CVE-2026-60953: Oracle Billing Integrator Auth Bypass Bug

CVE-2026-60953 Overview

CVE-2026-60953 is a high-severity vulnerability in the Oracle Telecommunications Billing Integrator product, part of the Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit the issue without user interaction. Successful exploitation results in unauthorized creation, deletion, or modification of critical data, and full read access to all data accessible to Oracle Telecommunications Billing Integrator.

Critical Impact
Authenticated network attackers can compromise the confidentiality and integrity of all data accessible to Oracle Telecommunications Billing Integrator in affected Oracle E-Business Suite deployments.

Affected Products

Oracle Telecommunications Billing Integrator 12.2.3 through 12.2.15
Oracle E-Business Suite (Internal Operations component)
Deployments exposing HTTP endpoints of the affected component

Technical Details for CVE-2026-60953

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Telecommunications Billing Integrator. Oracle classifies the flaw as easily exploitable across the network by an authenticated attacker holding low privileges. Exploitation impacts confidentiality and integrity, while availability remains unaffected. The scope remains unchanged, meaning the impact is confined to the vulnerable component and the data it can access.

Because the attack is delivered over HTTP and requires no user interaction, the vulnerability suits use in automated attacks against exposed Oracle E-Business Suite deployments. An attacker who compromises any low-privileged account can leverage the flaw to read, modify, or delete billing integration data.

Root Cause

Oracle has not published root cause details in the public advisory. The Oracle Critical Patch Update advisory groups the issue under the Internal Operations component of the Telecommunications Billing Integrator module. Based on the impact profile (network HTTP, low privileges, confidentiality and integrity impact only), the flaw is consistent with a broken access control or input validation weakness in a web-facing operation.

Attack Vector

The attack vector is network-based over HTTP. An attacker requires an authenticated session with any low-privileged account on the target Oracle E-Business Suite instance. No user interaction is required. Once authenticated, the attacker sends crafted HTTP requests to the vulnerable Internal Operations endpoints to read or manipulate data outside the attacker's authorization boundary.

No public proof-of-concept code or exploit is available at the time of publication. The EPSS score is 0.392% (percentile 31.706), indicating a low near-term exploitation probability. Refer to the Oracle Security Alert July 2026 for vendor technical details.

Detection Methods for CVE-2026-60953

Indicators of Compromise

Unexpected HTTP requests to Oracle Telecommunications Billing Integrator Internal Operations endpoints from low-privileged user accounts.
Unusual create, update, or delete operations on billing integration records outside of scheduled batch windows.
Authentication anomalies such as low-privileged accounts issuing high-volume or off-hours requests to E-Business Suite modules.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and page access tracking for the Telecommunications Billing Integrator responsibility.
Correlate HTTP access logs from the Oracle HTTP Server tier with database audit records to identify unauthorized data reads or modifications.
Baseline normal traffic patterns to the Internal Operations component and alert on deviations in request volume, source IP, or user role.

Monitoring Recommendations

Forward Oracle HTTP Server, WebLogic, and database audit logs to a centralized SIEM for correlation.
Monitor low-privileged E-Business Suite accounts for privilege boundary violations and unexpected access to billing tables.
Alert on any changes to critical billing configuration or transactional data outside of approved change windows.

How to Mitigate CVE-2026-60953

Immediate Actions Required

Apply the fixes provided in the Oracle Security Alert July 2026 to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
Inventory Oracle Telecommunications Billing Integrator deployments and confirm patch status against the Oracle Critical Patch Update advisory.
Restrict network access to E-Business Suite HTTP endpoints so that only trusted internal networks can reach the Internal Operations component.
Review and reduce assignment of low-privileged responsibilities that can reach the Telecommunications Billing Integrator module.

Patch Information

Oracle addressed CVE-2026-60953 in the July 2026 Critical Patch Update. Administrators should download and apply the patch bundle for their supported Oracle E-Business Suite version. Full details, patch identifiers, and installation prerequisites are documented in the Oracle Security Alert July 2026.

Workarounds

Place the Oracle E-Business Suite HTTP tier behind a reverse proxy or web application firewall that restricts access to Internal Operations URLs.
Disable or revoke the Telecommunications Billing Integrator responsibility for accounts that do not require it until patches are applied.
Enforce network segmentation to prevent untrusted users from reaching the E-Business Suite application tier over HTTP.

bash

# Example: restrict access to the Telecommunications Billing Integrator context
# at the Oracle HTTP Server tier (httpd.conf / mod_authz)

    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
