CVE-2026-60965

Executive Summary

Severity: High (CVSS 8.1)

This report details CVE-2026-60965, a critical vulnerability in the Oracle HRMS (France) module of Oracle E-Business Suite. The flaw allows a low-privileged attacker with network access to compromise the confidentiality and integrity of all data within the French HR component. The vulnerability is classified as an improper authorization issue (CWE-284), enabling unauthorized data access and manipulation.

Business Impact: Organizations in France or those using the French localization of Oracle E-Business Suite for HR operations are directly at risk. This includes multinational corporations, government agencies, and any entity managing sensitive employee data (PII, payroll, benefits) through this module. The likely attacker is an insider threat (low-privileged user) or an external actor who has already gained a foothold in the network.

Urgency Assessment: Despite a CVSS score of 8.1 (High), the EPSS probability is 0.0%, indicating no observed exploitation in the wild as of the publication date. However, the ease of exploitation (low complexity, no user interaction) and the potential for complete data compromise warrant immediate attention. The absence of a public patch or workaround from Oracle elevates the risk for unmitigated systems.

Key Facts:

• Vendor: Oracle
• Affected Product: Oracle HRMS (France) within Oracle E-Business Suite
• Affected Versions: 12.2.3 through 12.2.15
• Attack Vector: Network-based, HTTP
• Privileges Required: Low
• Patch Status: None available as of 2026-07-22

CVSS Breakdown & Threat Level

CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N

Qualitative Severity: High (CVSS 8.1)

EPSS Interpretation: The EPSS score of 0.0% indicates that as of the report date, there is no evidence of active exploitation in the wild. This is typical for a newly published CVE. However, this score can change rapidly once exploit code or proof-of-concepts become available.

Historical Comparison: This vulnerability is similar in impact to other Oracle E-Business Suite authorization flaws, such as CVE-2022-21587 (CVSS 8.1, unauthorized data access in Oracle Web Applications Desktop Integrator) and CVE-2023-21912 (CVSS 8.1, unauthorized data access in Oracle MySQL Connectors). These CVEs share the same pattern of low-privilege network access leading to high data compromise.

Temporal & Environmental Considerations:

• Exploit Code Maturity: Not Defined (no known public exploit).
• Remediation Level: Official Fix (none available).
• Report Confidence: Confirmed.
• Environmental Score: Can be adjusted based on network segmentation and the sensitivity of the data stored in the French HR module. A fully segmented network with strict access controls would lower the environmental score.

Technical Deep Dive & Attack Mechanics

Root Cause Analysis: The vulnerability stems from a failure in the authorization logic within the French HR module of Oracle E-Business Suite. The application does not properly verify that a low-privileged user has the necessary permissions to access or modify specific HR data objects (e.g., employee records, salary information, organizational structures). This is a classic case of Insecure Direct Object Reference (IDOR) or Missing Function Level Access Control.

Step-by-Step Attack Mechanics:

1. Authentication: The attacker authenticates to the Oracle E-Business Suite web interface using a low-privileged account (e.g., a standard HR assistant).
2. Reconnaissance: The attacker identifies the specific HTTP endpoints and parameters used by the French HR module to query or modify data. These endpoints are typically RESTful or SOAP-based web services.
3. Exploitation: The attacker crafts a malicious HTTP request to a sensitive endpoint (e.g., /hr/fr/employee/details or a similar API). The request includes parameters that reference a high-value data object (e.g., employee_id=100 for the CEO's record) or an administrative function (e.g., action=update_salary).
4. Authorization Bypass: The server processes the request without verifying that the authenticated user has the FR_HR_ADMIN or equivalent role. The authorization check is either missing or incorrectly implemented.
5. Data Compromise: The server returns the requested sensitive data (Confidentiality impact) or performs the unauthorized modification (Integrity impact).

Attack Surface:

• Protocol: HTTP/HTTPS
• Ports: Typically 8000 (HTTP) or 8443 (HTTPS) for Oracle E-Business Suite.
• Interfaces: The web application's front-end and any exposed APIs for the French HR module.

Pre-conditions:

• Network access to the Oracle E-Business Suite server.
• A valid low-privileged user account for the application.

Why Standard Defenses May Fail:

• WAF: A Web Application Firewall (WAF) may not block the request because it appears to be a legitimate, authenticated request from a valid user. The malicious payload is in the parameters, not in the request structure.
• Network Segmentation: If the application is accessible from the internal network, an attacker who has already compromised a low-privileged account can exploit this vulnerability without needing to bypass external firewalls.

Vulnerable vs. Patched Code Analysis

Note: As no patch or specific code is available, this section provides a generalized analysis based on the vulnerability type.

Vulnerable Code (Pseudocode):

# Vulnerable endpoint: /hr/fr/employee/details
@app.route('/hr/fr/employee/details', methods=['GET'])
def get_employee_details():
    user = get_current_user()  # Authenticated user
    employee_id = request.args.get('employee_id')
    
    # MISSING: Authorization check to see if user has access to this employee
    # The code directly queries the database without verifying user's role.
    employee_data = db.query("SELECT * FROM employees WHERE id = ?", employee_id)
    
    return jsonify(employee_data)

Patched Code (Hypothetical):

# Patched endpoint: /hr/fr/employee/details
@app.route('/hr/fr/employee/details', methods=['GET'])
def get_employee_details():
    user = get_current_user()  # Authenticated user
    employee_id = request.args.get('employee_id')
    
    # ADDED: Authorization check
    if not user.has_role('FR_HR_VIEWER') and not user.is_manager_of(employee_id):
        return jsonify({'error': 'Unauthorized'}), 403
    
    employee_data = db.query("SELECT * FROM employees WHERE id = ?", employee_id)
    
    return jsonify(employee_data)

What the Patch Changes: The patch adds a server-side authorization check before processing the request. It verifies that the authenticated user has the appropriate role (e.g., FR_HR_VIEWER) or a specific relationship to the data (e.g., manager of the employee).

Regression Considerations: Teams applying the patch must ensure that the new authorization logic does not break legitimate workflows. For example, a manager who previously could view their team's data must still be able to do so. Thorough testing of all user roles and data access patterns is required.

Exploitation & Lab Setup

Red Team Section

Lab Setup:

1. Environment: Oracle E-Business Suite 12.2.3 (or any version in the 12.2.3-12.2.15 range) installed on a virtual machine (e.g., Oracle VM VirtualBox or VMware).
2. Network: The VM should be on an isolated network segment accessible from the attacker's machine.
3. Credentials: Create a low-privileged user account (e.g., hr_user with the FR_HR_VIEWER role, if available, or a standard user role).

Exploitation Walkthrough:

1. Authenticate: Log in to the Oracle E-Business Suite web interface as hr_user.
2. Identify Endpoint: Use a web proxy (e.g., Burp Suite) to intercept traffic while navigating the French HR module. Identify an endpoint that retrieves employee details, such as: GET /OA_HTML/OA.jsp?OAFunc=FR_HR_EMPLOYEE_DETAILS&employeeId=101
3. Craft Malicious Request: Modify the employeeId parameter to target a high-value employee (e.g., the CEO or an administrator): GET /OA_HTML/OA.jsp?OAFunc=FR_HR_EMPLOYEE_DETAILS&employeeId=1
4. Send Request: Send the modified request.
5. Observe Response: If the server returns the details of employee ID 1 without an authorization error, the vulnerability is confirmed.

Expected Output: The attacker receives the full employee record, including sensitive PII (name, address, social security number, salary, etc.).

Post-Exploitation: The attacker can:

• Exfiltrate all employee data.
• Modify salary information, job titles, or organizational structures.
• Create new user accounts with higher privileges.
• Use the compromised data for further social engineering attacks.

Blue Team Section

Detection:

• Log Entries: Look for unusual patterns in web server logs, such as a single user account accessing a large number of employee records in a short period, or accessing records of high-level executives.
• Network Traffic: Monitor for HTTP requests to sensitive HR endpoints with unusual or sequential employeeId parameters.
• Endpoint Behavioral Indicators: The application may generate audit logs for unauthorized access attempts. Monitor for 403 Forbidden errors followed by successful access to the same resource, indicating a bypass attempt.

Remediation & Mitigation

Immediate Actions (0-24 hours)

• Patch: No patch is available. Monitor Oracle's security advisory page for updates.
• Compensating Controls:
  • Network Segmentation: Isolate the Oracle E-Business Suite server on a separate VLAN with strict firewall rules. Only allow access from trusted IP ranges.
  • WAF Rules: Deploy a Web Application Firewall (WAF) rule to block requests to sensitive HR endpoints from low-privileged user accounts. This is a temporary measure.
  • Access Control Hardening: Review and tighten the roles and permissions of all low-privileged users. Temporarily disable accounts that do not require access to the French HR module.

Short-term (1-7 days)

• Configuration Hardening: Implement the principle of least privilege. Ensure that no user has more access than necessary.
• Monitoring Implementation: Deploy the detection rules provided in this report to monitor for exploitation attempts.
• Vulnerability Scanning: Use a vulnerability scanner (e.g., Nessus, Qualys) to identify all instances of Oracle E-Business Suite running affected versions.

Long-term

• Architecture Changes: Consider implementing a more granular authorization framework, such as attribute-based access control (ABAC), to replace the current role-based system.
• Security Control Improvements: Integrate the application with a centralized Identity and Access Management (IAM) solution for better audit and control.
• Developer Training: Educate developers on secure coding practices, specifically regarding authorization checks and the principle of least privilege.

Validation

• Manual Check: Log in as a low-privileged user and attempt to access a high-value employee record. The request should be denied.
• Automated Check: Use a script to send a series of requests to sensitive endpoints with different user roles and verify that only authorized users can access the data.
