CVE-2025-61884: Oracle E-Business Suite Vulnerability and Recommended Actions

Overview

On October 11th, Oracle announced CVE-2025-61884, a high-severity vulnerability in Oracle E-Business Suite (EBS) affecting versions 12.2.3 to 12.2.14.


The issue exists in the Oracle Configurator (Runtime UI) component and can be exploited remotely without authentication, allowing attackers to access sensitive resources over the network without credentials.

CVSS v3.1 Score: 7.5 (High)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: High risk to confidentiality

Oracle has addressed this vulnerability in the July 2025 Critical Patch Update (CPU).
If you are running Oracle E-Business Suite, apply the latest security patch immediately or implement the configuration mitigations listed below.

Why It Matters

This vulnerability allows attackers to directly access the Configurator Runtime UI and potentially retrieve or manipulate sensitive business data.

Key points:

  • Remote and unauthenticated: No login required for exploitation.

  • HTTP/HTTPS both affected: Using TLS alone does not prevent the attack.

  • High confidentiality risk: Sensitive data may be exposed.

  • Common exposure scenario: Internet-facing EBS web tiers or unused components left enabled.

Even if your organization does not use Oracle Configurator, keeping it enabled unnecessarily increases your attack surface.

Immediate Actions to Take

A. Apply the July 2025 Security Patch

The July 2025 Critical Patch Update (CPU) includes the fix for CVE-2025-61884.

  • Download and apply the patch from My Oracle Support for your specific EBS version (12.2.3–12.2.14).

  • Always test the patch in a non-production environment before deploying it to production.

Configuration Hardening Steps

1. Use the Secure Configuration Console

Run the Secure Configuration Console and verify that:

  • Critical security profile values are properly set.

  • Allowed Resources is enabled.

  • Unused resources are marked as denied.

2. Configure Allowed Resources

The Allowed Resources feature defines which EBS products are permitted to run.

  • Enable this feature and disable unused components, especially Oracle Configurator if it’s not used.

Steps to disable Configurator:

  1. Go to Management by Product Hierarchy → Order Management & Logistics → Configurator.

  2. Deselect Enable and click Apply.

3. Verify DMZ and Web Tier Configuration

If any part of EBS is exposed through a DMZ:

  • Confirm the URL firewall is enabled in url_fw.conf under Oracle HTTP Server (OHS).

  • Follow Oracle’s DMZ configuration guides:

    • Doc ID 1375670.1 (EBS 12.2)

    • Doc ID 380490.1 (EBS 12.1)

4. Strengthen WAF and SSRF Protections

If you use a Web Application Firewall (WAF):

  • Ensure Server-Side Request Forgery (SSRF) protection rules are active and tested.

  • Block or rate-limit suspicious requests targeting Configurator URLs.

5. Temporary Mitigation (if patching is delayed)

If immediate patching isn’t possible, take the following steps to reduce exposure:

  • Disable Oracle Configurator using Allowed Resources.

  • Block Configurator endpoints via WAF or network firewall.

  • Restrict external access to trusted internal subnets only.

  • Enable OHS URL firewall and verify that unnecessary routes are filtered.

  • Monitor logs and WAF alerts for unusual traffic or Configurator access attempts.

6. Final Recommendation

CVE-2025-61884 highlights a recurring theme — unpatched and unused components create unnecessary exposure.

To stay secure:

  • Patch first — apply the July 2025 CPU.

  • Disable unused components like Oracle Configurator.

  • Harden configurations with URL firewalls and Allowed Resources.

  • Continuously monitor for anomalies and ensure EBS remains compliant.
