At a glance

CVE-2020-12076 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Data Tables Generator by Supsystic WordPress plugin, affecting versions <= 1.9.91. 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 1.9.92; sites on affected versions should update now. Disclosed March 2020, reported by Chloe Chamberland.

Vulnerability Overview

The Data Tables Generator by Supsystic plugin before 1.9.92 for WordPress lacks CSRF nonce checks for AJAX actions. One consequence of this is stored XSS.

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 Data Tables Generator by Supsystic <= 1.9.91 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 Data Tables Generator by Supsystic the fix is 1.9.92: builds <= 1.9.91 are affected, anything from 1.9.92 onward is not.

Remediation

Update to version 1.9.92, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Data Tables Generator by Supsystic: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Data Tables Generator by Supsystic 1.9.92 closes this, and updating the plugin is the step that ends it.
