CVE-2025-11759

Estado: AplazadaMedia (4.3)—

The Backup, Restore and Migrate your sites with XCloner plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.8.2. This is due to missing or incorrect nonce validation on the Xcloner_Remote_Storage:save() function. This makes it possible for unauthenticated attackers to add or modify an FTP backup configuration via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation allows an attacker to set an attacker-controlled FTP site for backup storage and exfiltrate potentially sensitive site data.

Esto se debe a la validación de nonce faltante o incorrecta en la función Xcloner_Remote_Storage:save(). Esto hace posible que atacantes no autenticados añadan o modifiquen una configuración de copia de seguridad FTP a través de una petición falsificada, siempre que puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace. La explotación exitosa permite a un atacante establecer un sitio FTP controlado por el atacante para el almacenamiento de copias de seguridad y exfiltrar datos del sitio potencialmente sensibles."
