At a glance
CVE-2024-47312 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Classic Editor and Classic Widgets WordPress plugin, affecting versions <= 1.4.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.4.2; sites on affected versions should update now. Disclosed September 2024, reported by Hakiduck.
Vulnerability Overview
The Classic Editor and Classic Widgets plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 1.4.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
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.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Classic Editor and Classic Widgets <= 1.4.1 takes an account at Subscriber level or above. 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 Classic Editor and Classic Widgets the fix is 1.4.2: builds <= 1.4.1 are affected, anything from 1.4.2 onward is not.
Remediation
Update to version 1.4.2, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Classic Editor and Classic Widgets 1.4.2 closes this, and updating the plugin is the step that ends it.
