description

Tenda AC19 firmware 16.03.10.07 is affected by a stack-based buffer overflow in its HTTP web management service. A remote attacker may be able to trigger the flaw through the firewall configuration handler; the evidence indicates no authentication or user interaction prerequisite.

mitigation

Restrict access to the router's web management interface to trusted administrative networks and disable remote administration where possible. No fixed firmware version is recorded; monitor Tenda for an updated AC19 firmware release and apply it promptly.
