Descriptions

The UserPro plugin before 4.9.17.1 for WordPress, when used on a site with the "admin" username, allows remote attackers to bypass authentication and obtain administrative access via a "true" value for the up_auto_log parameter in the QUERY_STRING to the default URI.

El plugin UserPro en versiones anteriores a la 4.9.17.1 para WordPress, cuando se utiliza en una página con el nombre de usuario "admin", permite que atacantes remotos omitan la autenticación y obtengan acceso administrativo mediante un valor "true" para el parámetro up_auto_log en QUERY_STRING en la URI por defecto.
