What to do
AI-suggested
1. Immediately restrict access to the router’s web management interface by implementing network-level controls such as firewall rules or VPN-only access. 2. Disable remote management features if not strictly necessary to reduce exposure. 3. Monitor network traffic for unusual HTTP requests targeting login.cgi or abnormal command execution patterns. 4. Replace or isolate vulnerable Wavlink AC3000 devices until a vendor patch is released. 5. Regularly check Wavlink’s official channels for firmware updates addressing this vulnerability and apply them promptly. 6. Employ network segmentation to limit the impact of potential device compromise. 7. Use intrusion detection/prevention systems (IDS/IPS) with signatures for command injection attempts targeting this router model. 8. Educate IT staff about this vulnerability to ensure rapid response and mitigation. 9. Consider deploying endpoint detection on critical systems to detect lateral movement originating from compromised routers.
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_week_value` POST parameter.
