A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests, aka 'Windows SMBv3 Client/Server Remote Code Execution Vulnerability'.

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.

Schneider Electric is aware of multiple Microsoft Windows vulnerabilities in its Schneider Conext™ Advisor 2 & Conext™ Control V2 products. The Conext™ Advisor 2 is a web portal with an efficient, task-oriented interface for managing and optimizing the performance of solar power plants and includes a complete suite of tools for professional users. The Conext™ Control V2 is a Solar Power Plant monitoring solution. Failure to apply the remediations provided below may risk remote code execution, which could result in undesired behavior within the operating system. An attacker who successfully exploits this vulnerability could execute arbitrary code on the target system and then install programs; view, change, or delete data; or create new accounts with full user rights.
