CVE-2022-27647

Root code execution via libreadycloud command injection

Published Mar 29, 2023 · Updated Feb 18, 2025

OS command injection in libreadycloud.so on NETGEAR R6700v3 1.0.4.120_10.0.91 allows remote attackers to execute code as root. The library passes an unvalidated name or email field into a system call, allowing shell command injection. Exploitation requires local-network access by WiFi password or Ethernet connection; the authentication check can be bypassed, and injected commands run with root privileges.
