CVE-2024-32602: WooCommerce Multilingual SQLi Vulnerability

CVE-2024-32602 Overview

CVE-2024-32602 is a SQL Injection vulnerability in the OnTheGoSystems WooCommerce Multilingual & Multicurrency plugin for WordPress. The flaw affects all versions from unspecified initial releases through 5.3.3.1. The vulnerability arises from improper neutralization of special elements in SQL commands [CWE-89], allowing authenticated attackers with high privileges to inject malicious SQL statements. Successful exploitation compromises confidentiality, integrity, and availability of the underlying WordPress database.

Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the WordPress database, leading to sensitive data disclosure, record tampering, and potential site takeover.

Affected Products

OnTheGoSystems WooCommerce Multilingual & Multicurrency plugin for WordPress
All versions from initial release through 5.3.3.1
WordPress installations running the affected plugin with WooCommerce

Technical Details for CVE-2024-32602

Vulnerability Analysis

The vulnerability resides in the WooCommerce Multilingual & Multicurrency plugin, which manages multilingual product catalogs and currency conversion for WooCommerce stores. User-controlled input reaches SQL query construction without sufficient sanitization or parameterization. An authenticated attacker with high-privilege access can craft input that alters the intended query structure. The result is arbitrary read and write access to the WordPress database used by WooCommerce.

Exploitation requires network-accessible admin endpoints and valid high-privilege credentials. Once achieved, an attacker can extract customer records, order data, credentials, and configuration secrets. Attackers can also modify order states, prices, or inject persistent payloads for later abuse.

Root Cause

The root cause is improper neutralization of special elements in SQL commands [CWE-89]. The plugin concatenates untrusted parameters into SQL statements instead of using prepared statements through the WordPress $wpdb->prepare() API. This allows SQL metacharacters such as single quotes, comment tokens, and UNION clauses to escape their intended context.

Attack Vector

The attack vector is network-based and requires authentication with high privileges. The attacker sends crafted HTTP requests containing malicious SQL payloads to vulnerable plugin endpoints. No user interaction is required. See the Patchstack SQL Injection Advisory for endpoint-level technical details.

No verified proof-of-concept code is publicly available. The vulnerability mechanism is described in prose to avoid synthetic exploit examples.

Detection Methods for CVE-2024-32602

Indicators of Compromise

Unexpected SQL syntax patterns such as UNION SELECT, SLEEP(, information_schema, or comment tokens (--, /*) in HTTP request parameters targeting WordPress admin URLs
Anomalous database query volume or long-running queries from the WooCommerce Multilingual plugin context
Unexplained modifications to wp_users, wp_options, or WooCommerce order tables
Access log entries from authenticated admin sessions issuing requests with encoded SQL payloads

Detection Strategies

Inspect web server access logs for admin-authenticated requests containing SQL injection signatures against plugin endpoints
Enable WordPress database query logging and alert on queries containing tautologies or stacked statements originating from plugin code paths
Deploy a Web Application Firewall (WAF) with SQL injection rule sets tuned to WordPress and WooCommerce request patterns

Monitoring Recommendations

Monitor privileged WordPress account activity for unusual admin actions following login
Alert on schema enumeration attempts and access to wp_users or session tables outside normal application flows
Correlate plugin update status with authenticated session telemetry to identify unpatched, actively used instances

How to Mitigate CVE-2024-32602

Immediate Actions Required

Update the WooCommerce Multilingual & Multicurrency plugin to a version later than 5.3.3.1 as soon as a fixed release is available from OnTheGoSystems
Audit high-privilege WordPress accounts and rotate credentials for administrators and shop managers
Enforce multi-factor authentication for all administrative WordPress accounts to reduce risk of credential-based exploitation
Review database logs and WooCommerce order records for signs of tampering since the plugin was installed

Patch Information

The vendor advisory referenced by Patchstack confirms the vulnerability affects versions through 5.3.3.1. Administrators should apply the vendor's fixed release and verify plugin version via the WordPress admin dashboard under Plugins.

Workarounds

Deactivate the WooCommerce Multilingual & Multicurrency plugin until a patched version is installed if business requirements allow
Restrict access to the WordPress admin interface using IP allow-listing at the web server or firewall layer
Deploy WAF rules that block SQL injection patterns targeting /wp-admin/ endpoints associated with the plugin
Apply the principle of least privilege by reducing the number of accounts with administrator or shop manager roles

bash

# Example: restrict wp-admin access by IP using nginx
location ^~ /wp-admin/ {
    allow 203.0.113.0/24;
    deny all;
    try_files $uri $uri/ /index.php?$args;
}
