Remote code execution via malicious server response
Published Feb 14, 2023 · Updated Aug 19, 2026
Improper input validation in the Windows WDAC OLE DB provider allows remote attackers to execute code after user interaction. The provider improperly validates a network packet returned during a connection to a malicious SQL Server; Microsoft has not disclosed the affected function or packet field. Exploitation requires a user to initiate the connection, after which attacker-controlled code runs in that user's security context.
