At a glance

CVE-2024-13426 is a medium-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the WP-Polls WordPress plugin, affecting versions <= 2.77.2. It carries a CVSS score of 5.4 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 2.77.3; sites on affected versions should update now. Disclosed January 2025, reported by Jack Taylor.

Vulnerability Overview

The WP-Polls plugin for WordPress is vulnerable to SQL Injection via COOKIE in all versions up to, and including, 2.77.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries. Those queries are stored and results are not displayed to the attacker, which means they cannot be exploited to obtain any additional information about the database. However, a properly configured payload allows for the injection of malicious JavaScript resulting in Stored Cross-Site Scripting.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

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

Reaching this weakness in WP-Polls <= 2.77.2 takes no account at all. 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 WP-Polls the fix is 2.77.3: builds <= 2.77.2 are affected, anything from 2.77.3 onward is not.

Remediation

Update to version 2.77.3, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP-Polls 2.77.3 closes this, and updating the plugin is the step that ends it.
