Executive brief
Azure SQL Database, a cloud-hosted relational database service used by enterprises to store and manage critical business data, is vulnerable to SQL injection attacks. An authorized attacker with network access can inject malicious SQL commands to bypass authentication controls and escalate privileges, potentially gaining unauthorized access to sensitive data or performing unauthorized operations on the database.
Technical details
This SQL injection vulnerability exists in Azure SQL Database's handling of SQL commands, where user-supplied input is not properly sanitized before execution. An attacker with valid credentials and network access to the database can craft malicious SQL statements to elevate privileges beyond their assigned role or permissions. The vulnerability allows privilege escalation over the network without requiring additional user interaction. A patch is required from Microsoft to properly neutralize special characters and validate SQL command syntax.
