Vulnerability Overview
The Login/Signup Popup, Waitlist Woocommerce ( Back in stock notifier ), and Side Cart Woocommerce (Ajax) WordPress plugins by XootiX are vulnerable to Cross-Site Request Forgery via the save_settings function found in the ~/includes/xoo-framework/admin/class-xoo-admin-settings.php file which makes it possible for attackers to update arbitrary options on a site that can be used to create an administrative user account and grant full privileged access to a compromised site. This affects versions <= 2.2 in Login/Signup Popup, versions <= 2.5.1 in Waitlist Woocommerce ( Back in stock notifier ), and versions <= 2.0 in Side Cart Woocommerce (Ajax).
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Waitlist Woocommerce ( Back in stock notifier ) <= 2.5.1 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Waitlist Woocommerce ( Back in stock notifier ) the fix is 2.5.2: builds <= 2.5.1 are affected, anything from 2.5.2 onward is not.
Remediation
Update to version 2.5.2, or a newer patched version
