Advisory

A note with CVSS 4.3 for component BC-IAM-IDM was released by SAP on 12.05.2020. The correction/advisory 2915429 was described with "[CVE-2020-6258] Missing Authorization check in SAP Identity Management" and affects the system type SAP IDM.

A workaround does not exist, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance.

The vulnerability addressed is missing authorization check within SAP IDM.

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 Identity Management does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges.

Solution

The authorization check of one of the attribute types, that was missing, has been added.

The advisory is valid for

  • IDMREST 8.0
