CVE-2016-7270
HighSummary
The Data Provider for SQL Server in Microsoft .NET Framework 4.6.2 mishandles a developer-supplied key, allowing remote attackers to bypass the Always Encrypted protection mechanism and obtain sensitive cleartext information.
Risk Assessment
Organizations may be exposed to the disclosure of confidential data, potentially leading to serious privacy and security breaches.
Recommendation
It is recommended to update to the latest version of .NET Framework and implement additional security measures to protect encryption keys.
