CVE-2026-62445: Oracle Order Management Auth Bypass Flaw

CVE-2026-62445 Overview

CVE-2026-62445 is a high-severity access control weakness in the Product Diagnostic Tools component of Oracle Order Management, part of the Oracle E-Business Suite. Oracle E-Business Suite versions 12.2.4 through 12.2.15 are affected. A low-privileged attacker with network access over HTTP can exploit this flaw to compromise Oracle Order Management. Successful exploitation permits unauthorized creation, deletion, or modification of critical data, plus complete read access to Order Management data. The issue is categorized under [CWE-284] Improper Access Control.

Critical Impact
Authenticated network attackers can read, alter, or delete any data accessible to Oracle Order Management, undermining the confidentiality and integrity of order and customer records.

Affected Products

Oracle E-Business Suite — Oracle Order Management 12.2.4
Oracle E-Business Suite — Oracle Order Management 12.2.5 through 12.2.14

Technical Details for CVE-2026-62445

Vulnerability Analysis

CVE-2026-62445 resides in the Product Diagnostic Tools component of Oracle Order Management. The component fails to enforce access controls consistent with the privilege level of the calling user. As a result, an authenticated user with minimal application privileges can invoke diagnostic functionality that reaches sensitive Order Management data structures. The Oracle Critical Patch Update advisory classifies the flaw as network-exploitable over HTTP with low attack complexity. The EPSS forecast places the near-term exploitation probability in the lower percentile range, but the presence of Oracle E-Business Suite in high-value enterprise environments raises the practical risk.

Root Cause

The root cause is improper access control [CWE-284] in the Product Diagnostic Tools code path. Diagnostic endpoints intended for administrators or support personnel are reachable by lower-privileged authenticated users. The authorization layer does not adequately verify whether the requesting principal has the required responsibility or role before returning or mutating Order Management data.

Attack Vector

An attacker requires network reachability to the Oracle E-Business Suite HTTP interface and a valid low-privileged account. The attacker sends crafted HTTP requests to diagnostic endpoints exposed by the Order Management module. Because privilege checks are inadequate, the server executes the requested operation and returns or modifies data outside the attacker's authorization boundary. No user interaction is required, and the attack scope remains unchanged.

Oracle does not publish exploit code for Critical Patch Update issues. See the Oracle Security Alert July 2026 for the authoritative technical description and patch matrix.

Detection Methods for CVE-2026-62445

Indicators of Compromise

HTTP requests from low-privileged Oracle E-Business Suite accounts targeting Product Diagnostic Tools URLs under the Order Management module
Unexpected INSERT, UPDATE, or DELETE activity in Order Management tables initiated by user sessions without Order Management responsibilities
Access log entries showing diagnostic servlet invocations outside of scheduled maintenance windows

Detection Strategies

Correlate Oracle E-Business Suite FND_LOGIN and FND_UNSUCCESSFUL_LOGIN records with application server access logs to identify low-privilege users invoking diagnostic endpoints
Enable and review database-level auditing on Order Management schemas (ONT, OE) for data modifications lacking a corresponding front-end transaction
Alert on HTTP POST requests to /OA_HTML/ diagnostic paths from non-administrative session cookies

Monitoring Recommendations

Forward Oracle HTTP Server access logs and E-Business Suite concurrent manager logs to a centralized analytics platform for long-window correlation
Baseline normal usage of diagnostic tooling and alert on volumetric or off-hours deviations
Track privileged responsibility grants and revocations to detect staging activity that precedes exploitation

How to Mitigate CVE-2026-62445

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update for Oracle E-Business Suite to all instances running versions 12.2.4 through 12.2.15
Inventory user accounts with any Order Management responsibility and remove access that is not required for business function
Restrict network access to the E-Business Suite HTTP interface to trusted corporate networks and VPN ranges

Patch Information

Oracle addressed CVE-2026-62445 in the July 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert July 2026 for the specific patch identifiers applicable to their Oracle E-Business Suite 12.2.x release level and apply the fixes through Oracle's standard AutoPatch (adpatch/adop) workflow.

Workarounds

Disable or restrict access to Product Diagnostic Tools functionality where operationally feasible until patching completes
Place a web application firewall in front of the E-Business Suite HTTP tier and block requests to diagnostic URLs from non-administrative source addresses
Enforce network segmentation so that only administrative jump hosts can reach the Oracle E-Business Suite application tier
