ABB Cylon FLXeon 9.3.4 (timeConfig.js) Authenticated Root Remote Code Execution
    
    
    Vendor: ABB Ltd.
    Product web page: https://www.global.abb                   
    Affected version: FLXeon Series (FBXi Series, FBTi Series, FBVi Series)
                      CBX Series (FLX Series)
                      CBT Series
                      CBV Series
                      Firmware: <=9.3.4
    
    Summary: BACnetยฎ Smart Building Controllers. ABB's BACnet portfolio features a
    series of BACnetยฎ IP and BACnet MS/TP field controllers for ASPECTยฎ and INTEGRAโ„ข
    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.
    
    Desc: The ABB Cylon FLXeon BACnet controller is vulnerable to authenticated remote root
    code execution via the /api/timeConfig endpoint. An attacker with valid credentials
    can inject arbitrary system commands by manipulating parameters such as tz, timeServerYN,
    and multiple timeDate fields. The vulnerability exists due to improper input validation
    in timeConfig.js, where user-supplied data is executed via ChildProcess.exec() without
    adequate sanitization.
