CVE-2026-62600: Oracle Sales Auth Bypass Vulnerability

CVE-2026-62600 Overview

CVE-2026-62600 affects the Oracle Sales product within Oracle E-Business Suite, specifically the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are vulnerable. An authenticated attacker with low privileges and network access via HTTP can compromise Oracle Sales. Successful exploitation grants unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all Oracle Sales accessible data.

Critical Impact
Low-privileged remote attackers can compromise the confidentiality and integrity of all Oracle Sales data, enabling unauthorized data disclosure and manipulation across the affected E-Business Suite deployment.

Affected Products

Oracle E-Business Suite — Oracle Sales 12.2.3 through 12.2.15
Component: Internal Operations
Deployments exposed to network-accessible HTTP endpoints

Technical Details for CVE-2026-62600

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Sales within Oracle E-Business Suite. An attacker holding a low-privileged account can send crafted HTTP requests to the affected endpoints to bypass access controls. The flaw enables unauthorized read, create, modify, and delete operations against data managed by Oracle Sales.

The impact is scoped to Oracle Sales but extends across all data accessible to the compromised context. Because Oracle Sales integrates with broader E-Business Suite modules, downstream business processes such as quoting, order capture, and customer records may be affected. The vulnerability does not require user interaction and can be triggered remotely.

Oracle rates this issue with high confidentiality and integrity impact and no availability impact. Detailed root-cause information has not been published by Oracle in the public advisory.

Root Cause

Oracle has not disclosed the specific weakness class in the public advisory. The behavior described in the advisory aligns with broken access control in the Internal Operations component, where authorization checks fail to constrain what a low-privileged authenticated user can read or modify through HTTP requests.

Attack Vector

Exploitation occurs over the network via HTTP against an Oracle E-Business Suite instance. The attacker must hold a valid low-privileged account on the target system. No user interaction is required. Because the vulnerable interface is HTTP-facing, any internet-exposed E-Business Suite deployment materially expands the attack surface.

No public proof-of-concept exploit code is available. Refer to the Oracle Security Alert for vendor-supplied technical guidance.

Detection Methods for CVE-2026-62600

Indicators of Compromise

Anomalous HTTP requests from low-privileged accounts targeting Oracle Sales Internal Operations URLs
Unexpected create, update, or delete operations in Oracle Sales tables outside normal business workflows
Session activity originating from atypical source IP ranges or user agents against /OA_HTML/ endpoints

Detection Strategies

Enable and forward Oracle E-Business Suite application and audit logs to a centralized analytics platform for correlation
Baseline normal Oracle Sales HTTP request patterns per user role and alert on deviations in request volume or endpoint access
Monitor database audit trails for unauthorized DML operations on Oracle Sales schema objects

Monitoring Recommendations

Track authentication events for low-privileged Oracle Sales accounts, focusing on off-hours activity
Alert on privilege boundary crossings where users access Internal Operations functionality outside their role
Retain HTTP access logs from front-end web tiers for retrospective investigation of suspicious sessions

How to Mitigate CVE-2026-62600

Immediate Actions Required

Apply the security patch referenced in the Oracle Security Alert as the primary remediation
Inventory all Oracle E-Business Suite instances running Oracle Sales versions 12.2.3 through 12.2.15
Restrict network access to E-Business Suite HTTP endpoints from untrusted networks until patches are applied
Review Oracle Sales account privileges and disable unused low-privilege accounts

Patch Information

Oracle has published remediation guidance in the Critical Security Patch Update advisory. Administrators should review the Oracle Security Alert for the applicable patch bundles, prerequisites, and installation procedures for supported Oracle E-Business Suite 12.2.x releases.

Workarounds

Place Oracle E-Business Suite behind a reverse proxy or web application firewall that restricts access to Internal Operations URLs
Enforce network segmentation so that only trusted internal ranges can reach the Oracle Sales HTTP interface
Increase database and application audit logging to shorten detection time until patches are deployed

bash

# Example: restrict access to Oracle E-Business Suite HTTP endpoints at the reverse proxy
# Replace TRUSTED_CIDR with the approved corporate range
location /OA_HTML/ {
    allow TRUSTED_CIDR;
    deny all;
    proxy_pass http://ebs-backend;
}
