CVE-2026-46792: Oracle Identity Manager Auth Bypass Flaw

CVE-2026-46792 Overview

CVE-2026-46792 is a critical vulnerability in the Oracle Identity Manager Connector, 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 HTTP can exploit this weakness to take over the Identity Manager Connector. The vulnerability carries a scope change, meaning successful exploitation can impact additional downstream products beyond the connector itself. Oracle classifies the issue under improper access control [CWE-284].

Critical Impact
Attackers with low-privileged HTTP access can fully compromise Oracle Identity Manager Connector, with cascading impact on integrated identity-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 (Generic Unix Connector component)

Technical Details for CVE-2026-46792

Vulnerability Analysis

The Oracle Identity Manager Connector provides integration between Oracle Identity Manager and external target systems. The Generic Unix Connector specifically manages user provisioning, deprovisioning, and account reconciliation against Unix-based hosts. CVE-2026-46792 stems from improper access control [CWE-284] within this connector. An authenticated attacker holding only low privileges can issue HTTP requests that bypass authorization checks and reach privileged functionality. Because identity connectors broker credentials and account operations across many downstream systems, a compromise here propagates outward.

Root Cause

The root cause is insufficient access control enforcement on connector operations exposed over HTTP. Oracle's advisory indicates that the vulnerability allows a low-privileged actor to perform actions reserved for higher-privileged roles. The scope change designation in the CVSS vector confirms that the security boundary breached inside the connector grants influence over resources owned by other components, including the identity-managed downstream Unix systems.

Attack Vector

Exploitation requires network reachability to the connector's HTTP interface and an authenticated account with low privileges. No user interaction is required. An attacker authenticates, sends crafted HTTP requests against the connector endpoint, and triggers privileged actions that lead to full takeover. From there, the attacker can pivot into target Unix systems managed by the connector, manipulate account lifecycle operations, and exfiltrate or alter sensitive identity data.

No verified public proof-of-concept code is available at this time. Refer to the Oracle Critical Security Patch Update Advisory for vendor-supplied technical context.

Detection Methods for CVE-2026-46792

Indicators of Compromise

Unexpected HTTP requests against Oracle Identity Manager Connector endpoints originating from low-privileged service accounts.
New or modified Unix accounts created on target systems outside of approved change windows.
Connector audit log entries showing privileged operations executed by accounts that historically performed only read operations.
Outbound connections from the Identity Manager Connector host to non-standard administrative destinations.

Detection Strategies

Inspect Oracle Identity Manager audit and connector logs for authorization failures followed by successful privileged actions from the same session.
Baseline normal HTTP request patterns to the connector and alert on deviations in request method, URI, or volume.
Correlate identity provisioning events across the Identity Manager Connector and downstream Unix systems to detect out-of-band account changes.

Monitoring Recommendations

Forward Oracle Fusion Middleware and Identity Manager Connector logs to a centralized SIEM with retention sufficient for retrospective investigation.
Monitor authentication events for low-privileged accounts that suddenly initiate connector administrative operations.
Track configuration changes to Generic Unix Connector resource objects and IT resource definitions in near real time.

How to Mitigate CVE-2026-46792

Immediate Actions Required

Apply the Oracle Critical Patch Update from June 2026 to all affected Identity Manager Connector deployments without delay.
Inventory all instances of Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0 and confirm patch status.
Restrict network access to the connector's HTTP interface to trusted management networks only.
Review and reduce the population of low-privileged accounts that can authenticate to the connector.

Patch Information

Oracle addressed CVE-2026-46792 in the June 2026 Critical Security Patch Update. Administrators should consult the Oracle Security Alert for the specific patch identifiers and installation procedures applicable to versions 12.2.1.4.0 and 14.1.2.1.0.

Workarounds

Place the Identity Manager Connector behind a reverse proxy or web application firewall that enforces strict authorization on connector URIs until patching is complete.
Temporarily disable unused Generic Unix Connector endpoints and resource objects to shrink the attack surface.
Rotate credentials used by the connector to manage downstream Unix systems after patching to invalidate any keys an attacker may have harvested.

bash

# Configuration example: restrict access to the connector HTTP endpoint at the network layer
# Replace 10.0.0.0/24 with your trusted administrative subnet
iptables -A INPUT -p tcp --dport 14000 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 14000 -j DROP
