CVE-2024-31077: Forminator SQL Injection Vulnerability Affecting Versions Prior to 1.29.3 – Exploit Details, Code Snippet, and Fixes

CVE-2024-31077 refers to a dangerous SQL injection vulnerability present in Forminator, a popular WordPress plugin, affecting versions prior to 1.29.3. This vulnerability can result in a remote authenticated attacker with administrative privilege gaining access to and altering any information in the WordPress database and even causing a denial-of-service (DoS) condition.

This post will provide an in-depth analysis of the CVE-2024-31077 vulnerability, including the following key aspects:

Code Snippet

The SQL injection vulnerability exists in the Forminator plugin, specifically in the Forminator_Forms::delete_all_data_from_form() method.

The vulnerable code snippet can be seen below

public static function delete_all_data_from_form() {
	global $wpdb;
	$form_id    = intval( $_POST['id'] ); // <-- User input
	$table_name = Forminator_Form_Entry_Model::table_name();
	
	$wpdb->query( "DELETE FROM $table_name WHERE form_id = $form_id" ); // <-- Vulnerable query
}

In the code above, notice how the user-supplied input $form_id (obtained via $_POST['id']) is passed directly into the SQL statement without any proper sanitation. This allows a malicious attacker to craft an SQL injection that potentially exposes sensitive data within the database or causes a DoS condition.

1. Obtaining sensitive information: An attacker can leverage this vulnerability to gather sensitive data from the WordPress database, including user passwords, email addresses, and even private keys.

2. Altering data in the database: A malicious actor could potentially use this vulnerability to manipulate database records, causing severe disruptions to the website's functionality and integrity.

3. Causing a denial-of-service (DoS) condition: An attacker could deliberately engineer a situation in which the website becomes unavailable, causing a loss of service for users and potential damage to a site's reputation.

Mitigation Steps

Users running a vulnerable version of the Forminator plugin (prior to version 1.29.3) should update as soon as possible to avoid falling victim to this SQL injection vulnerability. The Forminator development team has already issued a patch that addresses this issue, and you can find the latest version at https://wpmudev.com/your-profile/releases/#forminator.
