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 unauthenticated blind command injection vulnerability. Input passed to the serial and ManufactureDate POST parameters is not properly sanitized, allowing attackers to execute arbitrary shell commands on the system. While factory test scripts included in the upgrade bundle are typically deleted, a short window for exploitation exists when the device is in the manufacturing phase.
