Title: ABB Cylon Aspect 4.00.00 (factorySaved.php) Unauthenticated XSS
Advisory ID: ZSL-2025-5893
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (4/5)
Release Date: 03.01.2025

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 reflected cross-site scripting vulnerability in the 'title' GET parameter. Input is not properly sanitized before being returned to the user, allowing the execution of arbitrary HTML/JS code in a user's browser session in the context of the affected site. While the 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.
