CVE-2026-47001: Oracle Enterprise Manager Auth Bypass Flaw

CVE-2026-47001 Overview

CVE-2026-47001 is an access control vulnerability [CWE-284] in the Web Services Framework component of Oracle Enterprise Manager Base Platform. Affected releases include versions 13.5 and 24.1. An authenticated attacker with low privileges and network access over HTTPS can compromise the platform without user interaction. Successful exploitation results in unauthorized read access to a subset of data and unauthorized update, insert, or delete access to some data. Oracle addressed the issue in the July 2026 Critical Patch Update.

Critical Impact
Low-privileged network attackers can modify and read a subset of Oracle Enterprise Manager Base Platform data via the Web Services Framework, undermining data integrity in enterprise monitoring environments.

Affected Products

Oracle Enterprise Manager Base Platform version 13.5
Oracle Enterprise Manager Base Platform version 24.1
Component: Web Services Framework

Technical Details for CVE-2026-47001

Vulnerability Analysis

The flaw resides in the Web Services Framework of Oracle Enterprise Manager Base Platform. It is classified under [CWE-284] Improper Access Control. The framework fails to enforce authorization checks consistently across exposed web service operations. An authenticated user with minimal role assignments can invoke operations that should be restricted to higher-privileged administrators.

Exploitation grants the attacker limited read visibility into Oracle Enterprise Manager data. It also allows modification, insertion, or deletion of a subset of managed data. Availability is not affected because the exposure is scoped to data operations rather than service disruption. The vulnerability is network-reachable over HTTPS and does not require user interaction.

Enterprise Manager typically holds sensitive configuration and telemetry for downstream Oracle databases, middleware, and infrastructure. Unauthorized writes into this control plane can cascade into monitoring blind spots or tampered audit records. The current EPSS probability sits at 0.24% at the 15th percentile, indicating low near-term exploitation likelihood.

Root Cause

The root cause is improper access control within web service endpoints. The framework authenticates the caller but does not fully validate that the caller is authorized for the specific operation or resource. Authorization decisions rely on incomplete role checks.

Attack Vector

The attacker requires network reachability to the Enterprise Manager HTTPS interface and valid low-privileged credentials. The attacker sends crafted requests to affected Web Services Framework endpoints. The server processes the request without applying the required authorization boundary, executing data operations on behalf of the attacker.

No verified proof-of-concept code has been published. The vulnerability is described in prose in the Oracle Critical Patch Update - July 2026 advisory.

Detection Methods for CVE-2026-47001

Indicators of Compromise

Unexpected INSERT, UPDATE, or DELETE operations in Enterprise Manager repository tables originating from low-privileged accounts.
Web service invocations from user sessions accessing endpoints outside their assigned role scope.
Anomalous HTTPS request volume to Enterprise Manager Web Services Framework URIs from a single authenticated principal.

Detection Strategies

Enable and review Oracle Enterprise Manager audit logs for authorization decisions and data modification events tied to Web Services Framework endpoints.
Correlate web service request logs with the caller's assigned Enterprise Manager role to flag privilege mismatches.
Baseline normal service consumption per user and alert on deviations that indicate enumeration or bulk modification.

Monitoring Recommendations

Forward Oracle HTTP Server access logs and Enterprise Manager audit logs to a centralized analytics platform for retention and correlation.
Monitor authentication events for low-privileged accounts followed by write operations against monitored targets.
Alert on modifications to Enterprise Manager metric thresholds, notification rules, or job definitions performed outside change windows.

How to Mitigate CVE-2026-47001

Immediate Actions Required

Apply the Oracle July 2026 Critical Patch Update to Enterprise Manager Base Platform 13.5 and 24.1 deployments.
Inventory all Enterprise Manager accounts and remove or downgrade unnecessary low-privileged users with network reach to the console.
Restrict network exposure of the Enterprise Manager HTTPS interface to trusted administrative networks and jump hosts.

Patch Information

Oracle released fixes as part of the July 2026 Critical Patch Update. Refer to the Oracle Critical Patch Update Advisory - July 2026 for the applicable bundle patches and prerequisites for Enterprise Manager 13.5 and 24.1.

Workarounds

Place the Enterprise Manager console behind network access controls that limit HTTPS reachability to a defined administrative subnet.
Rotate credentials for any low-privileged accounts that had access to the Web Services Framework prior to patching.
Enable Enterprise Manager fine-grained auditing to record web service invocations until the patch is fully deployed.

bash

# Example: restrict access to the Enterprise Manager HTTPS listener
# Replace 10.0.0.0/24 with your administrative CIDR range
iptables -A INPUT -p tcp --dport 7803 -s 10.0.0.0/24 -j ACCEPT
