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

Exploitation Conditions

The exposed attack surface is the Oracle Data Integrator Console / Repository Explorer reachable over HTTP; exploitation requires only network access to that web interface. Per the vendor vector (PR:N/UI:N/AC:L) there is no authentication, no user interaction, and no non-default configuration prerequisite stated - default network-exposed ODI Console deployments are at risk. The primary LIMITING factor is network exposure: instances where the ODI Console is restricted to internal/management networks or behind access controls are not remotely reachable by arbitrary attackers. Affected deployments are limited to Oracle Data Integrator versions 12.2.1.4.0 and 14.1.2.0.0.

Impact

This is a genuine high-priority vulnerability, not a high-CVSS-but-low-risk artifact. The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, base 9.8) describes the worst-case profile: network-reachable over HTTP, low attack complexity, no privileges, no user interaction, with full confidentiality, integrity, and availability loss culminating in product takeover. All three Oracle-defined signals point the same way and are internally consistent with the prose ('Easily exploitable... unauthenticated attacker with network access via HTTP... takeover'). However, several decision signals are MISSING from the input and must not be fabricated: no EPSS exploitation-probability score was supplied, there is no CISA KEV listing, no POC/exploit-code reference, and no SSVC decision record. Exploitation status is therefore 'no public exploit identified at time of analysis' - this is an absence of evidence, not evidence that exploitation is hard. For an unauthenticated 9.8 in Oracle middleware patched in a quarterly CPU, defenders should treat weaponization as a question of time and prioritize patching accordingly. One labeling caveat: the input Tags include 'Information Disclosure', which understates a vulnerability the vendor explicitly calls full 'takeover' (C:H/I:H/A:H) - see confidence_notes.

Exploit ScenarioDerived

An attacker with only network reachability to the Oracle Data Integrator Console / Repository Explorer sends a crafted HTTP request to the exposed web interface, requiring no credentials and no user interaction, and leverages the flaw to gain complete control of the ODI instance. Because ODI brokers data-integration jobs and repository credentials, takeover can expose or tamper with connected data stores. No public proof-of-concept or exploit code was identified in the provided intelligence.

AnalysisAIv1 – Oct 21, 2026

Unauthenticated remote takeover of Oracle Data Integrator 12.2.1.4.0 and 14.1.2.0.0 is possible through the ODI Console / Repository Explorer over HTTP, as addressed in Oracle's October 2026 Critical Patch Update. The CVSS 3.1 score is 9.8 with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, meaning no authentication, no user interaction, and high confidentiality, integrity, and availability impact. No public exploit code or CISA KEV confirmation was identified in the supplied intelligence at time of analysis, but internet-exposed ODI Console instances are high priority because the assessed limiting factor is network reachability rather than any special configuration.

RemediationAI

Patch available per vendor advisory: apply the Oracle Critical Patch Update for October 2026 to Oracle Data Integrator 12.2.1.4.0 and 14.1.2.0.0, following the instructions at https://www.oracle.com/security-alerts/cpuoct2026.html. Until patching is complete, restrict network access to the ODI Console / Repository Explorer so that only trusted management networks, VPN users, or an authenticated reverse proxy can reach it, and block direct HTTP access from the internet or untrusted segments; the trade-off is reduced remote availability for legitimate administrators. If the Console is not operationally required, undeploy or disable it at the web-container or Oracle HTTP Server layer, accepting the loss of that management interface. Where a reverse proxy or WAF is already in place, enforce authentication and allowlisting in front of the Console and review its logs for anomalous unauthenticated requests, understanding that these are compensating controls and not a substitute for the vendor patch.

Technical ContextAI · show details

Oracle Data Integrator is a Fusion Middleware data-integration and ETL platform whose Console / Repository Explorer is a web-facing administrative interface used to manage repositories, projects, mappings, sessions, and related metadata over HTTP. The supplied data does not assign a CWE, so the precise defect class - for example missing authentication, authorization bypass, or unsafe exposure of an administrative function - is not officially characterized; however, the CVSS vector establishes an unauthenticated, network-reachable compromise path in that web console layer with high impact across confidentiality, integrity, and availability. EUVD confirms the affected releases as 12.2.1.4.0 and 14.1.2.0.0; no CPE strings were supplied. Because the vulnerable surface is the ODI Console/Repository Explorer, exposure depends on whether that HTTP interface is reachable from untrusted networks rather than on a non-default product setting.

DescriptionCVE.org

Vulnerability in the Oracle Data Integrator product of Oracle Fusion Middleware (component: Console / Repository Explorer). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Data Integrator. Successful attacks of this vulnerability can result in takeover of Oracle Data Integrator. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Executive ViewAI

Why It Matters

Oracle Data Integrator 12.2.1.4.0 and 14.1.2.0.0 present a critical unauthenticated remote-takeover risk through ODI Console/Repository Explorer, which could expose data integration repositories and business-critical pipelines to compromise. Any internet-reachable instance should be treated as an urgent enterprise exposure because no credentials or user interaction are required, and no vendor-released patch was identified at time of analysis.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis; restrict network access to ODI Console/Repository Explorer through VPN/allowlisting, disable unnecessary HTTP exposure, segment affected systems, monitor for anomalous access, and rotate repository credentials.
