CVE-2017-10027 in PeopleSoft Enterprise PeopleTools
Summary
by MITRE
Vulnerability in the PeopleSoft Enterprise PeopleTools component of Oracle PeopleSoft Products (subcomponent: Fluid Homepage & Navigation). Supported versions that are affected are 8.54 and 8.55. Easily exploitable vulnerability allows low privileged 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 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 CVE-2017-10027 vulnerability resides within Oracle PeopleSoft Enterprise PeopleTools, specifically affecting the Fluid Homepage & Navigation subcomponent. This security flaw impacts versions 8.54 and 8.55 of the PeopleTools suite, representing a significant concern for organizations utilizing Oracle's enterprise application platform. The vulnerability's classification as easily exploitable indicates that attackers can leverage relatively straightforward methods to compromise affected systems, making it particularly dangerous in production environments where PeopleSoft applications handle sensitive business data and processes. The attack vector requires network access via HTTP, suggesting that the vulnerability can be exploited remotely without requiring physical access to the target system.
The technical nature of this vulnerability stems from insufficient input validation and access control mechanisms within the Fluid Homepage & Navigation functionality. Attackers with low privileges can potentially manipulate the application's navigation and homepage components to gain unauthorized access to underlying data. This flaw operates through a combination of inadequate authorization checks and potentially vulnerable data handling procedures that allow malicious actors to perform unauthorized operations. The vulnerability's impact extends beyond the immediate PeopleTools component, as successful exploitation can affect additional products within the PeopleSoft ecosystem, creating cascading security implications throughout the enterprise's application infrastructure. The CVSS 3.0 score of 5.4 reflects the moderate severity of this vulnerability, with particular emphasis on confidentiality and integrity impacts.
Operational consequences of exploiting CVE-2017-10027 can be substantial for organizations relying on PeopleSoft applications. The vulnerability enables unauthorized update, insert, and delete operations on sensitive data, while also providing unauthorized read access to data subsets within the PeopleTools accessible environment. This dual impact on both data integrity and confidentiality creates multiple attack surfaces for malicious actors seeking to compromise enterprise data. The requirement for human interaction from a person other than the attacker suggests that social engineering or targeted phishing campaigns may be necessary to initially gain access, but once the vulnerability is exploited, attackers can perform sustained operations against the system. The attack scenario typically involves an authenticated user being tricked into interacting with malicious content, which then leverages the vulnerability to escalate privileges or access restricted data.
Organizations should implement comprehensive mitigation strategies to address this vulnerability, beginning with immediate patch deployment from Oracle to resolve the underlying access control issues. Network segmentation and monitoring should be enhanced to detect suspicious HTTP traffic patterns that might indicate exploitation attempts. The vulnerability aligns with CWE-284 (Improper Access Control) and represents a specific implementation of inadequate privilege management within enterprise application frameworks. Security controls should include mandatory access controls, regular vulnerability assessments, and enhanced user behavior monitoring to detect anomalous activities. Additionally, organizations should review their PeopleSoft application configurations and implement principle of least privilege principles to minimize the potential impact of successful exploitation. The ATT&CK framework categorizes this vulnerability under privilege escalation and credential access techniques, emphasizing the need for layered security approaches that go beyond traditional perimeter defenses to protect against internal threats and compromised user accounts.
