At a glance

CVE-2022-23976 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Access Demo Importer WordPress plugin, affecting versions <= 1.0.7. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.0.8; sites on affected versions should update now. Disclosed January 2022, reported by R3N0.

Vulnerability Overview

The Access Demo Importer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.7 due to missing nonce validation on the `adi_demo_data_reset` function called via an AJAX action. This makes it possible for an attacker to reset all data on the site, including posts, pages, and media.

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 integrity, availability.

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

Reaching this weakness in Access Demo Importer <= 1.0.7 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 Access Demo Importer the fix is 1.0.8: builds <= 1.0.7 are affected, anything from 1.0.8 onward is not.

Remediation

Update to version 1.0.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Access Demo Importer: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Access Demo Importer 1.0.8 closes this, and updating the plugin is the step that ends it.
