Extensis Portfolio - Admin Portal: Authenticated Unrestricted File Upload Resulting in Remote Code Execution
Extensis Portfolio v4.0 was discovered to contain an authenticated unrestricted file upload vulnerability via the component AdminFileTransferServlet.

This filename can include path traversal characters to upload the file to a specific directory. The vulnerable component is /FileTransfer/upload. At the request of the vendor, a full proof of concept script has not been generated.
