2) Disable remote management features on the affected range extenders to prevent exploitation from external networks. 3) Monitor network traffic for unusual activity or command injection attempts targeting the /goform/setWan endpoint. 4) Replace or upgrade affected devices with models from vendors that provide timely security updates and have a strong security posture. 5) If replacement is not immediately feasible, consider deploying network intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect exploitation attempts. 6) Educate IT staff and users about the risks of using outdated firmware and the importance of applying updates promptly once available. 7) Regularly audit device firmware versions and configurations to ensure compliance with security best practices.
