Thousands of unauthenticated, open printer ports exist reachable on the Internet. And Masscan exists. And a bored neo-Nazi exists. Of course Weev could have done more than send just a page advertising DailyStormer to each of these printers – he could have sent firmware updates. On one hand, these (mostly University) printers got an education in Information Security. On the other hand, sometimes sending swastikas to random people who don’t share your ideology of hate is not that funny even if it does let you use angry messages on Twitter as a way to find out when your attack worked.
There’s no CVE for this issue because CVE is dead.
