Metasploit HTTP(S) handler DoS



This module exploits the Metasploit HTTP(S) handler by sending a specially crafted HTTP request that gets added as a resource handler. Resources (which come from the external connections) are evaluated as RegEx in the handler server. Specially crafted input can trigger Gentle, Soft and Hard DoS. Tested against Metasploit 5.0.20.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/dos/http/metasploit_httphandler_dos
msf auxiliary(metasploit_httphandler_dos) > show actions
msf auxiliary(metasploit_httphandler_dos) > set ACTION < action-name >
msf auxiliary(metasploit_httphandler_dos) > show options
    ...show and set options...
msf auxiliary(metasploit_httphandler_dos) > run 

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.
