Security researchers found a remote exploitable critical vulnerability in a building management system used by businesses, hospitals, factories and other organizations. The vulnerability affects enteliBUS Manager (eBMGR), a control system that can be used to manage different I/O switches connected to things like sensors, alarms, motors, locks, valves and other industrial equipment. The vendor has released a firmware update, but hundreds of these systems are still exposed on the internet. McAfee estimated the total number of targets at around 1,600, but many more exist inside enterprise networks.”]
