A note with CVSS 2.7 for component BC-CTS-TMS-CTR was released by SAP on 13.06.2023. The correction/advisory 3325642 was described with "[CVE-2023-32114] Denial of Service in SAP NetWeaver (Change and Transport System)" and affects the system type ABAP.
A workaround exists, according to SAP Security Advisory team. It is advisable to implement the correction as monthly patch process.
The vulnerability addressed is denial of service (dos) within ABAP.
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. Denial of Service (DoS) attacks that take a system offline may lead to significant cost for the company, studies quantify the costs in average between 4 and 5 millions dollars. Business continuity requires SAP systems staying online. The CVSS scores or vulnerability descriptions are not enough to represent how a simple bug can lead to a significant loss for companies.
Risk specification
SAP NetWeaver Change and Transport System allows an authenticated user with admin privileges to maliciously run a benchmark program repeatedly with the intent to slow down or make the server unavailable.Solution
The code in the report RSCTS_OBJ_TRACK_BENCHMARK_PREP has been removed. Although an alternative solution exists, it is advisable to apply the correction! This is the workaround, which was suggested by the SAP security experts: "Consider to secure the other reports RSCTS_OBJ_* of package SCTS_DIST_CTL_CHNG_TRCK_TOOLS, too:Use report RSCSAUTH to assign all of then to a report authorization group like NO_EXEC (or any other group which suites your need) and ensure that only approved users have an authorization for S_PROGRAM for that report authorization group.".
