Unsafe DLL Loading Vulnerability in MailEnable by MailEnable

CVE-2025-34417

What is CVE-2025-34417?

MailEnable versions prior to 10.54 are susceptible to a vulnerability that allows local arbitrary code execution due to unsafe DLL loading practices. The administrative executable of MailEnable improperly loads MEAISO.DLL from its installation directory without adequate integrity checks or a secure search order. This negligence permits a local attacker, possessing write-access to the directory, to introduce a malicious MEAISO.DLL file. Once the administrative executable is initiated, it unwittingly loads the compromised DLL, thus executing attacker-controlled code with the privileges of the process, potentially leading to significant security breaches.
