CVE-2025-42926Network attack vector

Unauthenticated internal-file disclosure via missing access check

Published Sep 9, 2025 · Updated Sep 9, 2025

Missing authentication in SAP NetWeaver Application Server Java WD-RUNTIME 7.50 allows remote attackers to read internal web application files. The web application serves requests for internal files without verifying that the requester has authenticated; SAP has not publicly identified the affected endpoint or request parameters. Network reachability to the affected application is sufficient, and successful exploitation discloses limited sensitive system information without changing data or interrupting service.
