I am trying to find vulnerable & small CPS(cyber physical system) devices. I need these because I want to do model checking, threat modelling and other stuffs on them. I've tried to search on https://cve.mitre.org/ , but all I am finding is very big devices like MRI machine etc. And they cost a lot too.
Is there any way I can find smaller devices like heart rate monitor, solar panels etc. which has vulnerabilities and found recently?
If anyone can just show me the way, I'll be grateful.
