CVE-2026-60793: Oracle TeleSales Auth Bypass Vulnerability

CVE-2026-60793 Overview

CVE-2026-60793 is a high-severity vulnerability in the Oracle TeleSales product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw 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 permits unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to all Oracle TeleSales accessible data. Oracle addressed the issue in the July 2026 Critical Patch Update.

Critical Impact
Authenticated network attackers can read and modify all data accessible to Oracle TeleSales, compromising confidentiality and integrity of business-critical CRM records.

Oracle E-Business Suite — Oracle TeleSales 12.2.3
Oracle E-Business Suite — Oracle TeleSales versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-60793

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle TeleSales, part of the Oracle E-Business Suite. Oracle TeleSales exposes HTTP endpoints used by internal sales and operations users to manage leads, opportunities, and customer records. The flaw allows an authenticated user with minimal privileges to bypass intended access controls and reach data and operations that should require higher authorization.

Because the attack vector is network-based over HTTP and requires no user interaction, an attacker only needs a valid low-privilege session — such as a standard TeleSales agent account — to exploit the issue. The impact spans both confidentiality and integrity: full read access to TeleSales data and the ability to create, modify, or delete records. Availability is not affected.

Oracle has not published the underlying CWE class or specific technical root cause. The characteristics — low complexity, low privileges, no user interaction, and broad data impact — are consistent with a broken access control or improper authorization flaw in an HTTP-facing servlet or business logic handler.

Root Cause

Oracle's advisory does not disclose the specific root cause. Based on the exploitation profile described in the CVE record, the defect stems from insufficient server-side authorization checks in the Internal Operations component, permitting a low-privileged authenticated user to invoke operations or query data outside the user's assigned role.

Attack Vector

Exploitation requires network reachability to the Oracle E-Business Suite HTTP layer and a valid authenticated session with low privileges. The attacker issues crafted HTTP requests to the Internal Operations endpoints of Oracle TeleSales to read, alter, or remove records. No social engineering or client-side interaction is required. Oracle-published exploitation details are unavailable, and no public proof-of-concept has been observed.

Detection Methods for CVE-2026-60793

Indicators of Compromise

Unexpected create, update, or delete operations against Oracle TeleSales records performed by accounts that do not routinely modify those objects.
Anomalous HTTP request volume to Oracle E-Business Suite endpoints associated with the TeleSales Internal Operations component.
Access to TeleSales data outside of a user's assigned territory, organization, or role scope.
Authenticated sessions from atypical source IPs or during off-hours that touch TeleSales URLs.

Detection Strategies

Enable Oracle E-Business Suite audit trail features for the TeleSales schema and review row-level changes against user role assignments.
Correlate application-tier access logs with database audit events to identify HTTP requests that resulted in bulk reads or writes by low-privileged users.
Baseline normal TeleSales HTTP request patterns per user role and alert on deviations in endpoint, verb, or record volume.

Monitoring Recommendations

Forward Oracle E-Business Suite application server logs, database audit logs, and web tier access logs to a centralized SIEM for correlation.
Alert on privilege-sensitive TeleSales URLs being accessed by accounts outside expected job functions.
Track failed authorization events and 4xx spikes that may indicate probing of Internal Operations endpoints.

How to Mitigate CVE-2026-60793

Immediate Actions Required

Apply the Oracle E-Business Suite fixes published in the Oracle Critical Patch Update July 2026 to all TeleSales instances running 12.2.3–12.2.15.
Inventory all internal and externally reachable Oracle E-Business Suite deployments and confirm patch status for the TeleSales product.
Rotate credentials for any low-privileged TeleSales accounts that could have been used for exploitation, and review recent activity in the TeleSales audit trail.

Patch Information

Oracle addressed CVE-2026-60793 as part of the July 2026 Critical Patch Update. Administrators must apply the patch bundle appropriate to their Oracle E-Business Suite 12.2.x release. Refer to the Oracle Critical Patch Update July 2026 advisory for patch identifiers, prerequisites, and installation guidance.

Workarounds

Restrict network access to the Oracle E-Business Suite HTTP layer using perimeter and internal firewall rules, allowing only trusted user networks.
Enforce least privilege on TeleSales responsibilities and remove unused or over-scoped role assignments until patching is complete.
Enable enhanced auditing on TeleSales tables and Internal Operations endpoints to increase visibility while remediation is in progress.
