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

Description MailEnable versions prior to 10.54 have an issue where an attacker can execute code on the system. This happens because the MailEnable administrative executable loads MEAISM.DLL from the installation directory without proper checks. A local attacker who can write to that directory can place a malicious MEAISM.DLL file there. When the executable starts, it loads this malicious file, allowing the attacker to run code with the same permissions as the process.

Recommendations Update MailEnable to version 10.54 or later.
