                    This module exploits a path traversal flaw in Novell ZENworks Asset Management
                7.5. By exploiting the CatchFileServlet, an attacker can upload a malicious file
                outside of the MalibuUploadDirectory and then make a secondary request that allows
                for arbitrary code execution.
