The days of hacking home routers are not over! Because every household, that wants internet access at their house, needs some kind of router, these could be a very interesting target, as there are millions of devices in use with an direct connection to the internet. One might think, that manufacturer should take extra care to make them as secure as possible, but apparently there is still room for improvement. A lot of room.
This talk will show the accidental discovery of the most dangerous vulnerability type a device, especially a home router, can have: the unauthenticated remote code execution over the internet. It will not only focus on the technical part but also a practical example of how manufacturers should not respond to responsible disclosure.
Be curious about non existing input validation resulting in various outcomes, a lot of "Wait... what?" moments and the difficulties of responsible disclosure.
