CVE-2025-50062: PeopleSoft HCM Auth Bypass Vulnerability

CVE-2025-50062 Overview

CVE-2025-50062 is a privilege management vulnerability affecting the PeopleSoft Enterprise HCM Global Payroll Core product within Oracle PeopleSoft. The vulnerability exists in the Global Payroll for Core component and allows a low-privileged attacker with network access via HTTP to compromise the application. This security flaw enables unauthorized creation, deletion, or modification of critical data, as well as unauthorized access to sensitive payroll information.

Critical Impact

Successful exploitation allows attackers to gain unauthorized access to critical payroll data and modify or delete sensitive employee compensation records, potentially affecting organizational financial operations and data integrity.

Affected Products

• Oracle PeopleSoft Enterprise HCM Global Payroll Core version 9.2.51
• Oracle PeopleSoft Enterprise HCM Global Payroll Core version 9.2.52

Technical Details for CVE-2025-50062

Vulnerability Analysis

This vulnerability stems from improper privilege management (CWE-269) within the Global Payroll for Core component. The flaw allows authenticated users with low-level privileges to perform actions beyond their authorized scope, including accessing, modifying, or deleting critical payroll data they should not have permissions to manipulate.

The attack requires only network access via HTTP and does not require user interaction, making it particularly concerning for internet-facing PeopleSoft deployments. Once exploited, an attacker can compromise both the confidentiality and integrity of all data accessible through the Global Payroll Core module.

Root Cause

The vulnerability is classified under CWE-269 (Improper Privilege Management), indicating that the application fails to properly enforce access controls and privilege boundaries. The Global Payroll for Core component does not adequately verify that users have the appropriate authorization level before allowing sensitive operations on payroll data, enabling privilege escalation attacks.

Attack Vector

The attack vector is network-based, requiring the attacker to have low-privileged credentials and HTTP access to the PeopleSoft application. The exploitation path involves:

1. Authenticating to the PeopleSoft Enterprise HCM system with a low-privilege account
2. Leveraging the privilege management flaw to access the Global Payroll for Core component functions
3. Performing unauthorized operations on critical payroll data, including read access, modification, or deletion

The attack does not require any user interaction, making automated exploitation feasible once valid low-privilege credentials are obtained.

Detection Methods for CVE-2025-50062

Indicators of Compromise

• Unusual access patterns to Global Payroll Core component by low-privileged user accounts
• Unexpected modifications or deletions in payroll data tables not consistent with user role permissions
• Authentication events followed by access to payroll data outside normal business workflows
• Anomalous HTTP requests targeting Global Payroll for Core endpoints from unauthorized user contexts

Detection Strategies

• Implement audit logging for all access attempts to Global Payroll Core functionality and review for privilege misuse
• Monitor for low-privileged accounts attempting to access or modify critical payroll configuration data
• Deploy application-layer monitoring to detect unauthorized API calls to payroll data endpoints
• Configure SIEM alerts for unusual patterns of data access or modification in the HCM Global Payroll module

Monitoring Recommendations

• Enable detailed application logging within PeopleSoft for the Global Payroll for Core component
• Implement database activity monitoring to track SELECT, INSERT, UPDATE, and DELETE operations on payroll tables
• Configure real-time alerting for any critical data modifications performed by accounts below expected privilege levels
• Review PeopleSoft security audit reports regularly for access control violations

How to Mitigate CVE-2025-50062

Immediate Actions Required

• Apply the Oracle Critical Patch Update (CPU) for July 2025 to all affected PeopleSoft Enterprise HCM Global Payroll Core instances
• Audit current user permissions and ensure principle of least privilege is enforced for Global Payroll access
• Restrict network access to PeopleSoft instances using firewall rules and network segmentation
• Review recent access logs for any signs of unauthorized payroll data access or modification

Patch Information

Oracle has released a security patch addressing this vulnerability as part of the Oracle Critical Patch Update July 2025. Organizations running PeopleSoft Enterprise HCM Global Payroll Core versions 9.2.51 or 9.2.52 should apply this patch immediately.

Refer to the Oracle Security Alert July 2025 for detailed patching instructions and additional security recommendations from the vendor.

Workarounds

• Implement additional network-level access controls to limit HTTP access to the PeopleSoft application from trusted networks only
• Enable enhanced application logging and monitoring to detect potential exploitation attempts while awaiting patch deployment
• Review and restrict user roles with access to the Global Payroll for Core component to essential personnel only
• Consider temporarily disabling non-essential Global Payroll functionality until the patch can be applied

# Example: Restrict network access to PeopleSoft application servers
# Add firewall rules to limit access to trusted IP ranges only
iptables -A INPUT -p tcp --dport 80 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
