What to do
AI-suggested
- Immediately inventory all Wavlink AC3000 devices and verify firmware versions to identify affected units.
- Restrict administrative access to the router's web interface by limiting access to trusted IP addresses and enforcing strong authentication mechanisms, including multi-factor authentication if supported.
- Monitor network traffic and device logs for unusual authenticated HTTP POST requests targeting internet.cgi or abnormal routing table changes.
- Disable remote management interfaces if not required to reduce attack surface.
- Apply firmware updates from Wavlink as soon as they become available to patch the vulnerability.
- If patches are not yet available, consider temporary network segmentation or device replacement for critical environments.
- Educate users and administrators about the risk of credential compromise and enforce strong password policies.
- Employ network intrusion detection systems capable of detecting command injection patterns or anomalous router behavior.
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 `dest` POST parameter.
