CVE-2026-47003: Oracle Enterprise Manager Auth Bypass Flaw

CVE-2026-47003 Overview

CVE-2026-47003 is an access control weakness [CWE-284] in the UI Framework component of Oracle Enterprise Manager Base Platform. The flaw affects supported versions 13.5 and 24.1. An unauthenticated attacker with network access via HTTPS can exploit the issue to compromise confidentiality of the platform. Oracle disclosed the vulnerability in the July 2026 Critical Patch Update.

Successful exploitation yields unauthorized access to critical data or complete access to all Oracle Enterprise Manager Base Platform accessible data. The attack targets confidentiality only, with no impact on integrity or availability. Exploitation is rated as difficult due to conditions outside the attacker's control.

Critical Impact
Unauthenticated network attackers can read all data accessible to Oracle Enterprise Manager Base Platform when exploitation conditions are met.

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-2026-47003

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. The weakness allows an unauthenticated remote attacker to reach protected data over HTTPS without valid credentials.

Exploitation carries high attack complexity, meaning the attacker must satisfy conditions outside their direct control. When conditions are met, the attacker gains read access to all data reachable by the platform. The scope is unchanged, so impact is confined to the vulnerable component's authorization boundary.

The EPSS probability is 0.318% at the 24th percentile, reflecting low observed exploitation likelihood at this time.

Root Cause

The root cause is improper access control in the UI Framework request handling logic. The component fails to enforce authorization checks under specific conditions, permitting anonymous callers to reach data endpoints that should require authenticated sessions. Oracle has not published component-level technical details beyond the advisory.

Attack Vector

The attack vector is network-based over HTTPS. An unauthenticated adversary sends crafted requests to the Oracle Enterprise Manager Base Platform web interface. User interaction is not required. The attacker must trigger the specific conditions that bypass the access control check to obtain data. Refer to the Oracle Security Alert July 2026 for advisory-level details.

No verified public proof-of-concept code is available. Technical exploitation details are not published by Oracle beyond the advisory.

Detection Methods for CVE-2026-47003

Indicators of Compromise

Unauthenticated HTTPS requests to Oracle Enterprise Manager UI Framework endpoints returning sensitive response payloads
Anomalous data-volume responses from Enterprise Manager web endpoints to external or unexpected source addresses
Access log entries showing requests to protected UI Framework paths without valid session cookies or authentication headers

Detection Strategies

Inspect Oracle Enterprise Manager access logs for requests to UI Framework URLs lacking authentication tokens
Correlate outbound response sizes from the Enterprise Manager host against baseline traffic to identify data exfiltration attempts
Alert on repeated HTTPS requests from a single source that enumerate Enterprise Manager endpoints

Monitoring Recommendations

Enable verbose HTTP access logging on the Enterprise Manager Oracle HTTP Server tier and forward to a central SIEM
Monitor for privileged data queries and export activity originating from the Enterprise Manager repository outside change windows
Track authentication failures and anonymous session creation attempts against the management console

How to Mitigate CVE-2026-47003

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to Oracle Enterprise Manager Base Platform 13.5 and 24.1 without delay
Restrict network access to the Enterprise Manager console to trusted management networks using firewall rules or reverse-proxy allowlists
Audit recent access logs for anomalous unauthenticated requests to UI Framework endpoints

Patch Information

Oracle addressed CVE-2026-47003 in the July 2026 Critical Patch Update. Administrators should download and install the patches referenced in the Oracle Security Alert July 2026. Verify that the patch level is reflected in the OMS home inventory after application.

Workarounds

Place the Enterprise Manager console behind a VPN or bastion host to eliminate direct internet exposure
Enforce network segmentation so only authorized administrator subnets can reach TCP ports used by the OMS console
Require mutual TLS or an authenticating reverse proxy in front of the Enterprise Manager UI to block anonymous callers until patching completes
