Headline
ABB Cylon Aspect 4.00.00 (factorySetSerialNum.php) Remote Code Execution
The ABB Cylon Aspect BMS/BAS controller suffers from an unauthenticated blind command injection vulnerability. Input passed to the serial and ManufactureDate POST parameters is not properly sanitized, allowing attackers to execute arbitrary shell commands on the system. While 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.
