Official description
Due to missing verification of file type or content, SAP Supplier Relationship Management allows an authenticated attacker to upload arbitrary files. These files could include executables which might be downloaded and executed by the user which could host malware. On successful exploitation an attacker could cause high impact on confidentiality, integrity and availability of the application.

The underlying weakness: Unrestricted Upload of File with Dangerous Type
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
How developers prevent this class of flaw
- Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
