At a glance

CVE-2021-24919 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Wicked Folders WordPress plugin, affecting versions <= 2.18.9. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.18.10; sites on affected versions should update now. Disclosed December 2021, reported by Krzysztof Zając.

Vulnerability Overview

The Wicked Folders WordPress plugin before 2.18.10 does not sanitise and escape the folder_id parameter before using it in a SQL statement in the wicked_folders_save_sort_order AJAX action, available to any authenticated user. leading to an SQL injection

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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Reaching this weakness in Wicked Folders <= 2.18.9 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.

A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Wicked Folders the fix is 2.18.10: builds <= 2.18.9 are affected, anything from 2.18.10 onward is not.

Remediation

Update to version 2.18.10, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Wicked Folders: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Wicked Folders 2.18.10 closes this, and updating the plugin is the step that ends it.
