CVE-2026-35241: PeopleSoft Student Records Auth Bypass

CVE-2026-35241 Overview

CVE-2026-35241 is a vulnerability affecting the PeopleSoft Enterprise CS Student Records product of Oracle PeopleSoft, specifically within the Research Tracking component. This improper access control flaw (CWE-284) allows a low-privileged attacker with network access via HTTP to compromise the affected system, potentially resulting in unauthorized access to critical data or complete access to all accessible PeopleSoft Enterprise CS Student Records data.

Critical Impact

Successful exploitation could result in unauthorized access to sensitive student records data, including research tracking information, compromising the confidentiality of educational institution data.

Affected Products

• Oracle PeopleSoft Enterprise CS Student Records version 9.2
• PeopleSoft Enterprise CS Student Records - Research Tracking component

Discovery Timeline

• April 21, 2026 - CVE-2026-35241 published to NVD

Technical Details for CVE-2026-35241

Vulnerability Analysis

This vulnerability stems from improper access control (CWE-284) in the Research Tracking component of Oracle PeopleSoft Enterprise CS Student Records. The flaw is easily exploitable by an attacker with low privileges who has network access via HTTP to the affected system. However, successful exploitation requires human interaction from a person other than the attacker, such as clicking a malicious link or visiting a compromised page.

The attack primarily impacts data confidentiality, with successful exploitation potentially granting attackers unauthorized access to critical data or complete access to all PeopleSoft Enterprise CS Student Records accessible data. The vulnerability does not allow for data modification or system availability disruption.

Root Cause

The root cause of this vulnerability is improper access control within the Research Tracking component. The application fails to properly validate user privileges and access permissions, allowing authenticated low-privileged users to access data they should not be authorized to view. This type of access control weakness can occur when authorization checks are missing, improperly implemented, or can be bypassed through specific request sequences.

Attack Vector

The attack vector for CVE-2026-35241 is network-based, utilizing HTTP requests to target the vulnerable Research Tracking component. An attacker would need:

1. Valid low-privileged credentials to the PeopleSoft Enterprise CS Student Records system
2. Network access to the target application via HTTP
3. A method to induce user interaction from another person (social engineering, phishing, etc.)

The exploitation path involves the attacker crafting specific HTTP requests that exploit the access control weakness. When combined with user interaction from another authenticated user, the attacker can leverage the vulnerability to access restricted student records data.

Detection Methods for CVE-2026-35241

Indicators of Compromise

• Unusual access patterns to the Research Tracking component from low-privileged accounts
• HTTP requests attempting to access student records data outside normal user authorization scope
• Anomalous data retrieval patterns indicating bulk extraction of student information
• Failed authorization attempts followed by successful data access using alternative request paths

Detection Strategies

• Monitor PeopleSoft application logs for unauthorized data access attempts in the Research Tracking module
• Implement web application firewall (WAF) rules to detect suspicious HTTP request patterns targeting student records endpoints
• Enable detailed audit logging for all Research Tracking component transactions
• Deploy user behavior analytics to identify privilege escalation attempts or unusual data access patterns

Monitoring Recommendations

• Configure alerts for access to sensitive student records from accounts that typically do not access this data
• Review PeopleSoft security event logs for authentication anomalies and access control violations
• Monitor network traffic for unusual HTTP request volumes to the Research Tracking component
• Implement database activity monitoring to track queries against student records tables

How to Mitigate CVE-2026-35241

Immediate Actions Required

• Review and apply the security patches provided in the Oracle April 2026 Security Alert
• Audit user access permissions within the Research Tracking component and remove unnecessary privileges
• Implement additional access controls and authentication requirements for sensitive student records data
• Enable comprehensive logging for the affected component to detect potential exploitation attempts

Patch Information

Oracle has addressed this vulnerability in the April 2026 Critical Patch Update. Organizations running PeopleSoft Enterprise CS Student Records version 9.2 should apply the relevant security patches immediately. The official patch and detailed remediation guidance are available in the Oracle April 2026 Security Alert.

Workarounds

• Implement network segmentation to restrict access to the PeopleSoft application from untrusted networks
• Deploy a web application firewall (WAF) with rules to filter suspicious HTTP requests targeting the Research Tracking component
• Enforce multi-factor authentication for all users accessing the PeopleSoft Enterprise CS Student Records system
• Limit user sessions and implement strict session timeout policies to reduce the attack window

# Example: Restrict access to PeopleSoft application server via firewall rules
# Allow only authorized internal networks to access the application
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
