Description

The WP Multi Store Locator Pro plugin for WordPress is vulnerable to generic SQL Injection via the 'store_locatore_search_radius' parameter in all versions up to, and including, 4.5.1 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. The injection occurs in a numeric, unquoted SQL context, meaning WordPress's wp_magic_quotes() addslashes-based protection cannot neutralize the payload, and the AJAX handler is registered on wp_ajax_nopriv_make_search_request with no nonce or capability check, making it fully accessible without authentication.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
