CVE-2025-42883Network attack vector

Malicious file storage via skipped malware scan

Published Nov 11, 2025 · Updated Nov 11, 2025

Unrestricted file upload in SAP Migration Workbench on affected SAP_BASIS releases allows remote authenticated users to store malicious files. The administrative upload path writes files to the application server without invoking the malware scan, so dangerous content is accepted unchecked. Administrative privileges are required, and the documented consequence is limited to low-integrity impact from placing a malicious file rather than automatic execution.
