CVE-2026-61049: Oracle Production Scheduling Privilege Escalation

CVE-2026-61049 Overview

CVE-2026-61049 affects the Oracle Production Scheduling product within Oracle E-Business Suite, specifically the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are affected. An unauthenticated attacker with access to the adjacent physical communication segment can compromise Oracle Production Scheduling. Exploitation is difficult and requires human interaction from a user other than the attacker. Successful attacks result in complete takeover of Oracle Production Scheduling, impacting confidentiality, integrity, and availability.

Critical Impact
Successful exploitation leads to full takeover of Oracle Production Scheduling, compromising the confidentiality, integrity, and availability of scheduling operations across affected Oracle E-Business Suite deployments.

Affected Products

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

Technical Details for CVE-2026-61049

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Production Scheduling, part of Oracle E-Business Suite. Oracle classifies this issue as difficult to exploit because the attacker must be positioned on the adjacent physical network segment attached to the host running Production Scheduling. The attack requires no authentication but depends on user interaction from a person other than the attacker. Once triggered, the attack yields full takeover of the Production Scheduling application, granting the adversary control over scheduling data, workflows, and integrations with downstream manufacturing systems.

Root Cause

Oracle has not published a detailed technical root cause for CVE-2026-61049. The advisory attributes the flaw to the Internal Operations component of Production Scheduling and confirms that the required attacker position is on the local physical communication segment. See the Oracle Security Alert July 2026 for vendor-supplied details.

Attack Vector

The attack vector is Adjacent Network. An attacker on the same physical network segment as the Oracle Production Scheduling host initiates the exploit chain. Because the attack complexity is high, the attacker must satisfy specific timing, environmental, or protocol conditions. The scenario also requires an unwitting user to perform an action such as opening a scheduling artifact or interacting with a crafted resource. When the conditions align, the attacker gains complete control over the Production Scheduling instance.

No verified proof-of-concept code is publicly available. Refer to the vendor advisory for authoritative technical guidance.

Detection Methods for CVE-2026-61049

Indicators of Compromise

Unexpected modification of Production Scheduling data, plans, or job orders without corresponding user activity in audit logs.
New or altered administrative sessions originating from hosts on the same physical segment as the Production Scheduling server.
Anomalous outbound connections from the Oracle E-Business Suite application tier to non-approved internal endpoints.

Detection Strategies

Correlate Oracle E-Business Suite audit logs with network flow data to identify adjacent-network sessions initiating scheduling changes.
Monitor for user interaction patterns that immediately precede administrative changes in Production Scheduling, such as opening attachments or scheduling files from untrusted sources.
Baseline normal Production Scheduling API and interface traffic and alert on deviations from that baseline.

Monitoring Recommendations

Enable Oracle E-Business Suite auditing on the Production Scheduling module and forward events to a centralized SIEM.
Capture and retain network telemetry (NetFlow, packet metadata) for VLANs hosting Oracle E-Business Suite application servers.
Alert on privilege changes and configuration edits within Production Scheduling that occur outside of documented change windows.

How to Mitigate CVE-2026-61049

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update for Oracle E-Business Suite Production Scheduling as referenced in the Oracle Security Alert July 2026.
Inventory all Oracle Production Scheduling instances running versions 12.2.3 through 12.2.15 and prioritize patching for internet-adjacent and production environments.
Restrict physical and logical access to network segments that host Oracle E-Business Suite application servers.

Patch Information

Oracle addressed CVE-2026-61049 in the July 2026 Critical Patch Update. Administrators should review the Oracle Security Alert July 2026 advisory for patch identifiers applicable to Production Scheduling versions 12.2.3 through 12.2.15 and follow Oracle's documented application procedure for E-Business Suite.

Workarounds

Segment the network so that only authorized administrative hosts share a broadcast domain with Production Scheduling servers.
Enforce user awareness controls to reduce the likelihood that an operator performs the interaction required to trigger exploitation.
Disable or restrict unused Production Scheduling interfaces on the Internal Operations component until patching is complete.
