What to do
AI-suggested
- Immediately restrict access to the router’s management interface to trusted networks and users only, employing network segmentation and firewall rules.
- Enforce strong authentication mechanisms and regularly audit credentials to prevent unauthorized access.
- Monitor router logs and network traffic for unusual authenticated HTTP POST requests targeting the internet.cgi endpoint, especially those involving the 'gateway' parameter.
- Disable remote management interfaces if not strictly necessary to reduce attack surface.
- Engage with Wavlink support or vendor channels to obtain firmware updates or patches addressing CVE-2024-39763 as soon as they become available.
- Consider deploying network intrusion detection systems (NIDS) with signatures targeting command injection patterns in router management traffic.
- Implement strict input validation and filtering at network perimeters where possible to detect and block malicious payloads.
- Prepare incident response plans specific to router compromise scenarios, including device isolation and forensic analysis.
- For organizations with large deployments, conduct an inventory of affected devices and prioritize patching or replacement.
- Educate network administrators on the risks of command injection vulnerabilities and the importance of secure configuration management.
Description
Multiple OS command injection vulnerabilities exist in the internet.cgi set_add_routing() 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 command injection vulnerability exists in the `gateway` POST parameter.
