CVE-2026-46794: Oracle Identity Manager Connector Vuln

CVE-2026-46794 Overview

CVE-2026-46794 is a privilege escalation vulnerability in the Oracle Identity Manager Connector product, part of Oracle Fusion Middleware. The flaw resides in the Generic Unix Connector component and affects supported versions 12.2.1.4.0 and 14.1.2.1.0. A low-privileged attacker with network access via SSH can exploit this issue to compromise the Identity Manager Connector. The vulnerability carries a scope change, meaning successful exploitation can impact resources beyond the vulnerable component. Oracle disclosed the issue in its June 2026 Critical Patch Update.

Critical Impact
Successful exploitation results in complete takeover of the Identity Manager Connector with high impact on confidentiality, integrity, and availability across connected systems.

Affected Products

Oracle Identity Manager Connector 12.2.1.4.0
Oracle Identity Manager Connector 14.1.2.1.0
Oracle Fusion Middleware deployments using the Generic Unix Connector component

Technical Details for CVE-2026-46794

Vulnerability Analysis

The vulnerability resides in the Generic Unix Connector component used by Oracle Identity Manager Connector to provision and manage identities on Unix-based target systems via SSH. An authenticated attacker holding low privileges can leverage network-accessible SSH functionality to subvert the connector's privilege boundaries. The flaw is mapped to [CWE-269] Improper Privilege Management, indicating the connector does not correctly assign, track, or enforce privileges during SSH-based identity operations. Exploitation requires no user interaction and is rated as low complexity by Oracle. The scope change attribute is particularly relevant: a compromise of the connector affects downstream systems the connector manages, including Unix hosts and identity stores. The EPSS probability is 0.432%, placing the CVE in the 34th percentile for predicted exploitation likelihood.

Root Cause

The root cause is improper privilege management in how the Generic Unix Connector authenticates and authorizes operations over SSH. The connector likely fails to enforce least-privilege controls between the requesting principal and the SSH session executing privileged identity operations on target Unix systems.

Attack Vector

An attacker with a low-privileged account and network reachability to the connector's SSH interface sends crafted requests that escalate the executing context. Because Oracle Identity Manager Connector orchestrates identity changes across multiple downstream systems, the compromise propagates beyond the connector itself.

No public proof-of-concept code is available at the time of publication. Refer to the Oracle Security Alert for vendor-provided technical context.

Detection Methods for CVE-2026-46794

Indicators of Compromise

Unexpected SSH sessions originating from or terminating at the Oracle Identity Manager Connector host outside normal provisioning windows.
Identity provisioning or reconciliation jobs executed by accounts that do not normally trigger such operations.
Newly created or modified privileged Unix accounts on target systems managed by the connector without a corresponding change ticket.
Anomalous outbound connections from the connector to hosts not defined in connector configuration.

Detection Strategies

Audit Oracle Identity Manager Connector logs for low-privileged users invoking Generic Unix Connector operations that result in elevated actions on target hosts.
Correlate SSH authentication logs on Unix targets with connector audit logs to identify operations that bypass expected approval workflows.
Monitor for connector configuration changes, new connector instances, or modifications to SSH credentials stored in the connector.

Monitoring Recommendations

Forward Oracle Fusion Middleware and connector logs to a centralized log analytics platform for retention and correlation.
Establish baselines for normal connector activity volumes and alert on statistically significant deviations.
Enable detailed SSH session logging on Unix hosts targeted by the connector and review privileged command execution.

How to Mitigate CVE-2026-46794

Immediate Actions Required

Apply the fixes published in the Oracle June 2026 Critical Patch Update to Oracle Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0 as soon as possible.
Inventory all Identity Manager Connector deployments and verify which use the Generic Unix Connector component.
Rotate SSH credentials and service account passwords used by the connector after patching.
Restrict network access to connector management interfaces to a defined administrative network segment.

Patch Information

Oracle has released remediation in the June 2026 Critical Patch Update. Patch details and download links are available in the Oracle Security Alert. Administrators should apply the patch in non-production environments first and validate identity provisioning workflows before production rollout.

Workarounds

If immediate patching is not feasible, restrict SSH and management network access to the Identity Manager Connector to trusted administrative hosts only.
Reduce the privileges of accounts permitted to interact with the connector to the minimum required for operations.
Temporarily disable the Generic Unix Connector component where it is not actively required for identity provisioning.
Increase audit logging on the connector and on all downstream Unix systems it manages.

bash

# Example: restrict inbound SSH to the Identity Manager Connector host
# Replace 10.10.10.0/24 with your administrative network CIDR
iptables -A INPUT -p tcp --dport 22 -s 10.10.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j DROP
