Advisory

SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for vulnerabilities reported by external researchers and their customers every second Tuesday of the month.

SAP Note 2960815 was released on 08.09.2020 and deals with "[Multiple CVEs] Improper Input Validation in SAP 3D Visual Enterprise Viewer" within SAP 3D Visual Enterprise . We advice you to follow the instructions, to resolve denial of service (dos) with a medium potential for exploitation in component CA-VE-VEV.

According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as part of maintenance.

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.
