Oracle Data Integrator Console Takeover Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-83397

The vulnerability affects the Oracle Data Integrator Console, which provides a web interface. While web consoles are frequently deployed in internal enterprise networks, they can be exposed to the internet depending on organizational configuration and access requirements. The network-accessible nature via HTTP suggests potential internet reachability, though it is not inherently a public-facing edge gateway by design.

Frequently asked questions

What is Oracle Data Integrator?

Oracle Data Integrator is a component of Oracle Fusion Middleware used for data integration and transformation. It enables organizations to manage complex data movement between different systems and databases. The Console and Repository Explorer are core interfaces used by administrators to monitor these integration workflows and manage the underlying repositories that store project metadata and configurations.

What does CVE-2026-83397 mean for the software?

This vulnerability represents a significant security weakness in the Console and Repository Explorer components of the software. Because the system fails to properly validate users, it allows an unauthenticated individual to perform unauthorized actions. This flaw is severe enough that it can lead to a complete takeover of the Oracle Data Integrator environment, affecting the confidentiality, integrity, and availability of your data.

How does an attacker trigger this vulnerability?

An attacker triggers this bug by sending crafted requests over HTTP to the affected console. Because the vulnerability does not require any prior authentication, anyone who can reach the service via the network can attempt the attack. It is important to note that internal actions or authorized administrative tasks within the console are not the cause of this issue; it is specifically the lack of access controls on the interface that enables the threat.

Is my Oracle Data Integrator instance at risk?

Your risk depends on how the Console is positioned on your network. According to Halo Surface Signal, this software provides a web interface that is often used internally but can be exposed to the internet. If your console is accessible over the internet, your risk is higher. You should assess whether your deployment is reachable from outside your protected network or if it is restricted to internal users.

What should I do if I run this software?

First, identify the specific versions of Oracle Data Integrator in your environment, focusing on 12.2.1.4.0 and 14.1.2.0.0. Once identified, determine the business criticality of those assets and confirm who owns them. Coordinate with your application teams to verify the network accessibility of the console and initiate a risk-based maintenance plan to apply the necessary updates from the vendor.
