CVE-2021-2337: Vulnerability in the Oracle XML DB component of Oracle Database Server.

Vulnerability in the Oracle XML DB component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1 and 19c. Easily exploitable vulnerability allows high privileged attacker having Create Any Procedure, Create Public Synonym privilege with network access via Oracle Net to compromise Oracle XML DB. Successful attacks of this vulnerability can result in takeover of Oracle XML DB. CVSS 3.1 Base Score 7.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

Security readout for executives and security teams

Plain-English summary

This Oracle Database flaw could let a highly privileged database user take over the Oracle XML DB component remotely through Oracle Net. It is serious because a successful attack affects confidentiality, integrity, and availability, but it requires powerful privileges first.

Executive priority

Treat as high priority for Oracle environments with privileged database users or broad Oracle Net access. The prerequisite privileges reduce mass exploitation risk, but the impact is full takeover of a database component.

Technical view

CVE-2021-2337 affects Oracle XML DB in Oracle Database Enterprise Edition versions 12.1.0.2, 12.2.0.1, and 19c. The CVSS 3.1 score is 7.2, with network attack vector, low complexity, high privileges, no user interaction, and high CIA impact.

Likely exposure

Exposure is most likely where affected Oracle Database Enterprise Edition versions are reachable over Oracle Net and accounts exist with Create Any Procedure and Create Public Synonym privileges.

Exploitation context

The provided bundle does not show CISA KEV listing or cited evidence of active exploitation. The source describes easy exploitation only after the attacker already has high database privileges.

Researcher notes

The key constraint is privilege: exploitation requires a high privileged attacker with both named privileges and Oracle Net access. Sources do not provide CWE classification, exploit details, or independent exploitation confirmation.

Mitigation direction

  • Review Oracle's July 2021 Critical Patch Update for CVE-2021-2337 guidance.
  • Apply the relevant Oracle Database security updates for affected supported versions.
  • Restrict Oracle Net exposure to trusted administrative and application networks.
  • Review and reduce accounts with Create Any Procedure and Create Public Synonym privileges.
  • Monitor privileged database accounts for unusual procedure or synonym creation activity.

Validation and detection

  • Inventory Oracle Database Enterprise Edition instances and versions.
  • Confirm whether versions 12.1.0.2, 12.2.0.1, or 19c are present.
  • Check whether Oracle XML DB is installed or used on those instances.
  • Audit users granted Create Any Procedure and Create Public Synonym privileges.
  • Verify Oracle July 2021 CPU or later relevant fixes are applied.
