CVE-2022-46080Public exploitNetwork attack vector

Unauthenticated command execution via HTTPD-enabled Telnet

Published Jul 6, 2023 · Updated Nov 20, 2024

Authentication bypass in Nexxt Solutions Nebula1200-AC 15.03.06.60 allows remote attackers to execute commands through HTTPD. The HTTPD service accepts an unauthenticated request that enables the router's Telnet service without requiring a valid management session. Network access to HTTPD is sufficient, and successful exploitation exposes a Telnet-accessible command interface on the router.
