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
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Packaging). Supported versions that are affected are 5.7.33 and prior and 8.0.23 and prior. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where MySQL Server executes to compromise MySQL Server. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Server accessible data as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N).

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

Vulnerability in MySQL Server's packaging component allows unauthenticated local attackers to potentially gain unauthorized access to critical data after successful human-interaction-based exploitation. The attack requires local logon access to the infrastructure where MySQL executes and human interaction from a person other than the attacker, leading to high confidentiality impact and low integrity impact.

MitigationApply Oracle's patches for MySQL versions 5.7.34+ and 8.0.24+ to address this packaging vulnerability. As this is a local attack vector, ensure strict access controls on systems running MySQL and verify installation package integrity.

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 Oracle MySQL Server version
    Run 'mysql --version' or check the MySQL service version via 'mysqld --version' or check the package manager for installed MySQL packages
    Affected if The installed version is greater than or equal to 8.0.0 and less than or equal to 8.0.23
  2. Identify NetApp product installations
    Check for installed NetApp components: look for 'Active Iq Unified Manager', 'Oncommand Insight', 'Oncommand Workflow Automation', or 'Snapcenter' in installed programs or running services
    Affected if Any NetApp product from the affected list (Active Iq Unified Manager, Oncommand Insight, Oncommand Workflow Automation, or Snapcenter) is installed, regardless of version
  3. Verify local access exposure
    Review local user accounts and remote access policies on the system running MySQL or NetApp products
    Affected if The system allows local user logon access by users other than administrators, as the vulnerability requires local logon capability

A system is affected if it runs Oracle MySQL 8.0.0 through 8.0.23, or any version of the listed NetApp products, AND permits local user logon access.
