CVE-2019-2915 in PeopleSoft Enterprise PeopleTools
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise PeopleTools product of Oracle PeopleSoft (component: Fluid Core). 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-2019-2915 resides within the PeopleSoft Enterprise PeopleTools product, specifically within the Fluid Core component of Oracle PeopleSoft. This flaw affects versions 8.56 and 8.57, representing a significant security weakness that can be exploited by unauthenticated attackers who gain network access through HTTP protocols. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to leverage this weakness, making it particularly dangerous in production environments where PeopleSoft systems handle sensitive enterprise data.
The technical implementation of this vulnerability stems from insufficient access controls within the Fluid Core framework, which governs the user interface and application logic for PeopleSoft applications. Attackers can exploit this weakness to perform unauthorized operations including data modification, insertion, and deletion within the affected systems. The vulnerability's impact extends beyond the immediate PeopleTools component, potentially affecting additional Oracle products that may share underlying infrastructure or data repositories. This cascading effect increases the overall risk profile and makes the vulnerability particularly concerning for enterprise environments where PeopleSoft systems integrate with multiple other Oracle products and third-party applications.
The operational impact of CVE-2019-2915 manifests through several critical security implications that align with the CVSS 3.0 scoring of 6.1. The vulnerability enables unauthorized read access to sensitive data subsets and allows for unauthorized modification of existing data, creating both confidentiality and integrity breaches. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted user manipulation may be necessary to trigger the exploit, though this does not mitigate the overall risk. The CVSS vector analysis reveals that the attack can be conducted over a network with low complexity and no prior privileges, while the scope of impact is classified as "changed," indicating that the vulnerability can affect additional products beyond the primary target.
Organizations should implement immediate mitigations including network segmentation to restrict HTTP access to PeopleSoft systems, deployment of web application firewalls to monitor and filter malicious requests, and comprehensive patch management to upgrade to unaffected versions of PeopleSoft Enterprise PeopleTools. The vulnerability aligns with CWE-284 Access Control Issues, specifically addressing inadequate access controls that permit unauthorized modification of data. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and data manipulation, potentially enabling adversaries to achieve persistence within enterprise environments through the compromised PeopleSoft infrastructure. Regular security assessments and monitoring of user access patterns should be implemented to detect anomalous activities that may indicate exploitation attempts. The vulnerability's classification as a medium severity issue requires immediate attention from security teams to prevent potential data breaches that could compromise sensitive enterprise information and business operations.
