CVE-2026-61028: Oracle Inventory Management DoS Vulnerability

CVE-2026-61028 Overview

CVE-2026-61028 is a local denial of service vulnerability in the Oracle Inventory Management product of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. A high-privileged attacker with logon access to the infrastructure hosting Oracle Inventory Management can trigger a partial denial of service condition. The vulnerability does not expose confidentiality or integrity impacts, only availability. Oracle addressed the issue in the Oracle July 2026 Security Alert.

Critical Impact
Successful exploitation results in a partial denial of service of Oracle Inventory Management, degrading availability of inventory operations within the E-Business Suite environment.

Technical Details for CVE-2026-61028

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Inventory Management, a module within Oracle E-Business Suite responsible for tracking and managing inventory transactions. Exploitation requires local logon access to the server infrastructure where Oracle Inventory Management executes. The attacker must already hold high privileges on the host, and the attack complexity is rated high because specific conditions must be met for the exploit to succeed. No user interaction is required, and the scope remains unchanged. The impact is limited to partial availability degradation of the Inventory Management service. The EPSS probability sits at 0.118%, reflecting a low likelihood of exploitation activity in the near term.

Root Cause

Oracle has not published a detailed technical root cause for this issue. Based on the CVSS profile, the flaw allows a privileged local user to trigger conditions that partially disrupt service processing within the Internal Operations component. Consult the Oracle July 2026 Security Alert for vendor-provided technical details.

Attack Vector

Exploitation requires the attacker to already possess high privileges on the host running Oracle Inventory Management. The attacker leverages that local access to interact with the Internal Operations component in a manner that partially exhausts or disrupts the service. Because the attack vector is local and complexity is high, remote or unauthenticated exploitation paths are not applicable.

No public proof-of-concept code is available for CVE-2026-61028. The vulnerability is described in prose only; see the vendor advisory for technical guidance.

Detection Methods for CVE-2026-61028

Indicators of Compromise

Unexpected slowdowns, hangs, or restarts of the Oracle Inventory Management service on affected E-Business Suite hosts.
Anomalous activity from privileged operating system accounts on the Oracle EBS application tier.
Repeated failed or malformed Internal Operations transactions in Oracle EBS application logs.

Detection Strategies

Monitor Oracle EBS application logs and concurrent manager logs for errors originating in the Internal Operations component of Inventory Management.
Baseline normal service response times and alert on sustained latency or availability regressions in Inventory Management.
Correlate local shell activity from privileged users with subsequent service degradation events.

Monitoring Recommendations

Enable and forward operating system audit logs from EBS application tier hosts to a centralized logging platform.
Track privileged logon events (oracle, applmgr, and equivalent service accounts) with alerting on off-hours access.
Instrument availability probes against Inventory Management endpoints to detect partial DoS conditions quickly.

How to Mitigate CVE-2026-61028

Immediate Actions Required

Apply the patches listed in the Oracle July 2026 Critical Patch Update to all Oracle E-Business Suite deployments running Inventory Management versions 12.2.3 through 12.2.15.
Inventory all EBS environments and confirm the patched version is deployed across production, test, and disaster recovery instances.
Restrict interactive logon on EBS application tier hosts to a minimum set of administrators.

Patch Information

Oracle released fixes for CVE-2026-61028 as part of the July 2026 Critical Patch Update. Administrators should download the applicable Oracle E-Business Suite 12.2 patch bundle from My Oracle Support and follow the standard EBS patching procedure, including preservation of customizations and post-patch validation of Inventory Management functionality. Refer to the Oracle July 2026 Security Alert for exact patch identifiers.

Workarounds

Enforce least privilege on the EBS application tier so that only trusted administrators hold logon rights to the host.
Require multi-factor authentication and jump-host mediation for any interactive session to Oracle EBS servers.
Segment the EBS application tier network so that lateral movement into the host is constrained pending patch deployment.
