Executive brief
SQL Server is Microsoft's relational database platform used by organizations worldwide to store and manage critical business data. This vulnerability allows an authorized database user to inject malicious SQL commands and escalate their privileges, potentially gaining administrative access to the database and the sensitive information it contains.
Technical details
The vulnerability is an improper neutralization of special elements in SQL commands (SQL injection, CWE-89) in SQL Server. It allows an authenticated attacker with existing database access to craft specially-formed SQL statements that bypass input validation and execute arbitrary commands at elevated privilege levels. The attack requires network access and existing database credentials; unauthenticated remote access is not possible. Successful exploitation grants the attacker elevated privileges within SQL Server, potentially enabling data exfiltration, modification, or deletion. Microsoft has issued a security update; patch availability should be verified through the Microsoft Security Response Center.
