Security researchers warn about widespread vulnerabilities in protocol gateways. Small devices connect industrial machinery and sensors to TCP/IP networks that are used to automate and control them. New research presented at the Black Hat USA virtual security conference highlights a new threat via protocol translation attacks. The identified vulnerabilities can enable various attack scenarios, from issuing stealth commands that could sabotage the operational process to gaining unauthorized access, decrypting configuration databases, exposing sensitive information and crashing critical equipment. The devices investigated were Nexcom NIO50, Schneider Link 150, Digi One IA, Red Lion DA10D and Moxa MGate 5105-MBEIP.”]
