Title: ABB Cylon Aspect 3.08.02 (uploadDb.php) Remote Code Execution
Advisory ID: ZSL-2025-5904
Type: Local/Remote
Impact: System Access, DoS
Risk: (5/5)
Release Date: 09.01.2025

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 OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the contents of an uploaded .db file, which is passed to the copyFile.sh script. Although the filename is sanitized, the contents of the .db file are not, allowing attackers to inject malicious commands that are executed on the server.
