BACnet® Smart Building Controllers. ABB's BACnet portfolio features a series of BACnet® IP and BACnet MS/TP field controllers for ASPECT® and INTEGRA™ building management solutions. ABB BACnet controllers are designed for intelligent control of HVAC equipment such as central plant, boilers, chillers, cooling towers, heat pump systems, air handling units (constant volume, variable air volume, and multi-zone), rooftop units, electrical systems such as lighting control, variable frequency drives and metering.
The FLXeon Controller Series uses BACnet/IP standards to deliver unprecedented connectivity and open integration for your building automation systems. It's scalable, and modular, allowing you to control a diverse range of HVAC functions.
The ABB Cylon FLXeon BACnet controller is vulnerable to a path traversal flaw in its capture.js endpoint due to unsanitized user input being directly concatenated into a filesystem path. An attacker can exploit this by supplying crafted file names to access arbitrary files outside the intended var/ directory. Additionally, the use of Fs.unlinkSync() after serving the file introduces a destructive impact, allowing attackers to delete system or application files.
