Inspired by all the awesome apps for Samsung TV's and by Luigi Auriemma his PoC to crash one. I started looking a little bit more to my own Samsung. Well a little bit more wasn't necesary at all. I quickly found that there is no filtering of any input at all and close to every string sent to the television will crash it. Here's an easy PoC for everyone at home.
Fire up your browser, enter the ip-adres of the Samsung TV with the correct TCP port: 55000, hit <enter>.
Thats -seriously- enough to crash a Samsung TV. Have fun, don't forget to check out the wireless lan's at the pubs, bring your smartphone, but please don't spoil the games. ;) Any browser works.
