Hackers Can Make Siemens Building Automation Controllers 'Unavailable for Days'
A vulnerability affecting building automation controllers from Siemens can be exploited to disrupt a device for an extended period of time, according to OT and IoT cybersecurity firm Nozomi Networks.
Nozomi researchers recently analyzed Siemens’ PXC4.E16, a programmable building automation system (BAS) of the Desigo family that is designed for HVAC and building service plants.
They discovered that the device, specifically its ABT Site Engineering and Commissioning Tool, is affected by a vulnerability that can be exploited for denial-of-service (DoS) attacks.
