ABB Cylon Aspect 3.08.03 (webServerDeviceLabelUpdate.php) File Write DoS


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.03

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 authenticated
arbitrary content injection vulnerability in the webServerDeviceLabelUpdate.php
script due to a lack of input validation. Authenticated attackers can exploit
the 'deviceLabel' POST parameter to write arbitrary content to a fixed file
location at /usr/local/aam/etc/deviceLabel, potentially causing a denial of
service.

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