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