Description

The byterange filter in the Apache HTTP Server 2.0.x through 2.0.64, and 2.2.x through 2.2.19 allows remote attackers to cause a denial of service (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges, exploit called "Apache Killer"

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/apache_range_dos
msf auxiliary(apache_range_dos) > show actions
    ...actions...
msf auxiliary(apache_range_dos) > set ACTION < action-name >
msf auxiliary(apache_range_dos) > show options
    ...show and set options...
msf auxiliary(apache_range_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.
