#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).
