Privilege escalation via stored procedure SQL injection
Published Aug 12, 2025 · Updated Feb 13, 2026
SQL injection in Microsoft SQL Server allows remote authenticated users to elevate privileges by invoking affected stored procedures. Certain system stored procedures fail to neutralize SQL metacharacters in attacker-controlled input, allowing injected commands to run as code with elevated database privileges. Exploitation requires an authenticated account with access to those procedures; Microsoft has not identified the procedure names or exact privilege gained.
