Senserva AI Opinion for CVE-2024-43519

CVE-2024-43519 is a remote code execution flaw in the Microsoft WDAC OLE DB provider for SQL Server, carrying a Critical rating with CVSS 9.0. It affects Windows 10 Version 1809 (32-bit and x64) and Windows Server 2019, so any of these hosts running applications that use the OLE DB provider to connect to SQL Server are exposed.
