Security readout for executives and security teams

This flaw affects Microsoft .NET Framework 4.6.2 applications that use SQL Server Always Encrypted with a developer-supplied key. If that key is guessable, a remote attacker may bypass the intended encryption protection and obtain sensitive data in cleartext. Exposure is likely limited to applications running Microsoft .NET Framework 4.6.2 that use the SQL Server Data Provider with Always Encrypted and developer-supplied keys. Organizations not using this combination are less likely to be affected based on the available sources. Treat this as a targeted data-confidentiality risk, not a broad internet-wide emergency. Prioritize systems that protect regulated or high-value data with SQL Server Always Encrypted on .NET Framework 4.6.2. Mitigation focus: Apply the relevant Microsoft guidance and updates from MS16-155 where applicable.; Inventory applications using .NET Framework 4.6.2 and SQL Server Always Encrypted.; Review developer-supplied encryption keys for guessability or weak generation practices..
