CVE-2026-83024: Oracle Identity Manager Privilege Escalation

CVE-2026-83024 Overview

CVE-2026-83024 is a high-severity vulnerability in the Oracle Identity Manager Connector, a component of Oracle Fusion Middleware. The flaw exists in the Core component and affects supported versions 12.2.1.4.0 and 14.1.2.1.0. A low-privileged attacker with local logon access to the infrastructure running Oracle Identity Manager Connector can exploit this weakness to fully compromise the product. Successful exploitation results in complete takeover, with full impact to confidentiality, integrity, and availability. The vulnerability is classified under CWE-284: Improper Access Control.

Critical Impact
Local attackers with valid logon credentials can take over Oracle Identity Manager Connector, gaining full control of identity provisioning workflows and downstream managed systems.

Affected Products

Oracle Identity Manager Connector 12.2.1.4.0
Oracle Identity Manager Connector 14.1.2.1.0
Oracle Fusion Middleware (Core component)

Technical Details for CVE-2026-83024

Vulnerability Analysis

CVE-2026-83024 resides in the Core component of Oracle Identity Manager Connector. The connector brokers identity data between Oracle Identity Manager and external target systems such as directories, databases, and SaaS applications. A compromise of this component grants an attacker control over provisioning, deprovisioning, and reconciliation flows.

The issue is exploitable by a low-privileged authenticated user on the host where the connector runs. No user interaction is required. Because the attack surface is local, the vulnerability is most relevant in multi-tenant middleware hosts, jump servers, and shared administrative environments where non-administrative accounts exist alongside the connector runtime.

Root Cause

Oracle categorizes the weakness under CWE-284: Improper Access Control. The connector fails to properly enforce access restrictions on a local interface, resource, or execution path. This gap allows a user without administrative rights to reach functionality that should be limited to privileged principals, leading to a full takeover of the connector process and its data.

Attack Vector

The attack path requires the adversary to hold local logon rights on the host running the connector. From that foothold, the attacker interacts with a locally accessible interface exposed by the connector to escalate control. Oracle has not published exploitation specifics beyond the advisory. Refer to the Oracle Security Alert CSPUSEP2026 for authoritative vendor guidance.

No public proof-of-concept exploit is available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS score is approximately 0.16%, indicating low near-term exploitation probability in the wild.

Detection Methods for CVE-2026-83024

Indicators of Compromise

Unexpected child processes spawned by the Oracle Identity Manager Connector runtime under non-administrative user contexts.
Modifications to connector configuration files, credential stores, or scheduled task definitions outside of change windows.
Anomalous provisioning or reconciliation events targeting privileged accounts in downstream managed systems.
Local logon activity from service or low-privilege accounts on Oracle Fusion Middleware hosts outside baseline patterns.

Detection Strategies

Monitor process lineage on middleware hosts for the connector JVM spawning shells, scripting interpreters, or network utilities.
Correlate local authentication events with subsequent access to Oracle Identity Manager Connector directories and binaries.
Alert on writes to connector installation paths, wallet files, and JAR/configuration artifacts by unauthorized principals.
Review Oracle Identity Manager audit logs for unusual policy, role, or entitlement changes originating from connector workflows.

Monitoring Recommendations

Enable file integrity monitoring on the Oracle Identity Manager Connector installation directory and configuration files.
Forward host authentication, process, and file telemetry from middleware servers to a centralized analytics platform.
Baseline connector service behavior and alert on deviations in outbound connections to managed target systems.
Track privileged group membership on middleware hosts and generate alerts on new local logon rights assignments.

How to Mitigate CVE-2026-83024

Immediate Actions Required

Apply the fixes referenced in the Oracle Security Alert CSPUSEP2026 to affected 12.2.1.4.0 and 14.1.2.1.0 deployments.
Inventory all hosts running Oracle Identity Manager Connector and confirm patch status across development, staging, and production tiers.
Restrict interactive and remote logon rights on connector hosts to a minimal set of administrators.
Rotate credentials, wallets, and secrets used by the connector after patching to invalidate any material an attacker may have accessed.

Patch Information

Oracle addresses CVE-2026-83024 in the security alert CSPUSEP2026. Administrators should review the advisory for the exact patch bundle, prerequisite Critical Patch Update levels, and post-installation validation steps. Only Oracle-supported versions receive fixes, so deployments on unsupported releases require an upgrade path before remediation is possible.

Workarounds

Remove local logon rights for non-essential accounts on hosts running Oracle Identity Manager Connector.
Segment middleware hosts on dedicated networks and enforce jump-host access for administrative operations.
Apply least-privilege file system permissions to the connector installation directory, configuration files, and credential stores.
Increase audit logging on the connector host and forward events to an external log store to preserve evidence if exploitation is attempted.

bash

# Configuration example: restrict access to the connector installation directory on Linux
# Replace /u01/oracle/idm-connector with your actual installation path
chown -R oracle:oinstall /u01/oracle/idm-connector
chmod -R 750 /u01/oracle/idm-connector
find /u01/oracle/idm-connector -type f -name '*.properties' -exec chmod 640 {} \;

# Enable auditd rules to track access to connector configuration
auditctl -w /u01/oracle/idm-connector -p rwxa -k oim_connector_access
