Missing authority checks are still the most common security defect related to authorizations in custom code. Since SAP uses an explicit authorization model, an authority checks must be coded in order to be executed. If an explicit check is not coded, all users have access. This type of vulnerability not only exists in SAP standard it also exists in customer coding. Check your custom developments for vulnerabilities that pose a risk to your systems. SecurityBridge helps detect code vulnerabilities before they are implemented in production.
Risk specification
SAP S/4 HANA Manage Bank Statements allows an authenticated attacker to modify 'read only' fields via HTTP MERGE method, resulting in violation of integrity.Solution
The read-only fields in the GUI have also been restricted as read-only in the business object in the backend. It is therefore no longer possible to change the content of these fields using the HTTP MERGE method. Circumstances exist that prevent the timely installation of a patch provided by the manufacturer. In such cases, you may consider applying the suggested workaround as a temporary or compensating mitigation: "Update in progress".
