D2 Elliot provides several hundreds of exploits for web application. When you get remote command execution on a web application you could need to go more deeper on the server and on the network. Using a MOSDEF node to do that seems an efficient way.
In D2 Exploitation Pack for Immunity CANVAS you can find d2sec_elliot, it makes available to CANVAS all the Elliot exploits which can give you a remote command execution (RFI, RCE or File Upload vulnerability for example). The most interesting part of this module is the ability to automatically gain a MOSDEF node from an Elliot exploit.
The following video shows you how you can get a MOSDEF node on target server through an Elliot exploit.
