CVE-2022-21535: Vulnerability in the MySQL Shell product of Oracle MySQL (component: Shell: General/Core Client).

Vulnerability in the MySQL Shell product of Oracle MySQL (component: Shell: General/Core Client). Supported versions that are affected are 8.0.28 and prior. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where MySQL Shell executes to compromise MySQL Shell. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Shell. CVSS 3.1 Base Score 2.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L).

Security readout for executives and security teams

Plain-English summary

CVE-2022-21535 is a low-severity Oracle MySQL Shell issue. An attacker who can log on to the system where MySQL Shell runs may, with user interaction and difficult conditions, cause a partial denial of service of MySQL Shell. The sources do not indicate data theft, data modification, or active exploitation.

Executive priority

Treat as routine remediation, not an emergency. The business risk is limited because the issue requires local infrastructure access, difficult exploitation, user interaction, and affects availability only. Include it in standard Oracle/MySQL patch cycles, especially for privileged database management environments.

Technical view

Oracle describes a vulnerability in MySQL Shell, Shell: General/Core Client, affecting supported versions 8.0.28 and prior. CVSS 3.1 is 2.5: local attack vector, high complexity, no privileges, required user interaction, unchanged scope, and low availability impact only.

Likely exposure

Exposure is most likely on admin workstations, jump hosts, automation runners, or database management systems where MySQL Shell 8.0.28 or earlier is installed or executed. The attacker must have logon access to that infrastructure, so internet-exposed risk is not supported by the sources.

Exploitation context

The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Exploitation is described as difficult and requiring human interaction from someone other than the attacker. Impact is limited to partial denial of service of MySQL Shell.

Researcher notes

Evidence is limited to the CVE description and Oracle CPU reference. The affected data in the bundle names MySQL Server, while the description and title identify MySQL Shell. Validate asset matching carefully and avoid assuming broader MySQL Server exposure without vendor confirmation.

Mitigation direction

  • Inventory systems running MySQL Shell 8.0.28 or earlier.
  • Apply Oracle July 2022 CPU guidance or later vendor-supported MySQL Shell updates.
  • Restrict logon access to hosts where MySQL Shell runs.
  • Prioritize database administration and automation hosts first.
  • Review Oracle guidance for any environment-specific instructions.

Validation and detection

  • Confirm installed MySQL Shell versions on managed hosts.
  • Verify affected hosts are updated beyond vendor-identified affected versions.
  • Check administrative hosts for unnecessary local user access.
  • Confirm vulnerability management records track this CVE to closure.
  • Review operational logs for unexplained MySQL Shell crashes or disruptions.
