cFolders (Collaboration Folders) is the SAP web-based application for collaborative sharing of information.
cFolders is part of a suite of applications powered by SAP NetWeaver that integrates project management,
knowledge management and resource management in collaborative inter-enterprise and intra-enterprise

cFolders is integrated to SAP ECC, SAP Product Lifecycle
Management (PLM), SAP Supplier Relationship Management (SRM), SAP Knowledge Management and SAP
NetWeaver cRooms (collaboration rooms). Virtual teams can access, view online, subscribe for changes, and
redline documents and product information. Partners and suppliers can interact with cFolders in predefined
collaborative or competitive scenarios.


Multiple Stored XSS vulnerabilities were found in SAP Cfolders engine. The user who is a business partner of an
organization can steal Administrator's cookie by inserting javascript into CFolders system.
He can do this using 2 Stored XSS vulnerabilities.

SAP Server doesn't associate session identificators with users IP-adress or with any other additional data.
IT autenticates users ONLY by cookies. So any user who can steal Administrator's cookie can use them to authenticate with administrative rights.

1. A user can insert javascript code into site using a link creation option

He can inject javascript code into LINK field on the page


example LINK value:" onmouseover="alert(document.cookie)">

In this case when Administrator browses user folders, the script will execute.

2. The second XSS vulnerability was found in the document uploading area.
A user can create a document with a file name including javascript code.

example filename value:


To do this user must change the file name in http-request when sending a request for a file upload.

So using this vulnerability a user can steal cookie like he does in the first example.

The issue has been solved. See SAP note 1284360.
