CVE-2006-6964: MailEnable Professional before 1.78 provides a cleartext user password when an administrator edits the user...

Security readout for executives and security teams

This vulnerability could expose user passwords to someone who already has MailEnable Professional administrative access. The issue is not described as unauthenticated internet compromise, but it weakens credential confidentiality and can turn an over-privileged or compromised admin account into broader mailbox exposure. Organizations running MailEnable Professional versions before 1.78 are the relevant exposure group. Risk is concentrated where many administrators have access, admin accounts are shared, or the admin interface is reachable by untrusted networks. Treat this as a targeted confidentiality issue, not a broad unauthenticated server takeover based on available evidence. Prioritize remediation for legacy MailEnable systems and environments with shared or exposed administrative access. Mitigation focus: Upgrade MailEnable Professional to version 1.78 or later.; Review MailEnable release notes and vendor guidance for the exact fixed build.; Restrict administrative access to trusted users and trusted network locations..
