CVE-2026-47005: Oracle Enterprise Manager Privilege Escalation

CVE-2026-47005 Overview

CVE-2026-47005 is a high-severity vulnerability in the Oracle Enterprise Manager Base Platform, part of Oracle Enterprise Manager. The flaw resides in the Self Update Framework component and affects supported versions 13.5 and 24.1. An authenticated attacker with high privileges and network access via HTTPS can exploit this issue to compromise the platform. Successful exploitation results in complete takeover of Oracle Enterprise Manager Base Platform, impacting confidentiality, integrity, and availability. Oracle addressed the flaw in the July 2026 Critical Patch Update. The weakness is categorized under [CWE-284] Improper Access Control.

Critical Impact
Successful exploitation allows a high-privileged attacker to fully take over Oracle Enterprise Manager Base Platform, compromising all managed targets and stored credentials.

Affected Products

Oracle Enterprise Manager Base Platform 13.5
Oracle Enterprise Manager Base Platform 24.1
Oracle Enterprise Manager Self Update Framework component

Technical Details for CVE-2026-47005

Vulnerability Analysis

The vulnerability affects the Self Update Framework in Oracle Enterprise Manager Base Platform. This framework retrieves and installs software updates, extensions, and metadata used to manage Oracle targets. Improper access control in this component allows a high-privileged authenticated user to abuse the update mechanism and gain full control of the Enterprise Manager instance.

Exploitation requires network access over HTTPS and valid high-privilege credentials. Attack complexity is low, and no user interaction is needed. Because Enterprise Manager centrally administers databases, middleware, and infrastructure, a successful takeover propagates trust across all managed targets.

The EPSS score is 0.342% with a percentile of 26.66, indicating limited active exploitation prediction at this time. No public proof of concept or CISA KEV listing has been reported.

Root Cause

The root cause is an improper access control weakness [CWE-284] in the Self Update Framework. Privileged operations exposed by the framework do not sufficiently enforce authorization boundaries, allowing a high-privileged user to reach functionality that should remain restricted to trusted internal update workflows.

Attack Vector

The attacker sends crafted HTTPS requests to the Enterprise Manager console using valid high-privileged credentials. By interacting with the Self Update Framework, the attacker manipulates update payloads or metadata handling to execute privileged actions. The resulting takeover grants control over the Enterprise Manager service and, by extension, all administered systems.

No verified exploit code is publicly available. Refer to the Oracle Security Alert - July 2026 for authoritative technical guidance.

Detection Methods for CVE-2026-47005

Indicators of Compromise

Unexpected Self Update Framework activity in Enterprise Manager audit logs, including update package imports from non-standard sources.
Creation or modification of Enterprise Manager plug-ins, metadata, or update entities outside scheduled maintenance windows.
Administrative account logins from unusual source addresses immediately preceding Self Update operations.

Detection Strategies

Correlate Enterprise Manager audit records with authentication logs to identify high-privileged sessions that trigger Self Update workflows.
Monitor OMS (Oracle Management Service) HTTPS request patterns for anomalous invocations of update-related endpoints.
Baseline normal Self Update usage and alert on deviations in frequency, source, or payload characteristics.

Monitoring Recommendations

Forward Oracle Enterprise Manager audit, OMS, and repository database logs to a centralized SIEM for correlation.
Enable file integrity monitoring on Enterprise Manager binaries, plug-in directories, and metadata staging paths.
Track privileged role assignments (EM_ALL_ADMINISTRATOR, SUPER_ADMIN) and alert on new grants.

How to Mitigate CVE-2026-47005

Immediate Actions Required

Apply the July 2026 Critical Patch Update from Oracle to Enterprise Manager 13.5 and 24.1 without delay.
Rotate credentials for all high-privileged Enterprise Manager administrator accounts after patching.
Review Self Update Framework audit history for suspicious activity dating back to before patch deployment.

Patch Information

Oracle released fixes as part of the July 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert - July 2026 for patch identifiers, download instructions, and version-specific application notes for Oracle Enterprise Manager Base Platform 13.5 and 24.1.

Workarounds

Restrict network access to the Enterprise Manager console to trusted management networks only.
Enforce least privilege on Enterprise Manager roles and reduce the number of accounts holding super administrator privileges.
Disable or tightly control the Self Update Framework until patches are applied where operationally feasible.

bash

# Configuration example - restrict console access at the OS firewall
# Allow only trusted management subnet to reach the OMS HTTPS port (default 7803)
iptables -A INPUT -p tcp --dport 7803 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 7803 -j DROP
