Summary
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.
