Descriptions

The Newsletters WordPress plugin before 4.9.3 does not properly escape user-controlled parameters when they are appended to SQL queries and shell commands, which could enable an administrator to run arbitrary commands on the server.

El complemento Newsletters de WordPress anterior a 4.9.3 no escapa adecuadamente a los parámetros controlados por el usuario cuando se agregan a consultas SQL y comandos de shell, lo que podría permitir a un administrador ejecutar comandos arbitrarios en el servidor.

The Newsletters plugin for WordPress is vulnerable to Command Injection in all versions up to, and including, 4.9.2 via the emailarchive_olderthan parameter. This is due to insuffcient validation on user supplied input being passed to eval. This makes it possible for authenticated attackers, with administrator-level access and above, to execute code on the server.
