Descriptions

Auth. SQL Injection (SQLi) vulnerability in Quiz And Survey Master plugin <= 7.3.4 on WordPress.

Autenticación. Vulnerabilidad de inyección SQL (SQLi) en el complemento Quiz And Survey Master <= 7.3.4 en WordPress.

The Quiz And Survey Master plugin for WordPress is vulnerable to SQL Injection via several parameters in versions up to, and including, 7.3.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with high-level privileges, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
