enjoyed this telnetd analysis. (if you can’t believe anyone has a legitimate operational reason to run telnet, you live in a cozy world indeed) https://labs.watchtowr.com/a-32-year-old-bug-walks-into-a-telnet-server-gnu-inetutils-telnetd-cve-2026-32746/

A 32-Year-Old Bug Walks Into A Telnet Server (GNU inetutils Telnetd CVE-2026-32746)

A long, long time ago, in a land free of binary exploit mitigations, when Unix still roamed the Earth, there lived a pre-authentication Telnetd vulnerability. In fact, this vulnerability was born so long ago (way back in 1994) that it may even be older than you. To put the timespan

@0xabad1dea do you have a specific example of such a legit need? I do not typically think of myself as “sheltered” but this one eludes me

I can think of one reason, terminal servers; though most serial terminals these days support ssh. Even the one I have support ssh; though I used telnet rather than ssh as it was out of habbit. Plus I was using it on my own local network only and never exported.
