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.

Description

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.
