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: DDL). Supported versions that are affected are 8.0.35 and prior and 8.2.0 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. CVSS 3.1 Base Score 5.5 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H).

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.

How this class of weakness works · CWE-284

The application fails to correctly restrict what a user can do or reach, so functions or resources are available to people who should not have them. Attackers simply probe for the paths where the check is missing or wrong. The fix is to enforce access-control decisions consistently on every request, evaluated against the acting user rather than assumed from context.

Recommended fix High confidence

MySQL 8.0.36+ or MySQL 8.2.1+

  1. 1. Identify the current MySQL Server version using: SELECT VERSION();
  2. 2. For MySQL 8.0.x (versions 8.0.0 through 8.0.35): Upgrade to MySQL 8.0.36 or later
  3. 3. For MySQL 8.2.x (versions 8.1.0 through 8.2.0): Upgrade to MySQL 8.2.1 or later
  4. 4. Download the appropriate MySQL release from https://dev.mysql.com/downloads/mysql/
  5. 5. Back up all databases before performing the upgrade
  6. 6. Follow MySQL upgrade procedures documented at https://dev.mysql.com/doc/refman/8.0/en/upgrading.html
  7. 7. After upgrade, verify the server starts successfully and test application functionality
  8. 8. For Oncommand Insight: No vendor patch available as of the January 2024 advisory; consider vendor support options or alternative solutions
Caveat MySQL minor version upgrades are generally safe but always test in staging first; review MySQL 8.0.36 and 8.2.1 release notes for any behavioral changes
