A denial-of-service vulnerability exists in the U-SPEED N300 V1.0.0 wireless router. By sending a large number of concurrent HTTP requests to random or non-existent endpoints on the web management interface, an attacker can exhaust system resources in the embedded Boa HTTP server. This causes the router web interface to become unresponsive and may require manual reboot to restore normal operation.
