Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions that are affected are 8.0.29 and prior. Easily exploitable vulnerability allows low 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. CVSS 3.1 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

Plain-English summary

This MySQL Server flaw can let a low-privileged network user make the database hang or crash repeatedly. The stated impact is availability only, not data theft or data modification. Business urgency depends on whether affected MySQL 8.0.29 or earlier systems support critical services or are reachable by untrusted users.

Executive priority

Treat as a moderate availability risk. Prioritize remediation for production databases, internet-adjacent deployments, shared environments, and services where MySQL downtime would interrupt revenue, operations, or customer-facing systems.

Technical view

CVE-2022-21569 affects Oracle MySQL Server 8.0.29 and prior in the Server: Optimizer component. It is network-exploitable with low privileges and no user interaction. Successful attack can cause a hang or frequently repeatable complete denial of service. CVSS is 6.5, with high availability impact and no confidentiality or integrity impact.

Likely exposure

Exposure is most likely where MySQL Server 8.0.29 or prior is running and reachable over network protocols by low-privileged authenticated users. NetApp customers should also review the linked NetApp advisory for product-specific applicability.

Exploitation context

The supplied sources do not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates easier exploitation: network access, low attack complexity, low privileges, and no user interaction. Evidence is insufficient to describe exploit maturity beyond the vendor CVE details.

Researcher notes

The source bundle names the Optimizer component but does not provide CWE, root-cause detail, proof-of-concept status, or fixed version specifics. Avoid assuming confidentiality or integrity impact. Validation should focus on version exposure, network reachability, privilege paths, and vendor update status.

Mitigation direction

  • Review Oracle July 2022 CPU guidance for MySQL Server.
  • Apply vendor-supported MySQL updates applicable to affected deployments.
  • Restrict network access to MySQL from untrusted hosts.
  • Limit low-privileged database accounts to required users only.
  • Review the NetApp advisory if using NetApp-managed affected components.

Validation and detection

  • Inventory MySQL Server versions and flag 8.0.29 or prior.
  • Confirm whether MySQL is reachable from untrusted networks.
  • Review database accounts with low privileges and network access.
  • Check maintenance records for Oracle CPU or later vendor updates.
  • Monitor MySQL logs for unexplained hangs or repeat crashes.
