CVE-2026-46989: Oracle Enterprise Manager Auth Bypass Flaw

CVE-2026-46989 Overview

CVE-2026-46989 is an improper access control vulnerability [CWE-284] in the UI Framework component of Oracle Enterprise Manager Base Platform. The flaw affects supported versions 13.5 and 24.1. A low-privileged attacker with network access via HTTPS can exploit this vulnerability to compromise Oracle Enterprise Manager Base Platform. The vulnerability carries a scope change, meaning successful exploitation impacts resources beyond the vulnerable component itself. Successful attacks can result in unauthorized access to critical data, unauthorized modification of some data, and partial denial of service conditions.

Critical Impact
Low-privileged network attackers can gain unauthorized access to all Oracle Enterprise Manager Base Platform accessible data with a scope change that extends impact to additional Oracle products.

Affected Products

Oracle Enterprise Manager Base Platform version 13.5
Oracle Enterprise Manager Base Platform version 24.1
Oracle Enterprise Manager (UI Framework component)

Technical Details for CVE-2026-46989

Vulnerability Analysis

The vulnerability resides in the UI Framework component of Oracle Enterprise Manager Base Platform. It is classified under [CWE-284] Improper Access Control. An attacker requires only low privileges and network access over HTTPS to exploit the flaw. No user interaction is required, and the attack complexity is low.

The scope change indicates that the vulnerable component acts as a pivot point. Exploitation from within the Enterprise Manager Base Platform can affect additional Oracle products managed by the platform. Enterprise Manager typically holds broad administrative reach across Oracle Database, Fusion Middleware, and infrastructure targets, amplifying the blast radius of a compromise.

Successful exploitation yields high confidentiality impact, allowing full read access to all data accessible to the platform. Integrity and availability impacts are limited to partial unauthorized modification and partial denial of service.

Root Cause

The root cause is improper enforcement of access controls within the UI Framework. Authorization checks fail to adequately restrict what a low-privileged authenticated user can request, allowing operations that should be gated behind higher privilege levels.

Attack Vector

An authenticated attacker sends crafted HTTPS requests to the Enterprise Manager UI Framework endpoints. Because privilege enforcement is deficient, the platform processes requests that reach protected functionality and data. The scope change reflects that resulting actions can traverse to managed targets. Refer to the Oracle Security Alert - July 2026 for vendor-authoritative details.

Detection Methods for CVE-2026-46989

Indicators of Compromise

Unexpected HTTPS requests to Enterprise Manager UI Framework endpoints originating from low-privileged accounts.
Audit log entries showing privileged operations initiated by non-administrative users.
Anomalous data export or query activity across managed Oracle targets from the Enterprise Manager service account.

Detection Strategies

Correlate Enterprise Manager audit logs with authentication events to identify privilege boundary violations.
Monitor for HTTPS session patterns that deviate from the baseline for standard operator accounts.
Alert on scope-crossing activity where Enterprise Manager reaches managed targets outside routine workflows.

Monitoring Recommendations

Ingest Enterprise Manager and OMS logs into a centralized SIEM for correlation with identity and network telemetry.
Track failed and successful access attempts against UI Framework URLs and flag privilege anomalies.
Establish behavioral baselines for administrative accounts and alert on deviations.

How to Mitigate CVE-2026-46989

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to affected Enterprise Manager 13.5 and 24.1 deployments.
Restrict network access to the Enterprise Manager console to trusted administrative networks only.
Review and reduce standing privileges for Enterprise Manager user accounts.
Rotate credentials and audit account entitlements after patching.

Patch Information

Oracle addressed CVE-2026-46989 in the July 2026 Critical Patch Update. Administrators should review and apply fixes documented in the Oracle Security Alert - July 2026 advisory for Enterprise Manager Base Platform 13.5 and 24.1.

Workarounds

Limit HTTPS access to the Enterprise Manager UI to a jump-host segment or VPN-only network path.
Disable or suspend low-privileged accounts that are not required for operations until patches are deployed.
Enable full audit logging on the Enterprise Manager Management Service and forward logs to an external collector.

bash

# Configuration example - restrict OMS console access at the reverse proxy
# Allow only administrative subnet to reach the Enterprise Manager UI
<Location />
    Require ip 10.20.30.0/24
    Require all denied
</Location>
