CVE-2022-38452Public exploit

Root command execution via hidden telnet trigger

Published Mar 21, 2023 · Updated Feb 26, 2025

Command execution in NETGEAR Orbi RBR750 4.6.8.5 allows remote authenticated users to execute arbitrary commands over the local network. The UDP port 23 trigger handler decrypts a packet carrying the br-lan MAC address and administrator credentials, then enables a hidden telnet service that opens a root shell. Access requires the Wi-Fi password or Ethernet connectivity, administrator credentials, and the router serial number and MAC address.
