Enumerate Applications on Webserver (OTG-INFO-004)

Brief Summary
A common step for testing vulnerabilities in a Web presence is to find out which particular applications are hosted on a Web Server. Many different applications, in fact, have known vulnerabilities and known attack strategies than can be exploited in order to gain remote control and/or data exploitation. In addition to this many applications are often hosted on a particular web server without reference from the main website: this is true for internal and/or extranet website which could be misconfigured or not updated due to the perception they're used only "internally". In addition to this many application use common path for administrative interfaces which can be used to guess or bruteforce administrative passwords.
