Descriptions

The Church Admin WordPress plugin before 3.4.135 does not have authorisation and CSRF in some of its action as well as requested files, allowing unauthenticated attackers to repeatedly request the "refresh-backup" action, and simultaneously keep requesting a publicly accessible temporary file generated by the plugin in order to disclose the final backup filename, which can then be fetched by the attacker to download the backup of the plugin's DB data

El plugin Church Admin de WordPress versiones anteriores a 3.4.135, no presenta autorización y CSRF en algunas de sus acciones, así como en los archivos solicitados, lo que permite a atacantes no autenticados solicitar repetidamente la acción "refresh-backup", y simultáneamente seguir solicitando un archivo temporal de acceso público generado por el plugin con el fin de divulgar el nombre del archivo de copia de seguridad final, que luego puede ser obtenido por el atacante para descargar la copia de seguridad de los datos de la base de datos del plugin

The Church Admin plugin for WordPress is vulnerable to Unauthenticated Backup Disclosure in versions up to, and including, 3.4.134. Attackers can repeatedly request the "refresh-backup" action and simultaneously request a publicly accessible temporary file generated by the plugin in order to disclose the final backup filename. Once obtaining that backup name, the plugin lacks sufficient protections to prevent accessing those files externally. This makes it possible for unauthenticated attackers to download the backup of the plugin's data once they conduct this attack, which requires a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
