At a glance

CVE-2022-0180 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Quiz and Survey Master (QSM) WordPress plugin, affecting versions <= 7.3.5. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 7.3.7; sites on affected versions should update now. Disclosed January 2022, reported by Daiki Sueyoshi.

Vulnerability Overview

Cross-site request forgery (CSRF) vulnerability in Quiz And Survey Master versions prior to 7.3.7 allows a remote attacker to hijack the authentication of administrators and conduct arbitrary operations via a specially crafted web page.

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 Quiz and Survey Master (QSM) <= 7.3.5 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 and Survey Master (QSM) the fix is 7.3.7: builds <= 7.3.5 are affected, anything from 7.3.7 onward is not.

Remediation

Update to version 7.3.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Quiz and Survey Master (QSM): WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Quiz and Survey Master (QSM) 7.3.7 closes this, and updating the plugin is the step that ends it.
