Critical GNU InetUtils Telnetd Flaw: Another Glorious Pile of Sysadmin Misery

Oh for fuck’s sake, just when you thought the rotting corpse of Telnet couldn’t get any worse, along comes this steaming pile of security disaster. The geniuses maintaining GNU InetUtils apparently left a goddamn hole big enough for a tank to roll through — a critical vulnerability in the telnetd service that lets some smug bastard bypass login and waltz in as root. Yep, instant admin access, no credentials, no lube, just pure exploitation bliss for every lowlife hacker out there.

Apparently, this little gift came courtesy of a bug in the way Telnetd handles environment variables. So some clever asshole figured out he could just shove some magic bytes up the daemon’s ass and, bingo, he’s got shell access faster than you can say “deprecated protocol.” The cherry on top? This affects the latest version of InetUtils. You know, the one you thought was safe because it was last updated sometime during the goddamn Bronze Age.

So what’s the fix? Update or kill Telnet entirely. Seriously, if you’re still running Telnet in 2026, you deserve the digital equivalent of tetanus. Use SSH like a sane person. The maintainers have rolled out a patch, but considering the whole protocol should’ve been buried decades ago, this feels a bit like putting duct tape on a burning oil tanker.

You can read the whole sorry saga here, if you enjoy watching humanity collectively fail at basic security hygiene:

Reminds me of the time some bright spark in accounting spun up an old SunOS box “for testing,” and two hours later we had Russian spambots mining goddamn crypto on it. I swear, technology’s greatest enemy isn’t hackers — it’s the idiots still using Telnet in the year of our lord twenty-fucking-twenty-six.
