CVE-2025-34423

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

Summary		(es) Versiones de MailEnable anteriores a la 10.54 contienen una vulnerabilidad de carga de DLL insegura que puede conducir a la ejecución de código arbitrario local. El ejecutable administrativo de MailEnable intenta cargar MEAIAU.DLL desde su directorio de instalación sin suficiente validación de integridad o un orden de búsqueda seguro. Un atacante local con acceso de escritura a ese directorio puede plantar una MEAIAU.DLL maliciosa, que luego se carga al ejecutarse, lo que resulta en la ejecución de código controlado por el atacante con los privilegios del proceso.
