CVE-2026-70696: Oracle Payments Information Disclosure

CVE-2026-70696 Overview

CVE-2026-70696 is an information disclosure vulnerability in the File Transmission component of Oracle Payments, part of the Oracle E-Business Suite. The flaw allows an unauthenticated remote attacker with TCP network access to compromise the confidentiality of data managed by Oracle Payments. Successful exploitation grants unauthorized access to critical data or complete access to all Oracle Payments accessible data. Oracle rates the vulnerability as easily exploitable, requiring no user interaction and no privileges. Supported versions 12.2.3 through 12.2.15 are affected.

Critical Impact
An unauthenticated network-based attacker can access sensitive payment data stored or transmitted by Oracle Payments without authentication or user interaction.

Affected Products

Oracle E-Business Suite — Oracle Payments 12.2.3
Oracle E-Business Suite — Oracle Payments versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Payments 12.2.15

Technical Details for CVE-2026-70696

Vulnerability Analysis

The vulnerability resides in the File Transmission component of Oracle Payments. Oracle Payments handles disbursement and funds capture across Oracle E-Business Suite, and the File Transmission subsystem exchanges payment files with financial institutions. The flaw permits an attacker to reach the component over TCP without authenticating and to retrieve sensitive data.

Oracle classifies the issue as impacting confidentiality only. Integrity and availability of the target system remain unaffected. The scope of exposed data ranges from critical records to the full set of information accessible to Oracle Payments, which typically includes payment instructions, bank account details, and settlement files.

The EPSS model estimates a 0.303% probability of exploitation within 30 days. Oracle has not published detailed root-cause information beyond the advisory, and no public proof-of-concept has been observed at the time of publication.

Root Cause

Oracle's advisory does not disclose the underlying defect class. Based on the CVSS metrics and the component involved, the weakness is a missing or improperly enforced authentication or access control check on a File Transmission network endpoint. The endpoint appears to expose payment-related data to unauthenticated TCP clients.

Attack Vector

An attacker with network reachability to the Oracle Payments File Transmission service sends crafted TCP requests to the exposed endpoint. Because no credentials or user interaction are required, exploitation reduces to identifying an exposed instance and issuing requests that return payment data. Refer to the Oracle Security Alert for vendor-specific technical detail.

Detection Methods for CVE-2026-70696

Indicators of Compromise

Unexpected inbound TCP connections to Oracle Payments File Transmission listeners from untrusted networks or unrecognized source addresses.
Anomalous outbound transfers of payment files, XML payloads, or settlement records from Oracle E-Business Suite hosts.
Access log entries showing File Transmission requests without corresponding authenticated user sessions.

Detection Strategies

Inventory Oracle E-Business Suite deployments and confirm running versions between 12.2.3 and 12.2.15 to scope exposure.
Correlate application server logs, database audit logs, and network flow data to identify unauthenticated requests reaching Oracle Payments endpoints.
Baseline normal File Transmission volumes and alert on deviations in request rate, size, or peer address.

Monitoring Recommendations

Enable verbose logging on Oracle Payments and forward logs to a centralized analytics platform for retention and query.
Monitor perimeter and internal firewalls for TCP traffic destined to Oracle Payments ports originating from non-approved networks.
Alert on any changes to Oracle Payments configuration files, iBy schema tables, or File Transmission profile settings.

How to Mitigate CVE-2026-70696

Immediate Actions Required

Apply the fixes referenced in the Oracle Critical Patch Update Advisory published August 2026 to all affected Oracle Payments installations.
Restrict TCP access to Oracle Payments File Transmission endpoints to trusted management and integration networks only.
Audit recent File Transmission activity for evidence of unauthorized data retrieval since the affected versions were deployed.

Patch Information

Oracle has released fixes through its August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for the specific patch identifiers that apply to versions 12.2.3 through 12.2.15 and stage them in non-production environments before production deployment.

Workarounds

Place Oracle Payments servers behind a reverse proxy or web application firewall that enforces authentication and IP allow-listing until patches are applied.
Disable or firewall the File Transmission listener where the component is not required for business operations.
Rotate credentials, API keys, and payment integration secrets that may have been exposed through the File Transmission channel.

bash

# Example: restrict inbound TCP access to the Oracle Payments host
# Replace <mgmt-cidr> and <ebs-port> with environment-specific values
iptables -A INPUT -p tcp -s <mgmt-cidr> --dport <ebs-port> -j ACCEPT
iptables -A INPUT -p tcp --dport <ebs-port> -j DROP
