CVE-2026-61107: Oracle E-Business Suite Privilege Escalation

CVE-2026-61107 Overview

CVE-2026-61107 is a high-severity vulnerability in the Oracle Applications DBA product of Oracle E-Business Suite, specifically within the Internal Operations component. Affected versions span 12.2.3 through 12.2.15. An authenticated attacker with high privileges and network access via HTTP can exploit the flaw to take over Oracle Applications DBA. Successful exploitation compromises confidentiality, integrity, and availability of the target system. Oracle addressed the vulnerability in the July 2026 Critical Patch Update.

Critical Impact
Successful exploitation results in complete takeover of Oracle Applications DBA, giving attackers full control over database administration functions within Oracle E-Business Suite.

Affected Products

Oracle E-Business Suite — Oracle Applications DBA, versions 12.2.3 through 12.2.15
Internal Operations component of Oracle Applications DBA
Deployments exposing Oracle E-Business Suite HTTP endpoints to authenticated users

Technical Details for CVE-2026-61107

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Applications DBA. Oracle characterizes the issue as easily exploitable by an attacker who already holds high privileges within Oracle E-Business Suite. The attacker leverages HTTP access to reach Internal Operations functionality and escalate to full takeover of Oracle Applications DBA.

Oracle Applications DBA governs core database administration tasks across the E-Business Suite. Compromise at this layer grants the attacker administrative reach over patching, cloning, and maintenance operations. This creates a persistent foothold that can affect all business modules dependent on the underlying database.

Oracle does not publish exploitation specifics for Critical Patch Update issues before customers patch. The advisory confirms full compromise of confidentiality, integrity, and availability of the Applications DBA component upon successful exploitation.

Root Cause

Oracle has not disclosed technical root-cause details. Based on the vector, the flaw resides in an authenticated HTTP-accessible interface of the Internal Operations component that fails to enforce sufficient authorization or input constraints against high-privileged callers.

Attack Vector

The attack requires network access over HTTP to the Oracle E-Business Suite application tier. The attacker must authenticate with high privileges. No user interaction is required, and the scope remains unchanged. Refer to the Oracle Security Alert July 2026 for vendor guidance.

No verified public exploit code exists for this vulnerability. Refer to vendor advisories for technical details.

Detection Methods for CVE-2026-61107

Indicators of Compromise

Unexpected administrative actions issued through Oracle Applications DBA Internal Operations endpoints by accounts that do not normally perform DBA tasks.
Anomalous HTTP requests targeting Internal Operations URLs from unusual source IPs or during off-hours.
New or modified database patch, clone, or maintenance jobs that lack a corresponding change ticket.

Detection Strategies

Enable and review Oracle E-Business Suite application-tier HTTP access logs for requests to Internal Operations components, correlating with authenticated user sessions.
Monitor privileged E-Business Suite accounts for behavioral deviations, such as new administrative operations or access from unfamiliar hosts.
Baseline normal DBA workflows and alert on Internal Operations activity outside of the expected change window.

Monitoring Recommendations

Forward E-Business Suite application-tier logs, database audit logs, and Oracle HTTP Server logs to a centralized SIEM for correlation.
Track failed and successful authentications to Applications DBA interfaces and alert on unusual privilege usage patterns.
Alert on modifications to FND_USER, responsibility grants, and any changes to Applications DBA schema objects.

How to Mitigate CVE-2026-61107

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite deployments running versions 12.2.3 through 12.2.15.
Inventory all Oracle Applications DBA accounts with high privileges and validate that each is still required.
Rotate credentials for high-privileged E-Business Suite accounts after patching to invalidate any pre-existing session or credential theft.

Patch Information

Oracle released the fix as part of the July 2026 Critical Patch Update. Administrators should follow the guidance and download links published in the Oracle Security Alert July 2026 and apply the update to the Oracle Applications DBA component.

Workarounds

Restrict network access to Oracle E-Business Suite application-tier HTTP endpoints so that only trusted administrative subnets can reach Internal Operations.
Enforce least privilege by reducing the number of accounts with high privileges in Oracle Applications DBA until the patch is deployed.
Enable multi-factor authentication in front of E-Business Suite administrative interfaces via a reverse proxy where supported.

bash

# Example: restrict access to Oracle E-Business Suite admin endpoints at the reverse proxy
# Adjust paths and allowed subnets to match your environment
location /OA_HTML/ {
    allow 10.10.20.0/24;   # DBA jump-host subnet
    deny  all;
    proxy_pass http://ebs-appserver:8000;
}
