoundTouch 10 Speakers

Background

UPNP is enabled on the router to allow chromecast etc. to work. When I had read the Callstranger main website page, there were indications that only the UPNP endpoints exposed to the internet are vulnerable.

Questions

• Does that imply that the router is ok since it is not an endpoint?
• Additionally, the Bose SoundTouch 10 speaker sits behind the router, so does that mean it is okay as well?

Bottomline:
I can't seem to determine whether or not I am exposed, and I seem to need UPNP enabled in order for Chromecast to work etc. Help here is greatly appreciated!

Testing Results Info

Below are the 2x devices that were flagged under the "Verified vulnerable services" section.

for home users, it is not problem until ports exposed to internet you can use online services to check open ports like https://www.ipfingerprints.com/portscan.php
