Title: ABB Cylon Aspect 3.08.02 (licenseUpload.php) Stored Cross-Site Scripting
Advisory ID: ZSL-2025-5905
Type: Local/Remote
Impact: Cross-Site Scripting, DoS
Risk: (5/5)
Release Date: 10.01.2025

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 authenticated stored cross-site scripting (XSS) vulnerability. This can be exploited by uploading a malicious .txt file containing an XSS payload, which is stored on the server and served back to users. Although the filename is sanitized via the filename POST parameter, the file contents are not inspected or sanitized, allowing attackers to inject arbitrary client-side scripts that execute in the context of any user accessing the infected file or related web page (license.php). To bypass file upload checks, the request must include the Variant string, enabling the upload process for potential exploitation.
