Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Fusion Middleware (component: Analytics Actions). Supported versions that are affected are 5.5.0.0.0, 12.2.1.3.0 and 12.2.1.4.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Business Intelligence Enterprise Edition, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Business Intelligence Enterprise Edition accessible data as well as unauthorized read access to a subset of Oracle Business Intelligence Enterprise Edition accessible data. CVSS 3.1 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

Security readout for executives and security teams

Plain-English summary

CVE-2021-2191 affects Oracle Business Intelligence Enterprise Edition. A low-privileged user who can reach the service over HTTP may, with another user's interaction, read or modify some BI-accessible data. The issue is medium severity, but it matters where OBIEE holds sensitive reports or trusted operational data.

Executive priority

Treat as a scheduled but visible remediation item. It is not known to be actively exploited from the supplied evidence, but it can affect BI data confidentiality and integrity where authenticated access is broad.

Technical view

The affected component is Analytics Actions in Oracle BI Enterprise Edition versions 5.5.0.0.0, 12.2.1.3.0, and 12.2.1.4.0. The CVSS vector is network exploitable, low complexity, low privileges required, user interaction required, changed scope, with low confidentiality and integrity impact and no availability impact.

Likely exposure

Exposure is most likely in organizations running the listed OBIEE versions with HTTP access available to authenticated low-privileged users. Risk increases if BI content includes sensitive, regulated, financial, or operational data.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The CVE description says exploitation is easy, requires low privileges, requires HTTP network access, and depends on human interaction from someone other than the attacker.

Researcher notes

No CWE is supplied in the bundle. The main security characteristics come from Oracle's CVSS vector: AV:N, AC:L, PR:L, UI:R, S:C, C:L, I:L, A:N. Avoid assuming exploit details beyond authenticated HTTP reachability and required user interaction.

Mitigation direction

  • Identify any OBIEE deployments running the affected versions.
  • Review Oracle's April 2021 CPU and current vendor guidance for applicable fixes.
  • Prioritize patching internet-facing or broadly accessible OBIEE instances.
  • Restrict OBIEE HTTP access to trusted networks and authorized users.
  • Review low-privileged BI accounts and remove unnecessary access.

Validation and detection

  • Inventory Oracle Business Intelligence Enterprise Edition versions in production and test environments.
  • Confirm whether Analytics Actions is present on affected deployments.
  • Check whether OBIEE HTTP endpoints are reachable from untrusted networks.
  • Review BI audit logs for unusual reads, updates, inserts, or deletes.
  • Verify vendor patch status against Oracle CPU guidance.
