LTL Freight Quotes – Worldwide Express Edition < 5.0.21 - Unauthenticated SQL Injection

Description

The LTL Freight Quotes – Worldwide Express Edition plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 5.0.20 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the /shipping-rules/shipping-rules-save.php file. 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.
