CVE-2017-10256 in PeopleSoft Enterprise PRTL Interaction Hub
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise PRTL Interaction Hub component of Oracle PeopleSoft Products (subcomponent: EPPCM_HIER_TOP). The supported version that is affected is 9.1.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise PeopleSoft Enterprise PRTL Interaction Hub. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PeopleSoft Enterprise PRTL Interaction Hub, 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 PRTL Interaction Hub accessible data as well as unauthorized read access to a subset of PeopleSoft Enterprise PRTL Interaction Hub 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 CVE-2017-10256 vulnerability resides within Oracle PeopleSoft Enterprise PRTL Interaction Hub component, specifically in the EPPCM_HIER_TOP subcomponent, affecting version 9.1.0. This represents a critical security flaw that demonstrates the inherent risks present in enterprise application frameworks where multiple interconnected modules can create cascading security impacts. The vulnerability architecture reveals a fundamental weakness in the authentication mechanisms of PeopleSoft applications, which are widely deployed across enterprise environments for business process management and interaction hub functionality.
This vulnerability constitutes a remote code execution risk that operates through the HTTP protocol without requiring any authentication credentials from the attacker. The flaw enables unauthenticated remote exploitation, making it particularly dangerous as it can be leveraged by attackers from external networks without prior access to the system. The CVSS 3.0 scoring system places this vulnerability at 6.1 severity level, indicating a moderate to high risk, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N clearly demonstrating that network-based attacks require low complexity, no privilege requirements, and human interaction to succeed. The classification aligns with CWE-284 (Improper Access Control) and CWE-352 (Cross-Site Request Forgery) categories, reflecting the dual nature of the vulnerability that combines access control bypass with potential data manipulation capabilities.
The operational impact of this vulnerability extends beyond the immediate PeopleSoft component, as evidenced by the CVSS score indicating a potentially significant impact on additional products within the enterprise ecosystem. Successful exploitation allows attackers to perform unauthorized data manipulation operations including update, insert, and delete actions against sensitive data within the interaction hub, while also enabling unauthorized read access to subsets of accessible data. This dual impact on both confidentiality and integrity represents a serious threat to enterprise data security, particularly in financial and business process management systems where PeopleSoft components are extensively utilized. The requirement for human interaction suggests that the vulnerability may be triggered through social engineering tactics or user-initiated actions, making it more challenging to detect and prevent.
Organizations utilizing PeopleSoft Enterprise PRTL Interaction Hub should implement immediate mitigations including network segmentation, firewall rule enforcement, and application-level access controls to limit exposure. The vulnerability demonstrates the importance of proper input validation and authentication controls in enterprise applications, aligning with ATT&CK framework techniques such as T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS). Security teams should also consider implementing web application firewalls and monitoring for suspicious HTTP traffic patterns that could indicate exploitation attempts. The vulnerability serves as a reminder of the critical need for regular security assessments and patch management processes in enterprise environments where legacy applications continue to operate without proper security updates.
