What to do

AI-suggested

  1. Immediately verify if your Wavlink AC3000 devices run the vulnerable firmware version M33A8.V5030.210505 and prioritize their remediation.
  2. 3. Restrict access to the router’s management interface by implementing network segmentation and firewall rules to limit HTTP management access to trusted internal IP addresses only. 4. Enforce strong authentication mechanisms and change default credentials to reduce the risk of credential compromise. 5. Disable FTP services if not required or restrict FTP configuration changes to highly trusted administrators. 6. Monitor network traffic for unusual HTTP POST requests targeting nas.cgi or abnormal FTP configuration changes. 7. Implement intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect exploitation attempts. 8. Conduct regular security audits and penetration testing focusing on router management interfaces. 9. Educate IT staff about the risks of configuration injection vulnerabilities and the importance of timely patching. 10. Consider deploying network access control (NAC) solutions to enforce device compliance and reduce exposure.

Description

Multiple external config control vulnerabilities exist in the nas.cgi set_ftp_cfg() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to permission bypass. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A configuration injection vulnerability exists within the `ftp_name` POST parameter.
