Descriptions

The Essential Real Estate WordPress plugin before 4.4.0 does not apply proper capability checks on its AJAX actions, which among other things, allow attackers with a subscriber account to conduct Denial of Service attacks.

El complemento Essential Real Estate de WordPress anterior a 4.4.0 no aplica comprobaciones de capacidad adecuadas en sus acciones AJAX, que, entre otras cosas, permiten a atacantes con una cuenta de suscriptor realizar ataques de denegación de servicio.

The Essential Real Estate plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the gsf_save_options AJAX action in all versions up to, and including, 4.3.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the plugin's settings which can lead to a denial of service.
