CVE-2017-10134 in PeopleSoft Enterprise FSCM
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise FSCM component of Oracle PeopleSoft Products (subcomponent: eProcurement). The supported version that is affected is 9.2. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise PeopleSoft Enterprise FSCM. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise FSCM, 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 FSCM accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise FSCM accessible data. CVSS 3.0 Base Score 5.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2017-10134 resides within the PeopleSoft Enterprise Financial Supply Chain Management (FSCM) component, specifically within the eProcurement subcomponent of Oracle PeopleSoft products. This vulnerability affects version 9.2 of the software and represents a significant security weakness that can be exploited by low-privileged attackers. The flaw operates through the HTTP protocol, requiring network access to execute attacks, making it particularly concerning for organizations with exposed web services. The vulnerability's classification as easily exploitable indicates that attackers do not require advanced technical skills or extensive resources to leverage this weakness, which significantly increases the risk to affected organizations.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the eProcurement module. Attackers can exploit this weakness to gain unauthorized access to sensitive data within the PeopleSoft Enterprise FSCM environment. The vulnerability specifically allows for unauthorized update, insert, and delete operations on certain data elements, while also enabling unauthorized read access to specific subsets of accessible data. This dual impact on both confidentiality and integrity aligns with the CVSS 3.0 base score of 5.4, which reflects the moderate severity of the threat. The attack vector requires network access, meaning that the vulnerability can be exploited remotely without requiring physical access to the target system. The CVSS vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates that the attack requires low complexity, low privilege levels, and human interaction, while the scope change (S:C) suggests that the impact extends beyond the immediate component to potentially affect additional products within the ecosystem.
The operational impact of this vulnerability extends beyond the immediate compromise of PeopleSoft data, as it can significantly affect the broader financial supply chain management operations. Organizations utilizing this component may experience data integrity issues, unauthorized modifications to procurement processes, and potential exposure of sensitive financial information. The requirement for human interaction suggests that attackers may need to trick users into performing specific actions, potentially through social engineering or phishing techniques that leverage the vulnerability. This aspect of the attack requires additional consideration of user awareness training and security awareness programs. The vulnerability's potential to impact additional products within the PeopleSoft ecosystem means that a single exploit could potentially compromise multiple interconnected systems, amplifying the overall security risk. The confidentiality and integrity impacts are particularly concerning for financial data management systems where data accuracy and protection are paramount to business operations.
Organizations should implement immediate mitigation strategies to address this vulnerability, including applying the relevant Oracle security patches and updates as released. Network segmentation and access controls should be enhanced to limit exposure of the vulnerable eProcurement component to untrusted networks. Regular monitoring and logging of access patterns can help detect potential exploitation attempts, while user training programs should address the human interaction requirement of the attack. The vulnerability aligns with CWE-20, which addresses improper input validation, and may relate to ATT&CK techniques involving credential access and privilege escalation. Additional defensive measures should include implementing web application firewalls, conducting regular security assessments, and establishing robust incident response procedures to address potential exploitation attempts. Organizations should also consider the broader implications of this vulnerability on their overall security posture and ensure that their patch management processes are comprehensive enough to address similar vulnerabilities in related components.
