CVE-2025-21541: Oracle Workflow Auth Bypass Vulnerability

CVE-2025-21541 Overview

CVE-2025-21541 is an authorization flaw in the Oracle Workflow product of Oracle E-Business Suite. The vulnerability resides in the Admin Screens and Grants UI component and affects supported versions 12.2.3 through 12.2.14. An authenticated attacker with low privileges can exploit the flaw over HTTP to gain unauthorized read, insert, update, or delete access to a subset of Oracle Workflow data. Oracle addressed the issue in the January 2025 Critical Patch Update. The weakness is classified under [CWE-281: Improper Preservation of Permissions].

Critical Impact
A low-privileged network attacker can modify and read a subset of Oracle Workflow data through the Admin Screens and Grants UI without user interaction.

Affected Products

Oracle E-Business Suite - Oracle Workflow 12.2.3
Oracle E-Business Suite - Oracle Workflow versions 12.2.4 through 12.2.13
Oracle E-Business Suite - Oracle Workflow 12.2.14

Technical Details for CVE-2025-21541

Vulnerability Analysis

The flaw resides in the Admin Screens and Grants UI of Oracle Workflow, a component that manages workflow definitions, notifications, and permission grants within Oracle E-Business Suite. The vulnerability allows a user who already holds a low-privileged account to reach administrative functionality that should be restricted to higher-privileged roles. Successful exploitation results in unauthorized insert, update, or delete operations against Oracle Workflow data, as well as unauthorized read access to a subset of that data.

Because Oracle Workflow underpins business processes such as approvals, notifications, and background job orchestration, tampering with its data can affect workflow routing decisions and audit records across E-Business Suite modules.

Root Cause

The root cause is improper preservation of permissions ([CWE-281]) within the Admin Screens and Grants UI. Authorization checks in this component do not adequately constrain what actions a low-privileged, authenticated user can perform. Oracle has not published a technical breakdown of the affected code paths; details are limited to the Oracle Critical Patch Update - January 2025.

Attack Vector

Exploitation requires network access over HTTP and a valid low-privileged account on the target Oracle E-Business Suite instance. No user interaction is required. The attacker interacts with the exposed Admin Screens and Grants UI endpoints of Oracle Workflow to invoke actions that alter or read Workflow-managed data. No public proof-of-concept or exploit tooling has been published, and CISA has not added this CVE to the Known Exploited Vulnerabilities catalog. The current EPSS probability is approximately 0.27%.

No verified exploit code is available. Refer to the Oracle Critical Patch Update advisory for technical guidance.

Detection Methods for CVE-2025-21541

Indicators of Compromise

Unexpected HTTP requests from low-privileged accounts to Oracle Workflow Admin Screens or Grants UI endpoints under the E-Business Suite web tier.
Unauthorized inserts, updates, or deletes in Oracle Workflow tables such as WF_ROLES, WF_USER_ROLES, or grant-related tables that cannot be tied to an approved change.
Anomalous session activity where standard business users trigger administrative Workflow actions.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and page access logs for access to Workflow administrative pages by non-administrative users.
Correlate database audit records on Workflow schema tables with the invoking application user and responsibility.
Baseline normal Workflow administrative usage and alert on deviations, such as new user-role grants issued outside change windows.

Monitoring Recommendations

Forward E-Business Suite application and Apache access logs to a centralized SIEM for retention and correlation.
Monitor for HTTP 200 responses to Workflow Admin URLs originating from accounts without administrative responsibilities.
Alert on privilege or grant changes within Oracle Workflow that occur outside approved maintenance windows.

How to Mitigate CVE-2025-21541

Immediate Actions Required

Apply the January 2025 Critical Patch Update for Oracle E-Business Suite to all Oracle Workflow deployments running versions 12.2.3 through 12.2.14.
Inventory all E-Business Suite environments, including non-production, and confirm patch status for the Workflow component.
Review recent Workflow grant and role changes for signs of unauthorized activity prior to patching.

Patch Information

Oracle addressed CVE-2025-21541 in the Oracle Critical Patch Update - January 2025. Administrators should follow Oracle's E-Business Suite patch application procedures and validate that the Workflow component's patch level reflects the January 2025 CPU after deployment.

Workarounds

Restrict network access to E-Business Suite administrative URLs, including Workflow Admin Screens and Grants UI, using reverse proxy or WAF rules until patching is complete.
Reduce the number of accounts assigned Workflow-related responsibilities and remove unused or dormant application users.
Enforce multi-factor authentication and strong password policies on E-Business Suite accounts to raise the cost of obtaining the low-privileged access required for exploitation.
