CVE-2025-53061 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 attacker with high privileges and network access via HTTP to compromise the system. The vulnerability enables unauthorized operations such as update, insert, or delete on PeopleSoft accessible data, as well as unauthorized read access to a subset of this data. The vulnerability is easily exploitable due to low attack complexity (AC:L) and requires no user interaction (UI:N), but it does require the attacker to have high privileges (PR:H). The scope is changed (S:C), meaning the impact extends beyond the initially vulnerable component to other related products. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N) indicates network attack vector, low complexity, high privileges, no user interaction, scope change, low confidentiality and integrity impact, and no availability impact. Although no known exploits are currently reported in the wild, the vulnerability poses a risk of unauthorized data manipulation and disclosure within PeopleSoft environments. The CWE-284 classification points to improper access control as the root cause. The absence of patch links suggests that fixes may be pending or not yet publicly released, emphasizing the need for vigilance and interim mitigations.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of data managed within PeopleSoft Enterprise PeopleTools environments. Given that PeopleSoft is widely used in sectors such as government, finance, education, and large enterprises across Europe, exploitation could lead to unauthorized data modification or disclosure, potentially affecting sensitive personal data, financial records, or operational information. The scope change implies that other integrated Oracle products could also be indirectly impacted, increasing the attack surface. This could disrupt business processes, lead to regulatory non-compliance (e.g., GDPR breaches due to unauthorized data access), and damage organizational reputation. The requirement for high privileges limits the attack to insiders or attackers who have already compromised credentials, but the network accessibility increases the risk of lateral movement and privilege escalation within corporate networks. The lack of availability impact reduces the risk of denial-of-service but does not mitigate the serious data integrity and confidentiality concerns.

1. Immediately restrict network access to PeopleSoft Enterprise PeopleTools interfaces, especially HTTP endpoints, using network segmentation, firewalls, and access control lists to limit exposure to trusted administrators only. 2. Enforce strict privilege management and audit all high-privilege accounts to detect any unauthorized or suspicious activity. 3. Monitor PeopleSoft logs and network traffic for unusual data access patterns or unauthorized modification attempts. 4. Apply Oracle patches or security updates as soon as they become available; coordinate with Oracle support to obtain early access if possible. 5. Implement multi-factor authentication (MFA) for all administrative access to PeopleSoft environments to reduce the risk of credential compromise. 6. Conduct regular security assessments and penetration testing focused on PeopleSoft components to identify and remediate potential weaknesses. 7. Educate internal teams about the vulnerability and ensure incident response plans include scenarios involving PeopleSoft compromise. 8. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block exploitation attempts targeting PeopleSoft HTTP interfaces.
