TP-Link TL-WR740N Wireless Router Remote Denial Of Service Exploit

The TP-Link WR740N Wireless N Router network device is exposed to a remote denial of service vulnerability when processing a HTTP request. This issue occurs when the web server (httpd) fails to handle a HTTP GET request over a given default TCP port 80. Sending a sequence of three dots (…) to the router will crash its httpd service denying the legitimate users access to the admin control panel management interface. To bring back the http srv and the admin UI, a user must physically reboot the router.
