I've successfully tested the PoC in the #SafeBreach Labs GitHub repository. It seems like a good place to start to write a checker (if there isn't a good one).

#CVE_2026_24061 #telnetd #vulnerability

Any good, legitimate checker around for CVE-2026-24061 ?

Exploitation is trivial, checking for the vulnerability, not so much.

#CVE_2026_24061 #telnetd #vulnerability

Exploitation is completely trivial...

#CVE_2026_24061 #telnetd #vulnerability

vagrant init debian/bookworm64
vagrant up
vagrant ssh 

sudo bash
apt update
apt install inetutils-telnetd=2:2.4-2+deb12u1 inetutils-telnet=2:2.4-2+deb12u1

1. Edit /etc/inetd.conf to enable telnetd
2. systemctl restart inetutils-inetd
3. Check telnet is running (ss -tupln | grep :23)

Congratulations, you got yourself a system vulnerable to CVE-2026-24061 !
