Security readout for executives and security teams
Plain-English summary
CVE-2021-2152 affects Oracle Business Intelligence Enterprise Edition. An already highly privileged attacker with HTTP network access and help from another user could read or change some OBIEE-accessible data. The score is moderate because exploitation is difficult and requires privileges and user interaction, but the scope may extend beyond OBIEE.
Executive priority
Treat as a scheduled remediation item for affected OBIEE environments. Escalate if OBIEE handles sensitive reporting data, is broadly reachable, or has many privileged users.
Technical view
Oracle describes this as an Analytics Web General flaw in OBIEE versions 5.5.0.0.0, 11.1.1.9.0, 12.2.1.3.0, and 12.2.1.4.0. CVSS 3.1 is 4.0: AV:N/AC:H/PR:H/UI:R/S:C/C:L/I:L/A:N. Impacts are limited confidentiality and integrity, with no availability impact stated.
Likely exposure
Exposure is limited to organizations running the listed OBIEE versions, especially where privileged users can reach the application over HTTP. Internet exposure is not required by the source, but any reachable OBIEE deployment increases concern.
Exploitation context
The provided sources do not show active exploitation, and this CVE is not marked KEV. Oracle states exploitation is difficult, requires high privileges, network access via HTTP, and human interaction from someone other than the attacker.
Researcher notes
No CWE is provided in the bundle. The important details are high attack complexity, required high privileges, required user interaction, changed scope, and limited confidentiality and integrity impact. Evidence is insufficient to claim exploit availability or a specific root cause.
Mitigation direction
- Review Oracle’s April 2021 Critical Patch Update guidance for CVE-2021-2152.
- Apply Oracle-recommended updates or remediation for affected OBIEE versions.
- Restrict HTTP access to OBIEE to required trusted users and networks.
- Review privileged OBIEE accounts for unnecessary access.
Validation and detection
- Inventory OBIEE deployments and compare versions against the affected list.
- Confirm whether Oracle April 2021 CPU remediation was applied.
- Check whether OBIEE is reachable over HTTP from untrusted networks.
- Review logs for unusual privileged data read or update activity.
