Enumeration

Users

  • In /user/register just try to create a username and if the name is already taken it will be notified: The name admin is already taken.
  • If you request a new password for an existing username: Unable to send e-mail. Contact the site administrator if the problem persists.
  • If you request a new password for a non-existent username: Sorry, loremipsum is not recognized as a user name or an e-mail address
  • Accessing /user/<number> you can see the number of existing users, in this case is 2 as /users/3 returns a not found error:

Pages

  • Fuzz From http://drupal.local/node/1 To http://drupal.local/node/500. You could find hidden pages (test, dev) which are not referenced by the search engines.
