CVE-2022-21555: Vulnerability in the MySQL Shell for VS Code product of Oracle MySQL (component: Shell: GUI).

Vulnerability in the MySQL Shell for VS Code product of Oracle MySQL (component: Shell: GUI). Supported versions that are affected are 1.1.8 and prior. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where MySQL Shell for VS Code executes to compromise MySQL Shell for VS Code. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in MySQL Shell for VS Code, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Shell for VS Code accessible data as well as unauthorized read access to a subset of MySQL Shell for VS Code accessible data. CVSS 3.1 Base Score 4.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2022-21555 affects Oracle MySQL Shell for VS Code 1.1.8 and earlier. An attacker already logged into the same infrastructure with high privileges could, with another user's interaction, read or change some data accessible through the tool. Business impact is limited but relevant where privileged database tooling is used on shared or sensitive workstations.

Executive priority

Treat as a targeted workstation and administration-tool risk, not an internet-wide emergency. Prioritize remediation where privileged users manage sensitive MySQL data or use shared infrastructure.

Technical view

The source describes a local, low-complexity issue in MySQL Shell for VS Code Shell GUI with high privileges and required user interaction. CVSS is 4.2, with low confidentiality and integrity impact, no availability impact, and scope change, meaning effects may extend beyond the vulnerable component.

Likely exposure

Exposure is most likely on developer, DBA, or operations systems running MySQL Shell for VS Code 1.1.8 or earlier, especially where multiple privileged users access shared infrastructure.

Exploitation context

The source bundle does not identify active exploitation, and CISA KEV status is false. Exploitation requires local infrastructure logon, high privileges, and human interaction from another person.

Researcher notes

The source names MySQL Shell for VS Code and component Shell: GUI, but the affected product field lists MySQL Server. The bundle provides no CWE, root-cause detail, exploit evidence, or fixed version, so validation should anchor on Oracle's advisory and local version inventory.

Mitigation direction

  • Inventory MySQL Shell for VS Code installations and identify versions 1.1.8 or earlier.
  • Review Oracle's July 2022 Critical Patch Update guidance for the vendor-supported fix.
  • Upgrade or remove affected installations according to Oracle guidance.
  • Restrict privileged local logon access on systems running database administration tooling.
  • Avoid shared privileged workstations for database management workflows.

Validation and detection

  • Confirm installed MySQL Shell for VS Code versions across developer and DBA endpoints.
  • Verify affected instances have been upgraded or removed per Oracle guidance.
  • Check whether privileged local access is limited to approved administrators.
  • Confirm users understand prompts or interactions involving database tooling on shared infrastructure.
