What to do
AI-suggested
1. Immediately identify all Wavlink AC3000 devices running firmware version M33A8.V5030.210505 within your network environment. 2. Restrict access to router management interfaces by implementing network segmentation and firewall rules to block HTTP access from untrusted networks, especially the internet. 3. Disable remote management features if not required or restrict them to trusted IP addresses only. 4. Monitor network traffic and device logs for unusual HTTP POST requests targeting login.cgi or other suspicious activity indicative of exploitation attempts. 5. If possible, replace affected devices with models from vendors with a strong security track record or updated firmware. 6. Regularly check Wavlink’s official channels for firmware updates or security advisories addressing this vulnerability and apply patches promptly once available. 7. Employ network intrusion detection/prevention systems (IDS/IPS) with signatures to detect exploitation attempts targeting this vulnerability. 8. Educate IT staff about the risks of exposed management interfaces and the importance of secure configuration. 9. Consider deploying network-level web application firewalls (WAF) to filter malicious HTTP requests targeting vulnerable endpoints. 10. Maintain an incident response plan to quickly isolate and remediate compromised devices.
Description
Multiple OS command injection vulnerabilities exist in the login.cgi set_sys_init() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger these vulnerabilities.A command injection vulnerability exists within the `restart_min_value` POST parameter.
