CVE-2026-62524: Oracle HRMS SQL Injection Vulnerability

CVE-2026-62524 Overview

CVE-2026-62524 is a vulnerability in the Oracle HRMS (US) product of Oracle E-Business Suite, specifically within the US Payroll - General component. Supported versions 12.2.3 through 12.2.15 are affected. The flaw allows a low-privileged attacker with network access via HTTP to compromise Oracle HRMS (US). Successful exploitation can result in unauthorized update, insert, or delete access to a subset of Oracle HRMS (US) data, unauthorized read access to a subset of data, and a partial denial of service condition. The weakness is categorized under [CWE-200] (Exposure of Sensitive Information to an Unauthorized Actor).

Critical Impact
Authenticated attackers with low privileges can compromise payroll data integrity, read sensitive HR information, and disrupt Oracle HRMS (US) availability over the network.

Affected Products

Oracle E-Business Suite - Oracle HRMS (US) version 12.2.3
Oracle E-Business Suite - Oracle HRMS (US) versions 12.2.4 through 12.2.14
Oracle E-Business Suite - Oracle HRMS (US) version 12.2.15

Technical Details for CVE-2026-62524

Vulnerability Analysis

The vulnerability resides in the US Payroll - General component of Oracle HRMS (US), a module of Oracle E-Business Suite that manages employee compensation, tax withholding, and payroll processing. An authenticated attacker holding a low-privilege application account can send crafted HTTP requests to endpoints exposed by the HRMS (US) module and trigger the flaw without user interaction.

Successful exploitation produces three distinct outcomes. Attackers can perform unauthorized update, insert, or delete operations against a subset of HRMS (US) accessible data. They can also read a subset of HRMS data that should be restricted. Finally, they can cause a partial denial of service, degrading the availability of the HRMS (US) service. The mapping to [CWE-200] indicates the primary weakness class is improper exposure of sensitive information.

The Exploit Prediction Scoring System places this issue at a low probability of near-term exploitation. However, Oracle E-Business Suite deployments frequently expose HRMS modules to internal users across large enterprises, expanding the pool of low-privileged accounts that meet the exploitation prerequisites.

Root Cause

Oracle has not published root-cause internals. The CWE-200 mapping and the observed impact profile point to insufficient authorization checks or input validation in payroll-related HTTP handlers that permit a standard authenticated user to reach records and operations reserved for higher privilege tiers.

Attack Vector

The attack vector is network-based over HTTP. The attacker must hold valid low-privilege credentials to the Oracle E-Business Suite application. No user interaction is required, and attack complexity is low. Because the scope is unchanged, impact remains confined to the vulnerable HRMS (US) component.

No public proof-of-concept, exploit code, or CISA KEV listing exists for CVE-2026-62524 at the time of publication. Refer to the Oracle Security Alert July 2026 for vendor technical details.

Detection Methods for CVE-2026-62524

Indicators of Compromise

Unexpected HTTP requests from low-privileged Oracle E-Business Suite accounts to US Payroll servlets and JSP endpoints under the HRMS (US) module.
Unauthorized INSERT, UPDATE, or DELETE statements against payroll tables in the HR and PAY schemas originating from application user sessions.
Anomalous read access to payroll records by users whose HR responsibilities do not include US Payroll functions.
Elevated HTTP 5xx error rates or thread exhaustion on Oracle E-Business Suite middle tiers correlated with HRMS (US) traffic.

Detection Strategies

Audit Oracle E-Business Suite sign-on and responsibility usage logs for low-privileged accounts accessing US Payroll functions outside their assigned responsibilities.
Enable Oracle Database fine-grained auditing on PAY_* and HR_* tables to record DML activity by session user and application context.
Deploy web application firewall rules to inspect HTTP requests targeting HRMS (US) URLs and flag parameter tampering patterns.

Monitoring Recommendations

Correlate application-tier HTTP logs with database audit logs to identify request chains that produce unauthorized payroll data changes.
Alert on partial service degradation metrics such as spikes in servlet response time or connection pool saturation on HRMS (US) instances.
Review Oracle E-Business Suite FND_LOGIN and FND_UNSUCCESSFUL_LOGIN records for unusual authentication patterns preceding suspicious HRMS activity.

How to Mitigate CVE-2026-62524

Immediate Actions Required

Apply the fixes delivered in the Oracle Critical Patch Update July 2026 to all Oracle E-Business Suite environments running HRMS (US) versions 12.2.3 through 12.2.15.
Inventory user accounts with any responsibility that grants access to HRMS (US) and revoke unnecessary assignments.
Restrict network exposure of the Oracle E-Business Suite application tier to trusted corporate networks and VPN users.
Review recent payroll data changes for unauthorized modifications and validate against approved change tickets.

Patch Information

Oracle addressed CVE-2026-62524 in the July 2026 Critical Patch Update. Administrators should download and install the applicable Oracle E-Business Suite 12.2 patch bundle for the US Payroll component. Consult the Oracle Security Alert July 2026 advisory for patch identifiers, prerequisites, and post-installation steps.

Workarounds

Temporarily remove or restrict responsibilities granting access to US Payroll functions for accounts that do not require them until patches are applied.
Place the Oracle E-Business Suite HRMS (US) URLs behind a reverse proxy or WAF that enforces stricter authentication and inspects request parameters.
Increase database audit coverage on payroll schemas and route audit events to a centralized monitoring platform for review.
