This module has three actions. The first (and the default) is 'WebServer' which uses a combination of client-side and server-side techniques to fingerprint HTTP clients and then automatically exploit them. Next is 'DefangedDetection' which does only the fingerprinting part. Lastly, 'list' simply prints the names of all exploit modules that would be used by the WebServer action given the current MATCH and EXCLUDE options. Also adds a 'list' command which is the same as running with ACTION=list.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
