  • MitigationU-Boot U-boot: <2017.11 installed on Johnson Controls Airwall AW-75 vers:all/*cisa_csaf_ot

    Johnson Controls recommend users to consider the following defensive measure: (1) Deploy Airwall in a physically secure location so an attacker can't plug in USB devices. (2) Restrict physical access to USB A ports (not the micro-USB console port which is not affected) by sealing them with epoxy or a similar material. (3) For Airwall 75 gateways running U-Boot version 2017.03 and before (version number is displayed on the console port as the Airwall gateway boots), install hotfix hf-3303 to update U-Boot.
