Oracle E-Business Suite Exposed: Unauthenticated Access via CVE-2025-30708

Introduction

Oracle's E-Business Suite, a cornerstone of enterprise resource planning, faces a critical security threat. CVE-2025-30708 exposes sensitive user management data to unauthenticated attackers, potentially compromising extensive organizational information.

Affected Systems and Versions

• Oracle E-Business Suite: Versions 12.2.4 through 12.2.14
• Component: Oracle User Management (Search and Register Users)
• Configuration: All instances accessible via HTTP without additional authentication layers

Technical Information

The vulnerability arises from inadequate authorization checks within the 'Search and Register Users' functionality of Oracle User Management. Attackers can exploit this flaw by crafting specific HTTP requests, bypassing authentication entirely to access sensitive data stored within the system. This includes encrypted passwords, API keys, and user role assignments, significantly impacting confidentiality.

Attack Vector

• Network-based (AV:N): Exploitation occurs remotely over HTTP/HTTPS.
• Low Complexity (AC:L): No special conditions or complex interactions required.
• No Privileges Required (PR:N): Attackers do not need prior authentication.

Patch Information

Oracle has addressed this vulnerability in its April 2025 Critical Patch Update. Organizations must upgrade Oracle E-Business Suite to the latest patched version provided in this update. The patch specifically rectifies authorization logic within the vulnerable component.

• Patch Link: Oracle April 2025 CPU
• Recommended Action: Immediate application of the provided patch.

Alternative Mitigations

• Restrict external HTTP/HTTPS access to Oracle E-Business Suite.
• Implement TLS client authentication for administrative interfaces.
• Audit and monitor database privileges and access logs.

Detection Methods

• Monitor HTTP logs for unusual access patterns targeting the /OA_HTML/umxui endpoint.
• Audit database access logs for unauthorized queries against sensitive UMX tables.

Vendor Security History

Oracle's E-Business Suite has historically faced similar vulnerabilities, notably CVE-2022-21587, which saw active exploitation. Oracle typically addresses such vulnerabilities in quarterly CPUs, though the complexity of their software can complicate timely remediation.
