CVE-2026-24714Public exploitNetwork attack vector

Unauthenticated Telnet activation via magic packet

Published Jan 30, 2026 · Updated Jan 30, 2026

Hidden functionality in NETGEAR PR2000 firmware allows remote attackers to activate Telnet via a magic packet on the LAN interface. The undocumented TelnetEnable functionality processes a specially formed LAN-side packet and starts the Telnet service without an authorization check. An attacker must reach the device's LAN interface; activation changes its service state, while public records do not establish credential-free Telnet login.
