Summary: enteliTOUCH - Touchscreen Building Controller. Get instant
access to the heart of your BAS. The enteliTOUCH has a 7-inch,
high-resolution display that serves as an interface to your building.
Use it as your primary interface for smaller facilities or as an
on-the-spot access point for larger systems. The intuitive,
easy-to-navigate interface gives instant access to manage your BAS.

Desc: The application suffers from a cleartext transmission/storage
of sensitive information in a Cookie. This allows a remote
attacker to intercept the HTTP Cookie authentication credentials
through a man-in-the-middle attack.
