What is CVE-2025-34422?

MailEnable software contains a vulnerability in versions prior to 10.54 that allows local arbitrary code execution through unsafe DLL loading. The MailEnable administrative executable is designed to load the MEAIPC.DLL from its installation directory without proper integrity validation or a secure search order. An attacker with write access to this directory could insert a malicious MEAIPC.DLL, leading to the execution of unauthorized code with the same privileges as the MailEnable process. Addressing this vulnerability is essential for maintaining the security and integrity of systems running MailEnable.
