CVE-2025-30735: PeopleSoft Auth Bypass Vulnerability

CVE-2025-30735 Overview

CVE-2025-30735 is an improper access control vulnerability affecting Oracle PeopleSoft Enterprise CC Common Application Objects, specifically within the Page and Field Configuration component. This security flaw allows a low-privileged attacker with network access via HTTP to compromise the affected system. The vulnerability enables unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to sensitive information stored within the PeopleSoft application.

Critical Impact

Successful exploitation grants attackers the ability to manipulate and access critical data within PeopleSoft Enterprise CC Common Application Objects, potentially compromising business-critical information and system integrity.

Affected Products

• Oracle PeopleSoft Enterprise CC Common Application Objects version 9.2

Technical Details for CVE-2025-30735

Vulnerability Analysis

This vulnerability is classified under CWE-284 (Improper Access Control), indicating that the Page and Field Configuration component fails to properly restrict access to protected resources. The flaw is easily exploitable over the network, requiring only low-level privileges and no user interaction. An attacker who has authenticated to the PeopleSoft system with minimal privileges can leverage this vulnerability to bypass intended access restrictions.

The exploitation results in dual impacts to confidentiality and integrity. Attackers can gain unauthorized read access to critical data throughout the PeopleSoft Enterprise CC Common Application Objects system, as well as the ability to create, modify, or delete sensitive records. This combination makes the vulnerability particularly dangerous for organizations relying on PeopleSoft for managing critical business processes and sensitive data.

Root Cause

The vulnerability stems from improper access control implementation within the Page and Field Configuration component. The application fails to adequately verify user permissions before granting access to sensitive operations and data. This allows authenticated users with low-level privileges to perform actions that should be restricted to higher-privileged roles or administrators.

Attack Vector

The attack is conducted remotely over the network via HTTP requests to the vulnerable PeopleSoft application. An attacker must first obtain valid credentials with low-level privileges, which could be achieved through credential theft, social engineering, or exploitation of another vulnerability. Once authenticated, the attacker can craft requests that exploit the access control weakness to access or modify data beyond their authorized scope.

The vulnerability does not require any user interaction to exploit, making it particularly dangerous in environments where PeopleSoft applications are exposed to broader network segments or the internet. For detailed technical information, refer to the Oracle Security Alert April 2025.

Detection Methods for CVE-2025-30735

Indicators of Compromise

• Unusual data access patterns from low-privileged user accounts accessing Page and Field Configuration components
• Audit log entries showing unexpected create, update, or delete operations on critical data by non-administrative users
• HTTP requests to PeopleSoft endpoints containing parameters or paths associated with Page and Field Configuration that originate from unexpected user sessions
• Anomalous query patterns in PeopleSoft database logs indicating bulk data retrieval or modification operations

Detection Strategies

• Enable comprehensive auditing within Oracle PeopleSoft to track all data access and modification events in the Page and Field Configuration component
• Implement application-level logging to capture HTTP requests and correlate them with authenticated user sessions
• Deploy network monitoring solutions to detect suspicious traffic patterns targeting PeopleSoft application servers
• Configure SIEM rules to alert on privilege escalation indicators or unusual data access patterns from low-privileged accounts

Monitoring Recommendations

• Review PeopleSoft security audit logs regularly for unauthorized access attempts to Page and Field Configuration features
• Monitor database transaction logs for bulk data operations or suspicious modification patterns
• Implement user behavior analytics to identify deviations from normal access patterns
• Track failed and successful authentication events to identify potential credential compromise

How to Mitigate CVE-2025-30735

Immediate Actions Required

• Apply the Oracle Critical Patch Update (CPU) from April 2025 immediately to all affected PeopleSoft Enterprise CC Common Application Objects version 9.2 installations
• Review and audit user permissions within the Page and Field Configuration component to ensure principle of least privilege
• Restrict network access to PeopleSoft applications to trusted networks and authorized users only
• Enable enhanced auditing and logging to detect potential exploitation attempts

Patch Information

Oracle has released a security patch addressing this vulnerability as part of the April 2025 Critical Patch Update. Organizations should obtain and apply the patch from the Oracle Security Alert April 2025. It is strongly recommended to test the patch in a non-production environment before deploying to production systems. Ensure proper backup procedures are followed before applying any patches.

Workarounds

• Implement network segmentation to restrict access to PeopleSoft servers from untrusted network segments
• Review and tighten PeopleSoft role-based access controls to minimize the number of users with access to Page and Field Configuration
• Deploy a web application firewall (WAF) to monitor and filter suspicious HTTP requests to the PeopleSoft application
• Consider implementing additional authentication factors for accessing sensitive PeopleSoft components until the patch can be applied
