Vulnerability in Mailenable

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.
