Senserva AI Opinion for CVE-2020-6287

SAP NetWeaver Application Server Java lacks authentication on a critical configuration function, allowing an unauthenticated attacker to execute configuration tasks and create administrative users, a perfect CVSS 10.0 with a 95 percent EPSS score. Creating an admin user in the system that runs ERP, HR, and finance processes is about as complete a business compromise as exists. Confirmed exploitation means exposed NetWeaver Java instances have already been hit.

Do this: Patch NetWeaver Java systems immediately and audit SAP user lists for administrative accounts you did not create.
