  #Description:
  #Vulnerability exists in web interface
  #This router has vulnerabilities where you can get information or edit
  configurations in an unauthenticated way.
  #The biggest risk is the possibility of changing the dns of the device.
  #
  #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).
  #
