It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.2.2; sites on affected versions should update now. Disclosed March 2023, reported by muhga.

Vulnerability Overview

The WP OnlineSupport, Essential Plugin Popup Anything plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.2.1. This is due to missing nonce validation on the popupaoc_register_settings() function. This makes it possible for unauthenticated attackers to reset the plugin's settings granted they can trick a site administrator into performing an action such as clicking on a link.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Popup Maker and Popup Anything < 2.2.2 carries this weakness at popupaoc_register_settings(), and reaching it 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 Popup Maker and Popup Anything the fix is 2.2.2: builds < 2.2.2 are affected, anything from 2.2.2 onward is not.

Remediation

Update to version 2.2.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Popup Maker and Popup Anything: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Popup Maker and Popup Anything 2.2.2 closes this, and updating the plugin is the step that ends it.
