CVE-2025-34419MailEnable < 10.54 DLL Hijacking via Unsafe Loading of MEAISM.DLL
High 8.5
In plain English
A high-severity uncontrolled search path in MailEnable from MailEnable. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 6% of all known vulnerabilities).
Official 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 MEAISM.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 MEAISM.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.
