Description
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 MEAISP.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 MEAISP.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.

Executive Summary

This vulnerability exists in MailEnable versions prior to 10.54, where the administrative executable loads a DLL named MEAISP.DLL from its installation directory without proper integrity checks or secure search order. A local attacker with write access to that directory can place a malicious MEAISP.DLL, which will be loaded and executed with the privileges of the MailEnable process, allowing arbitrary code execution.

Impact Analysis

If exploited, this vulnerability allows a local attacker to execute arbitrary code with the privileges of the MailEnable administrative process. This can lead to unauthorized actions on the system, potentially compromising system integrity, confidentiality, and availability.

Mitigation Strategies

To mitigate this vulnerability, immediately restrict write access to the MailEnable installation directory to trusted users only, preventing local attackers from planting a malicious MEAISP.DLL. Additionally, upgrade MailEnable to version 10.54 or later where this issue is fixed.
