What to do
AI-suggested
- Immediately restrict access to the router's web management interface by limiting it to trusted IP addresses or disabling remote management if not needed.
- Enforce strong authentication mechanisms for router access, including complex passwords and, if supported, multi-factor authentication.
- Monitor router logs and network traffic for unusual activity that could indicate exploitation attempts.
- Educate users and administrators to avoid visiting the router's web interface from untrusted devices or networks.
- Regularly check for firmware updates from Tenda and apply patches promptly once available.
- If possible, replace vulnerable Tenda AC18 routers with models that have confirmed security updates or better security track records.
- Implement network segmentation to isolate router management interfaces from general user networks.
- Use web application firewalls or network intrusion detection systems to detect and block suspicious payloads targeting the router interface.
