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 3643865 was released on 09.09.2025 and deals with "[CVE-2025-42922] Insecure File Operations vulnerability in SAP NetWeaver AS Java (Deploy Web Service)" within Java. We advice you to follow the instructions, to resolve missing authentication check with a hot news potential for exploitation in component BC-JAS-DPL.

According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as monthly patch process.

Risk specification

This note has been re-released with the updated link to the KBA in the 'Workaround' section (no customer action is required). SAP NetWeaver AS Java allows an authenticated attacker to upload an arbitrary file using a flaw in a web service, resulting in the ability to execute this file and gain full control over the system.

Solution

SAP NetWeaver AS Java now restricts access to the affected web service to administrative users only, preventing non-administrative users from uploading arbitrary files through this interface.  Alternativly, the consulting team has proposed the following: "As a workaround, the vulnerable service com.sap.engine.services.dc.wsgate can be deactivated.". The suggestion may be considered, as a workaround or compensating mitigation. We recommend installing/applying the correction wherever possible and as soon as possible. Base your decision on whether or not to apply the patch on your companies and systems risk perspective and consider the provided CVSS 9.9 score.

Affected System

SAP Netweaver Application Server Java is part of the SAP NetWeaver Application Platform. It provides the complete infrastructure for deploying and running Java applications.
