The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires the attacker to already have an authenticated low-privileged local logon to the infrastructure where Oracle BI EE executes (AV:L, PR:L) - there is no remote or unauthenticated path. Only version 12.2.1.4.0 of Oracle Business Intelligence Enterprise Edition is stated as affected, via the BI Foundation component. A significant limiting factor is high attack complexity (AC:H): success depends on conditions beyond the attacker's direct control (such as specific timing, state, or configuration), which meaningfully reduces reliability of exploitation. No user interaction is required (UI:N). Realistic risk is therefore concentrated on hosts where untrusted or semi-trusted users hold local accounts.

Impact

This is a high-CVSS (7.0) but realistically moderate-urgency issue. The Oracle-supplied CVSS 3.1 vector (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) tells a consistent story that tempers the full C:H/I:H/A:H 'takeover' impact: the attacker must already have local logon access to the host where Oracle BI EE runs (AV:L), must already hold low-level privileges (PR:L), AND must overcome high attack complexity (AC:H), meaning conditions outside the attacker's control (timing, configuration, or specific state) are required. No EPSS score was provided, so exploitation probability cannot be quantified. The CVE is NOT in CISA KEV and no public POC was supplied, so exploitation status is 'no public exploit identified at time of analysis.' No SSVC decision data was provided. The combined signals - local vector, prerequisite privileges, and high complexity - strongly indicate this is an insider/post-compromise privilege-escalation-to-takeover scenario rather than an internet-facing, mass-exploitable flaw. It belongs in the normal Oracle quarterly CPU patch cycle rather than emergency out-of-band remediation, unless the BI EE host is multi-tenant or exposes shell/logon access to many low-trust users.

Exploit ScenarioDerived

An attacker who already holds a low-privileged local account on the server hosting Oracle Business Intelligence Enterprise Edition leverages a flaw in the BI Foundation component to escalate to full compromise of the BI EE instance, gaining control over its confidentiality, integrity, and availability. No public exploit code is known, and the high attack complexity (AC:H) means the attacker must satisfy additional non-trivial conditions to succeed. This is a post-authentication, local-access scenario rather than a remote drive-by.

AnalysisAIv1 – Oct 20, 2026

Takeover of Oracle BI EE 12.2.1.4.0 is possible for an authenticated, low-privileged attacker who already has local logon to the infrastructure hosting the BI Foundation component, though high attack complexity makes reliable exploitation dependent on conditions beyond the attacker's control. The issue carries CVSS 3.1 base score 7.0 with full confidentiality, integrity, and availability impact, but it is not remotely or unauthenticated exploitable. No public exploit is identified at time of analysis, so risk is concentrated on hosts where semi-trusted users hold local accounts.

RemediationAI

Patch available per vendor advisory: Oracle Critical Patch Update October 2026. Apply that update using https://www.oracle.com/security-alerts/cpuoct2026.html; no exact patched build number is provided in the input, so confirm the fixed 12.2.1.4.0 build from Oracle before closing the finding. Because exploitation requires an authenticated local logon, reduce exposure by restricting interactive local access to BI EE hosts to trusted administrators, removing unnecessary local accounts, enforcing MFA and privileged-access management, and monitoring local logon and BI Foundation activity. If patching must be delayed, segment BI servers from general user workstation networks and limit local shell or application-server access; these controls can disrupt administrator workflows and integration accounts, so validate them against operational requirements.

Technical ContextAI · show details

Oracle Business Intelligence Enterprise Edition is an analytics platform; the affected BI Foundation component runs on the infrastructure where BI EE executes, and the CVSS vector (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) confines the attack path to a local, authenticated low-privileged user with no user interaction. The high attack complexity (AC:H) means successful exploitation depends on timing, state, or configuration conditions outside the attacker's direct control, reducing repeatability. No CWE is provided, and no CPE string is included in the input, so the exact affected build mapping is limited to the stated 12.2.1.4.0 release; the 'Information Disclosure' tag is broader than the vector's full C/I/A impact and should not be read as limiting the outcome to data exposure alone.

DescriptionCVE.org

Vulnerability in the Oracle Business Intelligence Enterprise Edition product of Oracle Analytics (component: BI Foundation). The supported version that is affected is 12.2.1.4.0. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Business Intelligence Enterprise Edition executes to compromise Oracle Business Intelligence Enterprise Edition. Successful attacks of this vulnerability can result in takeover of Oracle Business Intelligence Enterprise Edition. CVSS 3.1 Base Score 7.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).

Executive ViewAI

Why It Matters

Oracle BI EE 12.2.1.4.0 (BI Foundation) carries a high-severity vulnerability that could allow takeover of the component with full confidentiality, integrity, and availability impact on affected hosts. Risk is concentrated on infrastructure where semi-trusted users hold local accounts, and no public exploit identified at time of analysis. Leadership should care because a successful compromise could expose or corrupt business intelligence data and disrupt reporting, even though exploitation is not broadly remote.

Business Impact: Medium
Compensating Controls

No vendor-released patch identified at time of analysis; restrict local logon to BI Foundation hosts, enforce least privilege and remove unnecessary local accounts, segment hosts from broader networks, monitor for anomalous activity, and apply Oracle's recommended workarounds until a patch is available.

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
