CVE-2023-49473Public exploitNetwork attack vector

Unauthenticated root command execution via Telnet

Published Apr 30, 2024 · Updated Aug 2, 2024

Improper access control in iFreecomm JF6000 firmware 1.2.0 allows remote attackers to execute commands through the Telnet service. The remote-management service accepts Telnet connections without authentication, and its system CLI launches shell commands with root privileges. Network access to TCP port 23 is the only documented gate, exposing complete appliance control without credentials or user interaction.
