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 specificationSAP NetWeaver Application Server ABAP allows a high privileged attacker to inject code by executing an ABAP report when the attacker has access to the local SAP system.
The program RDDPUTJR will be removed from the product. Although an alternative solution exists, it is advisable to apply the correction!
