Unrestricted file upload

SAP NetWeaver (Knowledge Management), versions - 7.30, 7.31, 7.40, 7.50, allows an unauthenticated attacker to upload a malicious file and also to access, modify or make unavailable existing files but the impact is limited to the files themselves and is restricted by other policies such as access control lists and other upload file size restrictions, leading to Unrestricted File Upload.
