Vulnerability Overview

The Poll, Survey & Quiz Maker Plugin by Opinion Stage plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 19.12.0. This is due to missing or insufficient nonce validation on the disconnect_account_action function. This makes it possible for unauthenticated attackers to disconnect the site from the Opinion Stage platform integration via a forged request 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)

Reaching this weakness in Quiz Maker, Poll Maker & Survey Maker by Opinion Stage <= 19.12.0 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 Quiz Maker, Poll Maker & Survey Maker by Opinion Stage the fix is 19.12.1: builds <= 19.12.0 are affected, anything from 19.12.1 onward is not.

Remediation

Update to version 19.12.1, or a newer patched version
