The CVE-2024-4779 security vulnerability has been identified in the popular "Unlimited Elements for Elementor" plugin for WordPress, which includes free widgets, addons, and templates. This vulnerability can lead to SQL Injection through the 'data[post_ids][]' parameter in all plugin versions up to, and including, 1.5.107. The issue arises due to a lack of proper escaping on user-supplied content and insufficient preparation of existing SQL queries. Exploitation of this vulnerability can allow authenticated attackers, having contributor-level access or higher, to inject additional SQL queries into existing queries. With this capability, attackers can extract sensitive information from the WordPress database.

Code Snippet

The following code snippet demonstrates the improper usage of user-supplied input in an SQL query without proper escaping or preparation:

$post_ids = $_POST['data']['post_ids'][];
$query = "SELECT * FROM $wpdb->posts WHERE ID = $post_ids;";
$posts = $wpdb->get_results($query);

In this code, a user-supplied value in the 'data[post_ids][]' parameter is directly used within an SQL query without using prepared statements or proper escaping. This allows attackers to inject malicious SQL queries like:

1; DROP TABLE xyz;--

Exploit Details

To exploit this vulnerability, an attacker needs contributor-level access or higher in a WordPress installation running the "Unlimited Elements for Elementor" plugin. When such access is granted, the attacker can craft and send an HTTP POST request to the target WordPress website containing a specially crafted value for the 'data[post_ids][]' parameter. This malicious value can enable additional SQL queries to be executed, leading to data leak from the target WordPress database.
