Apache "mod_userdir" User Enumeration

Created
05/30/2018

Description

Apache with the UserDir directive enabled generates different error codes when a username exists and there is no public_html directory and when the username does not exist, which could allow remote attackers to determine valid usernames on the server.

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/scanner/http/apache_userdir_enum
msf auxiliary(apache_userdir_enum) > show actions
    ...actions...
msf auxiliary(apache_userdir_enum) > set ACTION < action-name >
msf auxiliary(apache_userdir_enum) > show options
    ...show and set options...
msf auxiliary(apache_userdir_enum) > 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.
