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.
