Welp, this is bad.
QuoteI didn't have anybody touching the airplane; I didn't have an insider threat. I stood off using typical stuff that could get through security, and we were able to establish a presence on the systems of the aircraft.

Yeah, it is. Why this information is published though, is bewildering.
I suspect it was leaked to put pressure on fixing the vulnerability.
QuoteA Hack In The Box presentation by Hugo Teso in 2013 suggested that thanks to the lack of authentication features in the protocol Aircraft Communications Addressing and Report System (ACARS), an airliner could be controlled via an Android app. Flight management software companies, as well as the FAA, disputed Teso's claims.
All of that means that airline pilots have heard of those vulnerabilities before, too. Yet at a technical meeting in March 2017, several shocked airline pilot captains from American Airlines and Delta were briefed on the 2016 Boeing 757 hack. Hickey said, "All seven of them broke their jaw hitting the table when they said, 'You guys have known about this for years and haven't bothered to let us know because we depend on this stuff to be absolutely the bible.'"
All planes with this vulnerability should probably be grounded until the fix. I could see some script-kiddy accidentally killing himself and the rest of the passengers while poking around with a laptop running
Kali Linux (https://www.kali.org/).
