CVE-2026-62597: Oracle Enterprise Manager Auth Bypass Flaw

CVE-2026-62597 Overview

CVE-2026-62597 is an improper access control vulnerability [CWE-284] in the Oracle Enterprise Manager Base Platform, specifically within the Event Management component. The flaw affects Oracle Enterprise Manager versions 13.5 and 24.1. A low-privileged attacker with network access via Simple Object Access Protocol (SOAP) can exploit the weakness to compromise the platform. Successful exploitation allows unauthorized creation, deletion, or modification of critical data across all Oracle Enterprise Manager Base Platform accessible data.

Critical Impact
Authenticated attackers can perform unauthorized write operations against critical Enterprise Manager data over the network through SOAP requests, undermining integrity of monitored infrastructure.

Affected Products

Oracle Enterprise Manager Base Platform version 13.5
Oracle Enterprise Manager Base Platform version 24.1
Event Management component of Oracle Enterprise Manager

Technical Details for CVE-2026-62597

Vulnerability Analysis

The vulnerability resides in the Event Management component of Oracle Enterprise Manager Base Platform. The component exposes SOAP endpoints that fail to enforce sufficient authorization checks on incoming requests. An attacker holding low-level credentials can issue crafted SOAP calls that bypass access control boundaries. The Common Weakness Enumeration classification [CWE-284] confirms the root issue is improper access control rather than an authentication bypass.

Exploitation impacts data integrity across the platform. Confidentiality and availability are not affected according to the CVSS impact metrics. However, an attacker can create, delete, or modify records that represent the operational state of monitored systems. This includes event definitions, incident rules, and monitoring configurations that administrators rely on for infrastructure oversight.

The Enterprise Prediction Scoring System (EPSS) probability for this vulnerability sits at a low baseline, though the requirement for only network access and low privileges keeps the attack surface broad in enterprise environments.

Root Cause

The root cause is missing or insufficient authorization enforcement on SOAP-accessible operations within the Event Management component. The Oracle Enterprise Manager Base Platform grants access to write operations without validating that the calling identity possesses the required privileges for the requested action.

Attack Vector

Exploitation requires network reachability to the Enterprise Manager SOAP interface and valid low-privileged credentials. The attacker sends SOAP requests directly to Event Management endpoints. No user interaction is required, and the attack does not require elevated privileges or complex conditions. Details of the vulnerable endpoints and payload structure are described in the Oracle Security Alert September 2026.

No public proof-of-concept exploit code has been verified at the time of this writing.

Detection Methods for CVE-2026-62597

Indicators of Compromise

Unexpected SOAP requests targeting Event Management endpoints on Oracle Enterprise Manager instances
Unauthorized creation, modification, or deletion of event rules, incident definitions, or monitoring targets
SOAP calls originating from low-privileged accounts performing write operations outside their normal role scope
Audit log gaps or anomalies around Event Management operations

Detection Strategies

Enable and review Oracle Enterprise Manager audit logging for all Event Management write operations
Baseline normal SOAP traffic patterns and alert on deviations in request volume, source, or operation type
Correlate authenticated user activity with the specific SOAP operations they invoke to identify privilege boundary violations
Monitor for configuration drift in event rules and incident management objects

Monitoring Recommendations

Forward Oracle Enterprise Manager audit logs to a centralized SIEM for long-term correlation and search
Alert on any modifications to Event Management objects performed by accounts not designated for administrative functions
Track SOAP request headers, source IP addresses, and authenticated principals for all Event Management endpoints

How to Mitigate CVE-2026-62597

Immediate Actions Required

Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert September 2026 to affected Oracle Enterprise Manager 13.5 and 24.1 installations
Inventory all Oracle Enterprise Manager instances and confirm patch status on each
Audit existing low-privileged accounts with network access to the Enterprise Manager platform
Review recent Event Management changes for unauthorized modifications prior to patching

Patch Information

Oracle released fixes as part of its September 2026 Critical Patch Update cycle. Administrators should consult the Oracle Security Alert September 2026 for version-specific patch identifiers and deployment guidance. Apply patches during a scheduled maintenance window and validate Enterprise Manager functionality after installation.

Workarounds

Restrict network access to Oracle Enterprise Manager SOAP endpoints using firewall rules or network segmentation until patches are applied
Enforce least-privilege principles on all Enterprise Manager user accounts and remove unnecessary low-privileged access
Enable comprehensive audit logging on the Event Management component to increase detection likelihood
Place Oracle Enterprise Manager management interfaces behind a bastion host or VPN accessible only to administrators

bash

# Example: restrict SOAP endpoint exposure with iptables
# Allow only trusted management subnet to reach OEM SOAP port
iptables -A INPUT -p tcp --dport 7802 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 7802 -j DROP
