Summary

MailEnable versions prior to 10.54 contain an unsafe DLL loading vulnerability that can lead to local arbitrary code execution. The MailEnable administrative executable attempts to load MEAISO.DLL from its installation directory without sufficient integrity validation or a secure search order. A local attacker with write access to that directory can plant a malicious MEAISO.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.

Risk Assessment

A local attacker with write access to the installation directory can execute arbitrary code with the privileges of the MailEnable process, potentially leading to full compromise of the mail server. The risk is especially relevant on multi-user systems or when the installation directory has overly permissive permissions.

Recommendation

Update MailEnable to version 10.54 or later and restrict write access to the installation directory to trusted administrative accounts only.
