CVE-2026-60782: Oracle Payments Auth Bypass Vulnerability

CVE-2026-60782 Overview

CVE-2026-60782 is a critical vulnerability in the Oracle Payments product of Oracle E-Business Suite, specifically within the File Transmission component. The flaw affects supported versions 12.2.3 through 12.2.15 and allows an unauthenticated attacker with network access via HTTP to compromise Oracle Payments. Successful exploitation results in a full takeover of the Oracle Payments instance, impacting confidentiality, integrity, and availability. The underlying weakness is classified as Missing Authentication for Critical Function [CWE-306].

Critical Impact
Unauthenticated remote attackers can take over Oracle Payments through the File Transmission component over HTTP with low attack complexity.

Technical Details for CVE-2026-60782

Vulnerability Analysis

The vulnerability resides in the File Transmission component of Oracle Payments, a module of Oracle E-Business Suite responsible for exchanging payment files with financial institutions. An unauthenticated attacker can reach the affected functionality over HTTP without any user interaction. Because the flaw permits full takeover of Oracle Payments, an attacker gains control over payment file processing, stored payment instructions, and downstream financial workflows. Compromise of this component exposes cardholder data, bank account details, and financial transaction records handled by the Oracle Payments subsystem.

Root Cause

The root cause is Missing Authentication for Critical Function [CWE-306]. The File Transmission component exposes functionality that should require authenticated, authorized access but instead accepts requests from unauthenticated network clients. The absence of an authentication check on this critical function allows remote adversaries to invoke sensitive operations directly.

Attack Vector

Exploitation requires only network access to the vulnerable Oracle E-Business Suite HTTP endpoint. No credentials, privileges, or user interaction are needed. An attacker sends crafted HTTP requests to the File Transmission interface to invoke functionality that should be restricted to authenticated users, achieving takeover of the Oracle Payments product. Internet-exposed Oracle E-Business Suite deployments are at the highest risk. Consult the Oracle Security Alert for vendor-specific technical details.

Detection Methods for CVE-2026-60782

Indicators of Compromise

Unauthenticated HTTP or HTTPS requests to Oracle Payments File Transmission endpoints originating from unexpected external IP addresses.
New or modified payment files, transmission configurations, or outbound bank instructions with no corresponding authenticated user session.
Unexpected outbound network connections from the Oracle E-Business Suite application tier to attacker-controlled hosts.
Application server or middleware logs showing anomalous request patterns targeting File Transmission servlets.

Detection Strategies

Review Oracle HTTP Server and WebLogic access logs for requests to File Transmission URLs that lack a valid authenticated session cookie.
Correlate database audit records for the Oracle Payments schema against authenticated user activity to spot unattributed changes.
Deploy web application firewall rules that alert on anonymous access to Oracle Payments endpoints.

Monitoring Recommendations

Forward Oracle E-Business Suite middleware, database audit, and network flow logs to a centralized SIEM for correlation.
Alert on spikes in HTTP traffic to /OA_HTML/ paths associated with the File Transmission servlet from external sources.
Monitor privileged database accounts used by Oracle Payments for unexpected query patterns or bulk data reads.

How to Mitigate CVE-2026-60782

Immediate Actions Required

Apply the fixes referenced in the Oracle Security Alert to all Oracle E-Business Suite instances running Oracle Payments versions 12.2.3 through 12.2.15.
Restrict network exposure of Oracle E-Business Suite HTTP endpoints, ensuring only trusted networks can reach the application tier.
Audit File Transmission activity and payment data for unauthorized changes prior to patching.

Patch Information

Oracle addressed CVE-2026-60782 as part of a security alert for Oracle E-Business Suite. Administrators should review the Oracle Security Alert and apply the specified patches for versions 12.2.3 through 12.2.15 of Oracle Payments. Verify patch installation through Oracle's OPatch inventory before returning the environment to production.

Workarounds

Place Oracle E-Business Suite behind a reverse proxy or WAF that enforces authentication before requests reach the File Transmission component.
Disable or block external access to File Transmission URLs at the load balancer or Oracle HTTP Server configuration until patches are applied.
Restrict source IP addresses permitted to reach Oracle Payments endpoints using network access control lists.
