Authenticated code execution via internal function processing
Published Jul 15, 2019 · Updated Aug 27, 2026
Remote code execution in Microsoft SQL Server 2014, 2016, and 2017 allows remote authenticated users to run code as the Database Engine service. The Database Engine incorrectly processes internal functions supplied through an authenticated database session; Microsoft has not disclosed the specific function or validation failure. A valid low-privilege SQL Server login is required, and successful exploitation runs code with the Database Engine service account's operating-system privileges.
