CVE-2026-60759: Oracle E-Business Auth Bypass Vulnerability

CVE-2026-60759 Overview

CVE-2026-60759 is an access control vulnerability [CWE-284] in the Oracle Internet Procurement Connector product of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. An unauthenticated attacker with network access via HTTP can compromise the affected system, though successful exploitation requires overcoming high attack complexity. Successful attacks impact both confidentiality and integrity of data accessible through Oracle Internet Procurement Connector.

Critical Impact
Successful exploitation allows unauthenticated attackers to gain unauthorized read access and to create, modify, or delete critical data across all Oracle Internet Procurement Connector accessible data.

Affected Products

Oracle E-Business Suite - Oracle Internet Procurement Connector version 12.2.3
Oracle E-Business Suite - Oracle Internet Procurement Connector versions 12.2.4 through 12.2.14
Oracle E-Business Suite - Oracle Internet Procurement Connector version 12.2.15

Technical Details for CVE-2026-60759

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Internet Procurement Connector within Oracle E-Business Suite. An attacker interacts with the affected component over HTTP without any authentication or user interaction. The exploit path is difficult to execute, requiring specific conditions outside the attacker's direct control. Once achieved, the attacker gains broad read and write access to data managed by the Internet Procurement Connector.

The classification as [CWE-284] Improper Access Control indicates that the component fails to enforce sufficient authorization checks on network-reachable functionality. Oracle E-Business Suite deployments frequently sit at the core of procurement, financial, and supply-chain workflows, making unauthorized data modification particularly consequential.

Root Cause

Oracle has not published low-level technical details of the flaw. The CWE-284 designation indicates missing or incomplete access control enforcement on Internal Operations functionality that is reachable over HTTP without prior authentication. See the Oracle Security Alert for vendor-provided context.

Attack Vector

Exploitation is network-based over HTTP against the Oracle Internet Procurement Connector interface. No credentials and no user interaction are required. Because the component is intended for internal procurement operations, exposure of the Internet Procurement Connector endpoint to untrusted networks materially expands the attack surface. Verified public proof-of-concept code was not available at the time of publication.

Detection Methods for CVE-2026-60759

Indicators of Compromise

Unauthenticated HTTP requests targeting Oracle Internet Procurement Connector endpoints from unexpected source addresses.
Unexpected creation, deletion, or modification of records within Internet Procurement Connector tables and audit trails.
Access patterns to Internal Operations component URLs that do not correspond to legitimate internal procurement workflows.

Detection Strategies

Enable and review Oracle E-Business Suite application-tier access logs for anomalous requests to Internet Procurement Connector paths.
Correlate HTTP request logs against authenticated session activity to identify unauthenticated interactions with sensitive endpoints.
Baseline normal procurement data change rates and alert on deviations that could indicate unauthorized modification.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and web tier logs to a centralized SIEM for correlation and long-term retention.
Monitor perimeter and internal network devices for HTTP access to Oracle E-Business Suite from non-approved network segments.
Track privileged database operations on procurement schemas and generate alerts on unexpected write activity.

How to Mitigate CVE-2026-60759

Immediate Actions Required

Apply the security patch referenced in the Oracle Security Alert for affected Oracle E-Business Suite 12.2.3 through 12.2.15 deployments.
Restrict network access to Oracle Internet Procurement Connector endpoints so only trusted internal segments can reach the Internal Operations component.
Audit recent procurement data changes and Internet Procurement Connector logs for evidence of unauthorized activity.

Patch Information

Oracle addressed CVE-2026-60759 in the security update referenced in the August 2026 Oracle Security Alert. Administrators should consult the Oracle Security Alert for the specific patch identifiers and installation procedure that match their Oracle E-Business Suite 12.2.x release.

Workarounds

Place the Oracle E-Business Suite application tier behind a reverse proxy or web application firewall that blocks unauthenticated access to Internet Procurement Connector paths.
Enforce network segmentation so the Internet Procurement Connector is not reachable from the public internet or general user VLANs.
Disable or restrict the Internet Procurement Connector module in environments where it is not actively used until patching is complete.

bash

# Example: restrict Oracle E-Business Suite HTTP access at the network edge
# Replace 10.10.0.0/16 with your approved internal procurement subnet
iptables -A INPUT -p tcp --dport 8000 -s 10.10.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
