CVE-2025-34419

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.

Summary		(es) MailEnable versiones anteriores a 10.54 contienen una vulnerabilidad de carga de DLL insegura que puede conducir a ejecución local de código arbitrario. El ejecutable administrativo de MailEnable intenta cargar MEAISM.DLL desde su directorio de instalación sin una validación de integridad suficiente o un orden de búsqueda seguro. Un atacante local con acceso de escritura a ese directorio puede colocar un MEAISM.DLL malicioso, que luego se carga cuando el ejecutable se inicia, resultando en la ejecución de código controlado por el atacante con los privilegios del proceso.
