Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper neutralization of special elements used in an sql command ('sql injection') in SQL Server allows an authorized attacker to elevate privileges over a network.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

SQL injection vulnerability in Microsoft SQL Server allows an authenticated attacker to inject malicious SQL commands, potentially elevating their privileges beyond their assigned database roles. The vulnerability is exploitable over the network by an authorized user.

MitigationApply Microsoft security updates for SQL Server promptly. Additionally, review and enforce least-privilege database accounts, implement parameterized queries to prevent injection, and audit existing stored procedures and application code for unsafe SQL construction.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify SQL Server version
    Run SELECT @@VERSION or SELECT SERVERPROPERTY('ProductVersion'), SERVERPROPERTY('ProductLevel')
    Affected if The returned version falls within any of these ranges: 2016 (13.0.6300.2 to 13.0.6475.1 OR 13.0.7000.253 to 13.0.7070.1), 2017 (14.0.1000.169 to 14.0.2095.1 OR 14.0.3006.16 to 14.0.3515.1), 2019 (15.0.2000.5 to 15.0.2155.2 OR 15.0.4003.23 to 15.0.4455.2), 2022 (16.0.1000.6 to 16.0.1160.1 OR 16.0.400
  2. Confirm SQL Server is accessible over the network
    Check SQL Server Configuration Manager or registry key for TCP/IP enabled network protocols, or test network connectivity to SQL Server port (default 1433)
    Affected if Network protocols are enabled and the instance accepts remote connections, allowing an authenticated network attacker to reach the database
  3. Verify authenticated user context exists
    Query SELECT CURRENT_USER, USER_NAME(), IS_SRVROLEMEMBER('sysadmin') to identify the current execution context
    Affected if Any non-sysadmin authenticated user has access to the SQL Server instance, as the vulnerability allows privilege elevation from any authenticated role

Your environment is affected if SQL Server is running any version within the affected ranges AND accepts authenticated connections, since the flaw allows any authenticated user to elevate privileges via SQL injection.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Upgrade available Upgrade to 13.0.6475.1 / 13.0.7070.1 / 14.0.2095.1 or later
Fixed in 13.0.6475.113.0.7070.114.0.2095.1
Interim mitigation

Apply Microsoft security updates for SQL Server promptly. Additionally, review and enforce least-privilege database accounts, implement parameterized queries to prevent injection, and audit existing stored procedures and application code for unsafe SQL construction.

Recommended fix High confidence

SQL Server 2016: upgrade to 13.0.6475.1 (SP2 CU13) or 13.0.7070.1 (SP3 CU7); SQL Server 2017: upgrade to 14.0.2095.1 (CU29) or 14.0.3515.1 (CU31); SQL Server 2019: upgrade to 15.0.2155.2 (CU23) or 15.0.4455.2 (CU28); SQL Server 2022: upgrade to 16.0.1160.1 (CU12) or 16.0.4222.2 (CU21)

  1. 1. Identify the currently installed SQL Server version by running 'SELECT @@VERSION;' in SQL Server Management Studio.
  2. 2. Determine which version branch your current installation falls into based on the affected version ranges provided.
  3. 3. Download the appropriate Cumulative Update (CU) or Service Pack that contains the fixed version for your SQL Server edition from Microsoft's official download center.
  4. 4. Before applying the update, perform a complete backup of all databases, including system databases.
  5. 5. Schedule a maintenance window as the update will require a brief service restart.
  6. 6. Apply the cumulative update following Microsoft's standard installation procedure: run the setup executable with appropriate parameters or use SQL Server Installation Center.
  7. 7. After installation, verify the SQL Server service restarted successfully and confirm the new version by running 'SELECT @@VERSION;'
Caveat Standard cumulative update with minimal risk; test in non-production environment first; requires brief service downtime
