Name of the Vulnerable Software and Affected Versions MailEnable versions prior to 10.54

Description MailEnable versions prior to 10.54 store user and administrative passwords in plaintext within the AUTH.TAB file, which has overly permissive filesystem access. A local authenticated user with read access to this file can recover all user passwords and super-admin credentials. These credentials can then be used to authenticate to MailEnable services such as POP3, SMTP, or the webmail interface, potentially enabling unauthorized mailbox access and administrative control.

Recommendations Update MailEnable to version 10.54 or later.
