CVE-2025-34396

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 MEAINFY.DLL from its application directo without sufficient integrity validation or secure search order. If the DLL is missing or attacker-writable locations in the search path are used, a local attacker with write permissions to the directory can plant a malicious MEAINFY.DLL. When the executable is launched, it loads the attacker-controlled library and executes code with the privileges of the process, enabling local privilege escalation when run with elevated rights.

Summary		(es) Las 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 MEAINFY.DLL desde su directorio de aplicación sin suficiente validación de integridad u orden de búsqueda seguro. Si la DLL falta o se utilizan ubicaciones escribibles por el atacante en la ruta de búsqueda, un atacante local con permisos de escritura en el directorio puede colocar una MEAINFY.DLL maliciosa. Cuando se inicia el ejecutable, carga la biblioteca controlada por el atacante y ejecuta código con los privilegios del proceso, lo que permite la escalada de privilegios local cuando se ejecuta con derechos elevados.
