CVE-2025-42914 is a vulnerability identified in the SAP HCM (Human Capital Management) My Timesheet Fiori 2.0 application, specifically related to missing authorization checks (CWE-862). This flaw allows an authenticated attacker, who possesses in-depth knowledge of the system, to escalate privileges within the application. The vulnerability arises because the application does not properly enforce authorization controls on certain operations, enabling users with limited privileges to perform actions that should be restricted. The impact is primarily on the integrity of the application, as unauthorized modifications or actions could be performed. However, confidentiality and availability are not affected by this vulnerability. The CVSS v3.1 base score is 3.1, indicating a low severity level. The vector string (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N) shows that the attack requires network access, low privileges, and high attack complexity, with no user interaction needed. The vulnerability affects version GBX01HR5 605 of the SAP HCM My Timesheet Fiori 2.0 application. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on September 9, 2025, and was reserved in April 2025. This issue is significant for organizations using SAP HCM solutions, as it could allow unauthorized privilege escalation within timesheet management, potentially leading to unauthorized data manipulation or workflow disruptions within HR processes.

For European organizations, the impact of CVE-2025-42914 is primarily on the integrity of HR-related data and processes managed through the SAP HCM My Timesheet Fiori 2.0 application. Unauthorized privilege escalation could allow attackers to alter timesheet entries, manipulate attendance records, or interfere with payroll-related data, which could lead to financial discrepancies, compliance violations, and internal audit challenges. Although confidentiality and availability are not impacted, integrity issues in HR systems can undermine trust in organizational data and lead to operational inefficiencies. Given the critical role of HR systems in workforce management and regulatory compliance (e.g., GDPR requirements for accurate employee data), even low-severity vulnerabilities can have outsized consequences if exploited. The requirement for authenticated access and in-depth system knowledge limits the attack surface but does not eliminate risk, especially in environments with complex user roles and permissions. Organizations with extensive SAP HCM deployments in Europe should be aware of this vulnerability to prevent potential misuse by insiders or attackers who have gained initial access.

To mitigate CVE-2025-42914, European organizations should implement the following specific measures: 1) Conduct a thorough review of user roles and permissions within the SAP HCM My Timesheet Fiori 2.0 application to ensure the principle of least privilege is enforced, minimizing the number of users with elevated access. 2) Implement strict monitoring and logging of timesheet-related activities to detect unusual or unauthorized changes promptly. 3) Apply network segmentation and access controls to restrict access to SAP HCM systems only to trusted and authenticated users with a legitimate business need. 4) Stay in close contact with SAP for official patches or security advisories related to this vulnerability and apply updates promptly once available. 5) Perform regular security assessments and penetration testing focused on authorization mechanisms within SAP Fiori applications to identify and remediate similar issues proactively. 6) Educate HR and IT staff about the risks associated with privilege escalation and the importance of safeguarding credentials and system access. 7) Consider deploying additional application-layer security controls or compensating controls such as multi-factor authentication (MFA) for accessing SAP HCM modules to reduce the risk of credential compromise.
