[EDIT]: I have added a "Wireshark" capture which I obtained by plugging the disc (node) into my laptop via ethernet, and then turning on the disc. (ZIP attached)
I've got a new mesh router + discs set ("EE" Smart router + 3 of their "Smart WiFi discs"). Each disc is a node, and in the user guide it says that, to configure each disc, merely plug it into the smart router via ethernet until the disc led is solid blue, then disconnect - okay, fine.
Question: what protocol or data/methods are being employed to auto setup the discs this way, and could this be exploited by someone with a device that emulates the conversation the two devices are having, to steal credentials? I'm by no means a networking expert, but know enough.
Thank you.
