CVE-2022-21550: Vulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General).

Vulnerability in the MySQL Cluster product of Oracle MySQL (component: Cluster: General). Supported versions that are affected are 7.4.36 and prior, 7.5.26 and prior, 7.6.22 and prior and and 8.0.29 and prior. Difficult to exploit vulnerability allows high privileged attacker with access to the physical communication segment attached to the hardware where the MySQL Cluster executes to compromise MySQL Cluster. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of MySQL Cluster. CVSS 3.1 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H).

Security readout for executives and security teams

Plain-English summary

CVE-2022-21550 affects Oracle MySQL Cluster and can lead to full cluster takeover. The business risk is serious where MySQL Cluster is used, but the attack path is constrained: high privileges, access to the physical communication segment, high complexity, and separate user interaction are required.

Executive priority

Treat as a targeted remediation item, not an internet-wide emergency. Prioritize affected production clusters because successful exploitation can take over MySQL Cluster despite the difficult prerequisites.

Technical view

Oracle describes a Cluster: General vulnerability in MySQL Cluster versions 7.4.36 and prior, 7.5.26 and prior, 7.6.22 and prior, and 8.0.29 and prior. CVSS 3.1 is 6.3 with adjacent access, high complexity, high privileges, required user interaction, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is likely limited to organizations running affected MySQL Cluster versions, especially where cluster communication networks are reachable by privileged users or poorly segmented infrastructure operators.

Exploitation context

The source bundle does not indicate CISA KEV listing or active exploitation. Exploitation is described as difficult and requires high privileges, physical communication segment access, and human interaction from another person.

Researcher notes

The sources provide affected version ranges, CVSS vector, impact, and exploit prerequisites, but not detailed root cause, exploit evidence, or exact fixed build mapping in the bundle. Avoid assuming broader MySQL Server exposure.

Mitigation direction

  • Identify all Oracle MySQL Cluster deployments and versions.
  • Review Oracle July 2022 CPU guidance for the applicable fixed release.
  • Prioritize upgrade or remediation for affected production clusters.
  • Restrict access to MySQL Cluster physical communication segments.
  • Review NetApp advisory if using NetApp products with MySQL Cluster exposure.

Validation and detection

  • Confirm whether MySQL Cluster is deployed in the environment.
  • Compare deployed versions against affected version ranges.
  • Verify cluster communication segments are restricted to required systems and administrators.
  • Check patch records against Oracle July 2022 CPU guidance.
  • Document any compensating controls for systems awaiting remediation.
