MitigationSICK MEAC2012 with Microsoft Windows 10 Version 1903 & 1909sick_psirt
Should Microsoft's remediation not be possible, we recommend following the workaround suggested by Microsoft and operate the MEAC in a protected networking environment. Blocking TCP port 445 at the perimeter firewall of the network segment will help to protect systems that are behind that firewall from exploits of this vulnerability.

SCA-2020-0003MEAC affected by Windows SMBv3 vulnerability2020-08-07csaf · sick_psirtDE
Microsoft disclosed a critical vulnerability in the way Microsoft Server Message Block 3.1.1 (SMBv3) handles compressed connections. That may allow unauthenticated attackers to execute arbitrary code on a vulnerable device. Since the MEAC central emission monitoring computer (EPC) acts as a SMB server to provide MEAC workstations with access to the filesystem in distributed MEAC-systems, the devices are affected by this vulnerability. Exploitation of this vulnerability could lead to remote code execution under login with administrator privileges.
