# Exploit title: ABB Cylon Aspect 4.00.00 (factorySaved.php) Unauthenticated XSS
# Vendor: ABB Ltd.
# Product web page: https://www.global.abb
# Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=4.00.00

Summary: ASPECT is an award-winning scalable building energy management
and control solution designed to allow users seamless access to their
building data through standard building protocols including smart devices.

Desc: The ABB Cylon Aspect BMS/BAS controller suffers from an unauthenticated
reflected cross-site scripting vulnerability in the 'title' GET parameter.
Input is not properly sanitized before being returned to the user, allowing
the execution of arbitrary HTML/JS code in a user's browser session in the
context of the affected site. While the factory test scripts included in the
upgrade bundle are typically deleted, a short window for exploitation exists
when the device is in the manufacturing phase.

Tested on: GNU/Linux 3.15.10 (armv7l)
           GNU/Linux 3.10.0 (x86_64)
