CVE-2025-53065 is a vulnerability identified in Oracle PeopleSoft Enterprise PeopleTools, specifically affecting versions 8.60, 8.61, and 8.62. The flaw resides in the PIA Core Technology component and allows an unauthenticated attacker with network access via HTTP to exploit the system. The attack vector requires no privileges and low attack complexity, but successful exploitation necessitates user interaction from a third party, such as clicking a malicious link or opening a crafted file. Exploitation can lead to unauthorized read access and unauthorized modification (update, insert, delete) of some PeopleSoft accessible data, compromising confidentiality and integrity. The vulnerability does not affect availability. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N) indicates network attack vector, low complexity, no privileges required, user interaction required, unchanged scope, and low confidentiality and integrity impacts. The CWE-125 classification suggests a possible out-of-bounds read or similar memory handling issue. No known exploits are currently reported in the wild, and no official patches have been linked yet, indicating the need for vigilance and interim mitigations. Given PeopleSoft's role in enterprise resource planning, human capital management, and financial systems, exploitation could lead to unauthorized data manipulation and exposure, affecting business operations and compliance.

For European organizations, the impact of CVE-2025-53065 could be significant due to the widespread adoption of Oracle PeopleSoft in sectors such as finance, government, healthcare, and manufacturing. Unauthorized read access could expose sensitive personal data, financial records, or strategic business information, leading to privacy violations and regulatory non-compliance under GDPR. Unauthorized data modification could disrupt business processes, cause financial inaccuracies, or corrupt critical records, potentially leading to operational downtime or reputational damage. The requirement for user interaction means phishing or social engineering campaigns could be leveraged to exploit this vulnerability, increasing risk in environments with less mature security awareness. The lack of availability impact reduces the risk of denial-of-service conditions but does not diminish the threat to data integrity and confidentiality. Organizations with PeopleSoft systems exposed to the internet or accessible networks face higher risk, especially if they have not implemented network segmentation or strict access controls.

1. Restrict network access to PeopleSoft Enterprise PeopleTools HTTP interfaces by implementing strict firewall rules and network segmentation to limit exposure to trusted internal networks only. 2. Enhance user awareness training focused on phishing and social engineering to reduce the likelihood of successful user interaction exploitation. 3. Monitor PeopleSoft logs and network traffic for unusual activity indicative of exploitation attempts, such as unexpected data modification or access patterns. 4. Apply principle of least privilege to PeopleSoft user accounts and services to minimize potential damage from unauthorized access. 5. Regularly review and update PeopleSoft configurations to disable unnecessary services or features that could be exploited. 6. Engage with Oracle support and subscribe to security advisories to obtain patches or workarounds as soon as they become available. 7. Consider deploying web application firewalls (WAF) with custom rules to detect and block suspicious HTTP requests targeting PeopleSoft endpoints. 8. Conduct penetration testing and vulnerability assessments focused on PeopleSoft environments to identify and remediate other potential weaknesses.
