CVE-2025-34428

MailEnable versions prior to 10.54 contain a cleartext storage of credentials vulnerability that can lead to local credential compromise and account takeover. The product stores user and administrative passwords in plaintext within AUTH.SAV with overly permissive filesystem access. A local authenticated user with read access to this file can recover all user passwords and super-admin credentials, then use them to authenticate to MailEnable services such as POP3, SMTP, or the webmail interface, enabling unauthorized mailbox access and administrative control.

Summary		(es) Versiones de MailEnable anteriores a 10.54 contienen una vulnerabilidad de almacenamiento de credenciales en texto claro que puede conducir al compromiso local de credenciales y a la toma de control de cuentas. El producto almacena las contraseñas de usuario y administrativas en texto claro dentro de AUTH.SAV con un acceso excesivamente permisivo al sistema de archivos. Un usuario local autenticado con acceso de lectura a este archivo puede recuperar todas las contraseñas de usuario y las credenciales de superadministrador, y luego usarlas para autenticarse en servicios de MailEnable como POP3, SMTP o la interfaz de webmail, lo que permite el acceso no autorizado al buzón y el control administrativo.
