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 controller suffers from an authenticated path traversal vulnerability. This can be exploited through the 'devName' POST parameter in the ethernetUpdate.php script to write partially controlled content, such as IP address values, into arbitrary file paths, potentially leading to configuration tampering and system compromise including denial of service scenario through ethernet configuration backup file overwrite.
