CVE-2022-21522: 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. Difficult to exploit 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 4.4 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

Plain-English summary

CVE-2022-21522 is a denial-of-service flaw in Oracle MySQL Server stored procedure handling. A highly privileged network attacker could cause MySQL Server to hang or repeatedly crash. It does not indicate data theft or modification, but it can disrupt applications that depend on the database.

Executive priority

Treat this as a planned but timely database resilience fix. Prioritize systems supporting critical applications, externally reachable databases, and environments with broad privileged database access. The main business risk is outage, not confirmed data compromise.

Technical view

Oracle reports affected MySQL Server versions as 8.0.29 and prior. The CVSS vector is AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H, meaning network reachable, high complexity, high privileges required, no user interaction, and availability-only impact.

Likely exposure

Exposure is most relevant where MySQL Server 8.0.29 or earlier is reachable over the network and high-privilege database accounts exist. Public internet exposure increases operational risk, but the sources describe exploitation as difficult and requiring high privileges.

Exploitation context

The provided sources do not show active exploitation, and the CVE is not marked as CISA KEV in the bundle. Oracle describes the issue as difficult to exploit and requiring a high-privileged attacker with network access via multiple protocols.

Researcher notes

The source bundle provides no CWE, proof-of-concept, or exploit telemetry. Analysis should stay limited to Oracle's availability impact, high privilege requirement, high attack complexity, affected versions, and vendor advisory remediation paths.

Mitigation direction

  • Apply Oracle's July 2022 Critical Patch Update or later supported MySQL security updates.
  • For Fedora deployments, apply the referenced Fedora MySQL package advisories.
  • For NetApp-managed environments, follow NetApp advisory guidance for affected products.
  • Restrict MySQL network access to trusted hosts and administrative networks.
  • Review and minimize high-privilege MySQL accounts.

Validation and detection

  • Inventory MySQL Server versions and flag 8.0.29 or earlier.
  • Confirm Oracle CPU or later vendor patches are installed.
  • Check Fedora package versions where Fedora advisories apply.
  • Review MySQL exposure from untrusted networks.
  • Audit high-privilege MySQL accounts and remove unnecessary access.
