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. Check MySQL Server version
    Run `mysql --version` from the command line, or connect to MySQL and execute `SELECT VERSION();`
    Affected if The version is between 8.0.0 and 8.0.21 inclusive
  2. Identify NetApp Active Iq Unified Manager
    Check if NetApp Active Iq Unified Manager is installed by looking for its installation directory or running `Get-ItemProperty` on typical install paths on Windows, or `ls` on typical Linux paths such as /opt/netapp or /usr/local/netapp
    Affected if The product is present on the system (all versions are affected)
  3. Identify NetApp Oncommand Insight
    Check if NetApp Oncommand Insight is installed by looking for its installation directory or service
    Affected if The product is present on the system (all versions are affected)
  4. Identify NetApp Oncommand Workflow Automation
    Check if NetApp Oncommand Workflow Automation is installed by looking for its installation directory or service
    Affected if The product is present on the system (all versions are affected)
  5. Identify NetApp Snapcenter
    Check if NetApp Snapcenter is installed by looking for its installation directory or service
    Affected if The product is present on the system (all versions are affected)

You are affected if you are running Oracle MySQL Server versions 8.0.0 through 8.0.21, or if any of the NetApp products (Active Iq Unified Manager, Oncommand Insight, Oncommand Workflow Automation, or Snapcenter) are installed on your system.
