Summary
by MITRE • 08/19/2026
Vulnerability in the PeopleSoft Enterprise FIN Lease Administration product of Oracle PeopleSoft (component: Lease Administration). The supported version that is affected is 9.2. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where PeopleSoft Enterprise FIN Lease Administration executes to compromise PeopleSoft Enterprise FIN Lease Administration. While the vulnerability is in PeopleSoft Enterprise FIN Lease Administration, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all PeopleSoft Enterprise FIN Lease Administration accessible data as well as unauthorized access to critical data or complete access to all PeopleSoft Enterprise FIN Lease Administration accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle PeopleSoft Enterprise FIN Lease Administration product, specifically affecting version 9.2 of the Lease Administration component. This security flaw presents a significant risk to organizations relying on this enterprise resource planning module for managing financial lease obligations and related accounting data. The nature of the defect is characterized as difficult to exploit, which implies that an attacker must possess specific knowledge or conditions beyond basic access to successfully leverage the issue. However, despite the high complexity required for exploitation, the potential impact of a successful attack is severe, affecting not only the integrity and confidentiality of the targeted application but potentially extending its influence to other connected products within the broader Oracle ecosystem due to scope changes inherent in how data flows between integrated systems.
From an operational perspective, this vulnerability allows a low-privileged attacker who has already established logon access to the infrastructure hosting PeopleSoft Enterprise FIN Lease Administration to compromise the system's security posture. The requirement for local or network-level authentication means that external remote attackers without prior credentials cannot directly exploit this flaw from outside the trusted perimeter. Instead, the threat originates from insider threats or compromised accounts with limited privileges within the internal network environment. Once an attacker gains initial access through legitimate but low-privilege credentials, they can leverage this vulnerability to escalate their influence over critical data assets. This scenario highlights a classic privilege escalation pathway where insufficient separation of duties or overly permissive default configurations allow lower-level users to perform actions reserved for administrators or higher-tier roles.
The technical impact of exploiting this flaw is substantial, primarily targeting the confidentiality and integrity aspects of the Common Vulnerability Scoring System version 3.1 framework. A successful exploitation results in unauthorized creation, deletion, or modification access to critical data within the Lease Administration module. This means an attacker could alter lease terms, delete financial records essential for auditing and compliance, or inject fraudulent entries that distort financial reporting accuracy. Furthermore, the vulnerability grants complete access to all PeopleSoft Enterprise FIN Lease Administration accessible data, leading to a high level of confidentiality impact where sensitive proprietary information regarding leases, vendors, and internal financial structures becomes exposed. The CVSS 3.1 base score of 7.5 reflects these serious consequences, driven by vectors indicating local attack vector (AV:L), high complexity (AC:H), low required privileges (PR:L), no user interaction (UI:N), and a changed scope (S:C) which amplifies the risk to surrounding systems.
In terms of industry standard classifications, this vulnerability aligns with CWE-269 Improper Privilege Management or potentially CWE-862 Missing Authorization if the flaw involves bypassing access controls for specific data objects. The attack pattern corresponds to MITRE ATT&CK techniques such as T1078 Valid Accounts, where attackers use legitimate credentials to move laterally and escalate privileges within a networked environment. Because the scope changes upon exploitation, it also touches upon lateral movement dynamics where compromising one component provides footholds for attacking adjacent services that share database connections or authentication tokens. This interconnectedness underscores the importance of treating application-level vulnerabilities as potential gateways for broader infrastructure compromise rather than isolated incidents confined to a single software module.
Mitigation strategies must focus on both immediate remediation and long-term architectural hardening. The primary defense is applying the latest security patches provided by Oracle, which address the underlying code flaws allowing unauthorized data manipulation or access. Organizations should ensure that their PeopleSoft environments are updated to supported versions with all critical bundles applied. Beyond patching, implementing strict role-based access control (RBAC) policies is essential to minimize the attack surface for low-privileged users. Administrators should review and restrict permissions granted to standard user accounts, ensuring they do not possess unnecessary write or delete capabilities on sensitive lease data tables. Additionally, deploying network segmentation can limit the ability of compromised low-privilege systems to communicate with critical database servers hosting PeopleSoft applications.
Monitoring and detection mechanisms should be enhanced to identify anomalous activities indicative of exploitation attempts. Since the vulnerability requires local infrastructure access, logging all authentication events and subsequent high-level actions taken by low-privileged accounts is crucial for forensic analysis and early warning. Security Information and Event Management (SIEM) systems should be configured to alert on unusual patterns such as bulk data deletions or modifications occurring outside normal business hours from non-administrative accounts. Regular vulnerability assessments and penetration testing that simulate insider threats can help identify similar weaknesses before they are exploited by malicious actors who have gained a foothold within the network perimeter through other means like phishing or credential theft.
