Description

The version of SAP NetWeaver Application Server Java detected on the remote host is affected by a code injection vulnerability as referenced in SAP Security Note 3809153:

- SAP NetWeaver Knowledge Management (XML Forms) does not sufficiently restrict the selection of XSL transformations processed by the affected functionality. Under certain conditions, an authenticated user with access to the affected functionality could cause an unauthorized XSL transformation to be processed, potentially leading to arbitrary code execution in the application context. Successful exploitation could impact the confidentiality, integrity and availability of the application. (CVE-2026-109803)
