The ABB BMS/BAS controller is vulnerable to code execution and sudo misconfiguration flaws. An authenticated remote code execution vulnerability in the firmware update mechanism allows an attacker with valid credentials to escalate privileges and execute commands as root. The process involves uploading a crafted .bsx file through projectUpdateBSXFileProcess.php, which is then moved to htmlroot and executed by projectUpdateBSXExecute.php. This script leverages sudo to run the uploaded bsx file, enabling the attacker to bypass input validation checks and execute arbitrary code, leading to full system compromise and unauthorized root access.
