CVE-2019-2929 in PeopleSoft Enterprise PeopleTools
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Portal). Supported versions that are affected are 8.56 and 8.57. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise PeopleSoft Enterprise PeopleTools. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PeopleTools, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PeopleSoft Enterprise PeopleTools accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise PeopleTools accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2019-2929 represents a critical security flaw within Oracle PeopleSoft Enterprise PeopleTools, specifically affecting the Portal component. This weakness exists in versions 8.56 and 8.57, making them susceptible to exploitation by unauthenticated attackers who can access the system through standard HTTP protocols. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this weakness, while the CVSS 3.0 base score of 6.1 reflects moderate severity with particular emphasis on confidentiality and integrity impacts.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the PeopleTools Portal component. Attackers can exploit this flaw to gain unauthorized access to sensitive data and system functionalities without requiring authentication credentials. The requirement for human interaction from a person other than the attacker suggests that social engineering or user manipulation may be necessary to initiate the attack vector, though the actual exploitation occurs through network-based HTTP access. This design flaw creates a pathway for unauthorized update, insert, or delete operations against PeopleSoft data, alongside unauthorized read access to specific data subsets, potentially compromising sensitive business information.
The operational impact of CVE-2019-2929 extends beyond the immediate PeopleTools environment, as successful exploitation can affect additional Oracle products that may be integrated with PeopleSoft systems. This cascading effect represents a significant concern for enterprise environments where PeopleSoft serves as a foundational platform for business processes. The confidentiality and integrity impacts, rated at level L (low) in the CVSS vector, indicate that while the vulnerability may not cause complete system compromise, it enables attackers to access and modify critical business data that could affect financial records, employee information, and operational processes. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) specifically indicates network-based attack accessibility with low attack complexity, no privilege requirements, and requires user interaction, while the scope change (S:C) demonstrates that the vulnerability can affect components beyond the originally targeted system.
Organizations should implement immediate mitigations including network segmentation to limit HTTP access to PeopleTools components, deployment of web application firewalls to monitor and filter HTTP requests, and implementation of robust access controls and input validation measures. The vulnerability aligns with CWE-20 (Improper Input Validation) and CWE-284 (Improper Access Control) categories, representing common security weaknesses that attackers frequently target in enterprise applications. From an ATT&CK framework perspective, this vulnerability maps to techniques involving initial access through network services and privilege escalation through data manipulation, potentially enabling adversaries to establish persistent access to critical business systems. Regular security assessments and patch management processes should be prioritized to address this vulnerability and prevent exploitation that could result in significant financial and operational damage to affected organizations.
