CVE-2026-62601: Oracle Sales Auth Bypass Vulnerability

CVE-2026-62601 Overview

CVE-2026-62601 is a high-severity vulnerability in the Oracle Sales 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 via HTTP can exploit this issue without user interaction. Successful exploitation leads to unauthorized access to critical Oracle Sales data and unauthorized update, insert, or delete operations against a subset of that data. Oracle addressed the issue in its August 2026 security alert cycle.

Critical Impact
An authenticated remote attacker with low privileges can read all Oracle Sales accessible data and modify a subset of it over HTTP.

Affected Products

Oracle E-Business Suite — Oracle Sales product
Component: Internal Operations
Supported versions 12.2.3 through 12.2.15

Technical Details for CVE-2026-62601

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of the Oracle Sales product within Oracle E-Business Suite. The flaw is remotely exploitable over HTTP and requires the attacker to hold a low-privileged application account. No user interaction is required to trigger the condition. Oracle classifies the impact as high on confidentiality and low on integrity, with no availability impact. In practical terms, an authenticated attacker can read all data accessible to the Oracle Sales module and perform limited unauthorized write operations against a subset of records.

Root Cause

Oracle has not published the technical root cause in the public advisory. The impact profile — high confidentiality and partial integrity impact reachable by a low-privileged user over HTTP — is consistent with a broken access control or authorization flaw in an Oracle Sales HTTP endpoint. Refer to the Oracle Security Alert for vendor-provided details.

Attack Vector

Exploitation requires network access to the Oracle E-Business Suite HTTP interface and valid credentials for a low-privileged account. The attacker sends crafted HTTP requests to the affected Oracle Sales Internal Operations endpoints. Because Oracle E-Business Suite is often exposed to internal networks and, in some deployments, to the internet through reverse proxies, the exposure surface is broad. No specialized tooling or user interaction is required.

No public proof-of-concept code is available for CVE-2026-62601 at the time of publication. See the Oracle Security Alert for authoritative technical guidance.

Detection Methods for CVE-2026-62601

Indicators of Compromise

Unexpected HTTP requests from low-privileged Oracle E-Business Suite accounts to Oracle Sales Internal Operations URLs.
Anomalous read volume against Oracle Sales tables from application service accounts.
Unexplained INSERT, UPDATE, or DELETE operations on Oracle Sales records outside normal business workflows.

Detection Strategies

Review Oracle E-Business Suite application audit logs for access to Internal Operations endpoints by accounts that should not require them.
Correlate HTTP access logs from the Oracle HTTP Server with database audit events on Oracle Sales schemas.
Baseline normal Oracle Sales query patterns per user role and alert on deviations in row counts or object scope.

Monitoring Recommendations

Enable Oracle Fine-Grained Auditing (FGA) on sensitive Oracle Sales tables to capture read and write access.
Forward Oracle E-Business Suite web and database audit logs to a centralized SIEM for retention and correlation.
Alert on repeated 4xx or 5xx responses from Oracle Sales Internal Operations endpoints, which may indicate exploitation attempts or reconnaissance.

How to Mitigate CVE-2026-62601

Immediate Actions Required

Apply the Oracle Critical Patch Update referenced in the August 2026 Security Alert as soon as change windows allow.
Inventory all Oracle E-Business Suite deployments and confirm which run affected versions 12.2.3 through 12.2.15.
Restrict network access to the Oracle E-Business Suite HTTP interface to trusted internal networks and VPN users.
Review and reduce the number of low-privileged application accounts with access to the Oracle Sales module.

Patch Information

Oracle released fixes for CVE-2026-62601 as part of its August 2026 security alert cycle. Administrators should download the applicable patch for their Oracle E-Business Suite 12.2.x release from My Oracle Support and follow the deployment steps documented in the Oracle Security Alert.

Workarounds

No vendor-supplied workaround has been published; patching is the primary remediation path.
Enforce least privilege on Oracle Sales responsibilities and remove unused role assignments while patching is scheduled.
Place a web application firewall in front of the Oracle E-Business Suite HTTP tier and restrict access to Oracle Sales Internal Operations URLs to specific user groups.

bash

# Example: restrict access to the Oracle E-Business Suite HTTP tier at the network edge
# Replace <trusted_subnet> and <ebs_host> with values for your environment
iptables -A INPUT -p tcp -s <trusted_subnet> --dport 8000 -d <ebs_host> -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -d <ebs_host> -j DROP
