Summary
SAP NetWeaver Knowledge Management (XML Forms) contains a code injection flaw in which the selection of XSL transformations is not sufficiently restricted. An attacker with network access and a low-privilege login could trigger unauthorized XSL transformations, potentially executing arbitrary code within the application and affecting its confidentiality, integrity, and availability.

Read the original description
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.
