CVE-2025-42917

Vulnerability

Overview CVE-2025-42917 is an authorization bypass vulnerability in the SAP HCM Approve Timesheets Fiori 2.0 application. The application fails to perform necessary authorization checks for authenticated users, leading to an escalation of privileges. This flaw primarily impacts the integrity of the application, while confidentiality and availability remain unaffected.

Exploitation

Conditions An authenticated user can exploit this vulnerability by directly accessing functions or data that should require higher privileges. No special network position or additional authentication is required beyond a valid user session. The attack surface is limited to authenticated users within the system.

Impact

Successful exploitation allows an attacker to gain elevated privileges, enabling them to perform unauthorized actions such as approving or modifying timesheet entries beyond their intended scope. This can undermine the trustworthiness of approval workflows and data integrity.

Mitigation

SAP has released a security note addressing this issue as part of its regular Security Patch Day. Users are strongly advised to apply the latest available patch to remediate the vulnerability [1].
