CVE-2025-42914 is a security vulnerability identified in the SAP HCM (Human Capital Management) My Timesheet Fiori 2.0 application, specifically in version GBX01HR5 605. The vulnerability is classified under CWE-862, which corresponds to missing authorization. This means that the application lacks proper authorization checks, allowing an authenticated attacker who has detailed knowledge of the system to escalate privileges beyond their intended access rights. The escalation enables the attacker to perform restricted activities within the application that should normally be inaccessible. The vulnerability impacts the integrity of the application by permitting unauthorized modifications or actions, but it does not affect confidentiality or availability. The CVSS v3.1 base score is 3.1, indicating a low severity level. The vector string (AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N) reveals that the attack can be performed remotely over the network, requires low privileges but high attack complexity, no user interaction is needed, and the scope remains unchanged. No known exploits are currently reported in the wild, and no official patches have been linked yet. This vulnerability is significant because SAP HCM is widely used for managing employee data and workflows, and the My Timesheet Fiori app is a critical interface for time tracking and related HR processes. Missing authorization checks can lead to unauthorized changes in timesheet data or other HR-related records, potentially affecting payroll, compliance, and internal auditing processes.

For European organizations, the impact of this vulnerability is primarily on the integrity of HR data managed through SAP HCM systems. Unauthorized privilege escalation could allow malicious insiders or compromised accounts to alter timesheet entries, manipulate attendance records, or perform other restricted actions that could lead to financial discrepancies, compliance violations, or internal fraud. Although confidentiality and availability are not impacted, the integrity breach can undermine trust in HR processes and complicate audits. Given the strict regulatory environment in Europe regarding employee data and labor laws, such integrity issues could result in legal and financial repercussions. Organizations relying heavily on SAP HCM for workforce management, especially large enterprises and public sector entities, may face operational risks if this vulnerability is exploited. The absence of known exploits reduces immediate risk, but the potential for misuse remains, especially by attackers with system knowledge and low-level access.

To mitigate this vulnerability, European organizations should: 1) Conduct a thorough review of authorization configurations within the SAP HCM My Timesheet Fiori 2.0 application to identify and correct any missing or improperly configured authorization checks. 2) Implement strict role-based access controls (RBAC) and enforce the principle of least privilege, ensuring users have only the minimum necessary permissions. 3) Monitor user activities and audit logs specifically for unusual or unauthorized actions related to timesheet entries and privilege escalations. 4) Restrict access to the SAP HCM system to trusted networks and users, employing network segmentation and multi-factor authentication (MFA) to reduce the risk of unauthorized access. 5) Stay updated with SAP security advisories and apply patches or updates as soon as they become available. 6) Provide targeted security awareness training for administrators and users with elevated privileges to recognize and report suspicious activities. 7) Consider deploying application-level monitoring tools that can detect anomalous behavior indicative of privilege escalation attempts within the SAP environment.
