description

Tenda AC19 devices running 16.03.10.07 are affected in the web-management firewall configuration function. A remote attacker may cause a stack buffer overflow if they can reach the device's management service.

mitigation

Restrict the router management interface to trusted administrative networks and block access from the WAN or other untrusted segments. Monitor for a vendor firmware update and apply it when one is published.
