CVE-2022-21534: Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Stored Procedure).

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Stored Procedure). Supported versions that are affected are 8.0.29 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. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

Plain-English summary

CVE-2022-21534 is a denial-of-service flaw in Oracle MySQL Server stored procedure handling. An attacker already holding high MySQL privileges and network access could make the database hang or crash repeatedly, disrupting applications that depend on it. It does not indicate data theft or data modification in the provided sources.

Executive priority

Treat this as a reliability and service-continuity issue, not a data-breach indicator. Prioritize patching production MySQL systems that support critical applications, especially where many privileged users or broad network access exist.

Technical view

Affected product is Oracle MySQL Server 8.0.29 and prior. The CVSS vector is AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H, meaning remote network reachability, low attack complexity, high privileges required, no user interaction, and availability-only impact. No CWE, root-cause detail, or exploit procedure is provided in the bundle.

Likely exposure

Exposure is most relevant where MySQL Server 8.0.29 or earlier is reachable over the network by highly privileged database users. Internet exposure increases operational risk, but the privilege requirement limits broad unauthenticated exploitation.

Exploitation context

The provided sources and KEV flag do not show active exploitation. The vulnerability is described as easily exploitable only after the attacker has high privileges and network access via multiple protocols.

Researcher notes

Evidence is enough to assess affected versions and CVSS impact, but incomplete for root cause, CWE, exploit maturity, and exact fixed builds beyond vendor advisory guidance. Avoid assuming unauthenticated or data-compromise behavior.

Mitigation direction

  • Upgrade affected MySQL Server deployments per Oracle July 2022 CPU guidance.
  • Use applicable downstream vendor packages for Fedora or NetApp-managed environments.
  • Restrict MySQL network access to trusted application and administration hosts.
  • Review and reduce high-privilege MySQL accounts where operationally possible.
  • Monitor Oracle, NetApp, and Fedora advisories for environment-specific remediation notes.

Validation and detection

  • Inventory MySQL Server versions and identify systems at 8.0.29 or earlier.
  • Confirm whether Oracle, Fedora, or NetApp-supplied builds are in use.
  • Verify MySQL is not exposed beyond required trusted networks.
  • Review privileged database accounts with network access to affected servers.
  • Check database availability logs for unexplained hangs or repeated crashes.
