CVE-2022-21510: Vulnerability in the Oracle Database - Enterprise Edition Sharding component of Oracle Database Server.

Vulnerability in the Oracle Database - Enterprise Edition Sharding component of Oracle Database Server. For supported versions that are affected see note. Easily exploitable vulnerability allows low privileged attacker having Local Logon privilege with logon to the infrastructure where Oracle Database - Enterprise Edition Sharding executes to compromise Oracle Database - Enterprise Edition Sharding. While the vulnerability is in Oracle Database - Enterprise Edition Sharding, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Database - Enterprise Edition Sharding. Note: None of the supported versions are affected. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

Security readout for executives and security teams

Plain-English summary

This Oracle Database Enterprise Edition Sharding flaw could allow a low-privileged local user on the database infrastructure to take over the sharding component. Oracle’s CVE text states no supported versions are affected, so business urgency depends on whether legacy or unsupported sharding deployments exist.

Executive priority

Prioritize confirmation, not emergency disruption. If all Oracle sharding deployments are supported, the cited exposure is likely minimal. If unsupported sharding infrastructure exists, treat remediation as high priority because successful compromise is described as full takeover.

Technical view

CVE-2022-21510 affects Oracle Database Enterprise Edition Sharding. The CVSS vector is local, low complexity, low privileges, no user interaction, scope changed, with high confidentiality, integrity, and availability impact. The source bundle lists affected versions as None and says supported versions are not affected.

Likely exposure

Exposure appears limited to environments running Oracle Database Enterprise Edition Sharding on unsupported or legacy versions, with attackers already able to log on locally to the infrastructure where the component executes.

Exploitation context

No provided source reports active exploitation, and CISA KEV status is false. The vulnerability is locally exploitable after low-privileged logon, so risk is higher where database hosts have broad shell, service, or contractor access.

Researcher notes

Key uncertainty is version detail: the CVE description says supported versions are not affected and the affected list contains None. Do not infer internet exposure or remote exploitability; the vector is local with required low privileges.

Mitigation direction

  • Verify Oracle Database deployments are on supported versions.
  • Review Oracle’s July 2022 CPU guidance for this CVE.
  • Reduce local logon access to database sharding hosts.
  • Retire or upgrade unsupported Oracle sharding deployments.
  • Monitor Oracle advisories for any product-specific guidance.

Validation and detection

  • Inventory Oracle Database Enterprise Edition Sharding usage.
  • Confirm database versions and support status.
  • Identify local accounts with logon rights on sharding infrastructure.
  • Review whether unsupported sharding components remain active.
  • Check access logs for unexpected local logons.
