What to do

AI-suggested

  1. Immediately verify if your Wavlink AC3000 devices are running the vulnerable firmware version M33A8.V5030.210505.
  2. Monitor Wavlink’s official channels for firmware updates or patches addressing CVE-2024-39798 and apply them promptly once available.
  3. Restrict access to the router’s management interface to trusted IP addresses and networks only, ideally via VPN or secure management VLANs.
  4. Enforce strong authentication mechanisms and rotate credentials regularly to reduce the risk of credential compromise.
  5. Disable the OpenVPN server functionality on the device if it is not required, to eliminate the attack surface.
  6. Implement network segmentation to limit the impact of a compromised router on the broader network.
  7. Employ network monitoring and intrusion detection systems to detect anomalous configuration changes or command execution attempts on the router.
  8. Conduct regular security audits and penetration tests focusing on network infrastructure devices.
  9. Educate network administrators on the risks of configuration injection vulnerabilities and the importance of secure device management practices.

Description

Multiple external config control vulnerabilities exists in the openvpn.cgi openvpn_server_setup() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary command execution. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.A configuration injection vulnerability exists in the `sel_open_protocol` POST parameter.
