CVE-2026-101815: Oracle E-Business Suite Assets DOS Vulnerability

CVE-2026-101815 Overview

CVE-2026-101815 is a high-severity vulnerability in the Assets 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 results in a complete denial of service through hangs or repeatable crashes of the Assets module. Attackers can also perform unauthorized updates, inserts, or deletes against a subset of Assets data, and read a limited subset of accessible data. The weakness is classified under CWE-284: Improper Access Control.

Critical Impact

Authenticated low-privileged attackers can crash Oracle E-Business Suite Assets and modify or read a subset of Assets data over the network.

Affected Products

• Oracle E-Business Suite Assets 12.2.3 through 12.2.15
• Component: Internal Operations
• Deployments exposing Oracle E-Business Suite HTTP interfaces to authenticated users

• October 2026 - Addressed in Oracle Critical Patch Update October 2026

Technical Details for CVE-2026-101815

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of the Oracle E-Business Suite Assets product. Oracle classifies the issue as easily exploitable, requiring only low privileges and network access over HTTP. No user interaction is needed, and the attack scope remains unchanged.

The primary impact is availability. Attackers can trigger a hang or a frequently repeatable crash, producing a complete denial of service for the Assets module. Secondary impacts include limited unauthorized write access and limited unauthorized read access to Assets data.

Root Cause

The weakness maps to CWE-284: Improper Access Control. The Assets product does not sufficiently enforce access restrictions on operations exposed through the Internal Operations component. Authenticated users with low privilege can reach code paths that should be restricted, enabling both data tampering and resource exhaustion conditions.

Attack Vector

Exploitation occurs remotely over HTTP against an exposed Oracle E-Business Suite instance. The attacker must hold a valid low-privileged account on the target system. Once authenticated, the attacker issues crafted requests to the Assets Internal Operations endpoints. Repeated requests can drive the module into a hang state or recurring crash, denying service to legitimate users while optionally altering a subset of accessible Assets records.

No public proof-of-concept has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog as of the latest NVD update. For technical specifics, consult the Oracle Critical Patch Update October 2026 advisory.

Detection Methods for CVE-2026-101815

Indicators of Compromise

• Repeated HTTP requests from a single authenticated session targeting Assets Internal Operations endpoints followed by service unavailability
• Unexpected insert, update, or delete operations against Assets tables by low-privileged accounts
• Oracle E-Business Suite application tier process restarts or thread hangs correlated with Assets request bursts

Detection Strategies

• Baseline normal request volume and user-role distribution for Assets URLs, then alert on deviations from low-privileged accounts
• Correlate Oracle E-Business Suite access logs with database audit trails to detect writes that bypass expected business workflows
• Monitor for repeated application errors or stack traces originating in the Assets Internal Operations module

Monitoring Recommendations

• Enable Oracle E-Business Suite application-tier audit logging and forward logs to a centralized analytics platform
• Enable database-level fine-grained auditing on Assets schemas to capture unauthorized DML activity
• Alert on Assets module crash events, restarts of Oracle HTTP Server workers, and sustained CPU or memory saturation on the application tier

How to Mitigate CVE-2026-101815

Immediate Actions Required

• Apply the fixes delivered in the Oracle Critical Patch Update October 2026 to all affected Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15
• Inventory all internet-exposed Oracle E-Business Suite environments and prioritize patching those first
• Review recent Assets activity by low-privileged accounts for signs of unauthorized data modification

Patch Information

Oracle addressed CVE-2026-101815 in the October 2026 Critical Patch Update. Administrators should download and apply the Assets-related patches referenced in the Oracle advisory. Verify that post-patch application versions reflect the fixed build and that the Assets module restarts cleanly after deployment.

Workarounds

• Restrict network access to Oracle E-Business Suite HTTP endpoints to trusted corporate networks and VPN users only
• Enforce least privilege on Oracle E-Business Suite user accounts, removing unnecessary access to the Assets product
• Place a web application firewall in front of Oracle E-Business Suite to rate-limit and inspect requests to Assets Internal Operations URLs
• Increase monitoring frequency on Assets services until the patch is applied
