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 the software loads DLLs unsafely, potentially allowing a local attacker to run arbitrary code. The MailEnable administrative executable loads MEAISP.DLL from the installation directory without proper checks. An attacker with write access to this directory can place a malicious MEAISP.DLL file, which will then be executed with the privileges of the process.

Recommendations Update MailEnable to version 10.54 or later.
