Assigner: VulnCheck

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 MEAIDP.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 MEAIDP.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 MEAIDP.DLL from its installation directory without proper integrity checks or a secure search order. A local attacker with write access to that directory can place a malicious MEAIDP.DLL, which will be loaded and executed with the privileges of the 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 could lead to unauthorized actions on the system, potentially compromising system integrity, confidentiality, and availability depending on the privileges of the process.

Detection Guidance

This vulnerability can be detected by checking if the MailEnable installation directory contains a suspicious or unauthorized MEAIDP.DLL file that could be maliciously planted. Since the vulnerability involves unsafe DLL loading from the installation directory, verifying the integrity and origin of MEAIDP.DLL is critical. Commands to list and inspect the DLL file in the installation directory (e.g., using 'dir' or 'ls' commands) and checking file hashes against known good versions can help detect the issue. Additionally, monitoring for unexpected DLL loads or unusual process behavior related to the MailEnable administrative executable may assist in detection.

Mitigation Strategies

Immediate mitigation steps include restricting write permissions to the MailEnable installation directory to prevent unauthorized users from planting a malicious MEAIDP.DLL. Ensure that only trusted administrators have write access. Additionally, update MailEnable to version 10.54 or later, where this unsafe DLL loading vulnerability is fixed. If an update is not immediately possible, consider running the administrative executable with the least privileges necessary and monitor for suspicious activity.
