I have a laptop that is not capable of running any versions of Windows above XP reliably, but that I want to connect to use to browse web using the last version of Firefox available for Windows XP. I don't care about this laptop's security at all, as there is nothing of value, but I wonder if running such a device on a network poses a security threat to all other devices on this network if it gets compromised?
And what are the attack vectors and known exploits that could use a Windows XP machine as a leverage to break into more protected devices on this network?
