Summary: We introduce SDT-CS3B1 LTE router which is a SKT 3G and 4G  
LTE wireless communication based LTE router product.  
  
Desc: The router suffers from authenticated arbitrary system command  
execution. The application interface allows users to perform certain  
actions via HTTP requests without performing any validity checks to  
verify the requests. This can be exploited to perform certain actions  
with administrative privileges if a logged-in user visits a malicious  
web site.
