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 Stored XSS 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 XSS almacenados.

The Essential Real Estate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'font[0][selector]' parameter in all versions up to, and including, 4.3.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above,]to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
