What to do
AI-suggested
Immediate mitigation steps include restricting access to the router’s web management interface to trusted internal networks and enforcing strong authentication policies to prevent unauthorized access. Network segmentation should be implemented to isolate management interfaces from general user traffic. Organizations should monitor network traffic for unusual HTTP requests targeting the internet.cgi endpoint and the set_add_routing() function. Since no official patches are currently available, consider replacing affected devices with updated models or alternative vendors that have addressed this vulnerability. Employing Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom rules to detect and block command injection patterns in HTTP POST requests can provide additional protection. Regularly audit router configurations and credentials to ensure no default or weak passwords are in use. Finally, maintain vigilance for vendor updates or security advisories that provide patches or further guidance.
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 `custom_interface` POST parameter.
