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

The ABB Cylon Aspect BMS/BAS controller through webServerDeviceLabelUpdate.php script allows authenticated attackers to inject arbitrary content via the 'deviceLabel' POST parameter, leading to writing content to a fixed file location (/usr/local/aam/etc/deviceLabel) and potentially causing denial of service.

Mitigation:

Ensure proper input validation on the 'deviceLabel' parameter to prevent arbitrary content injection. Regularly update to the latest firmware version provided by ABB Ltd.

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.
