Descriptions

The POST SMTP Mailer WordPress plugin before 2.8.7 does not properly sanitise and escape several parameters before using them in SQL statements, leading to a SQL injection exploitable by high privilege users such as admin.

El complemento POST SMTP Mailer de WordPress anterior a 2.8.7 no sanitiza ni escapa adecuadamente varios parámetros antes de usarlos en sentencias SQL, lo que genera una inyección de SQL explotable por usuarios con privilegios elevados, como el administrador.

The POST SMTP – The #1 WordPress SMTP Plugin with Advanced Email Logging and Delivery Failure Notifications plugin for WordPress is vulnerable to time-based SQL Injection via the selected parameter in all versions up to, and including, 2.8.6 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 administrator access or higher to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
