CVE-2025-34071

A remote code execution vulnerability in GFI Kerio Control 9.4.5 allows attackers with administrative access to upload and execute arbitrary code through the firmware upgrade feature. The system upgrade mechanism accepts unsigned .img files, which can be modified to include malicious scripts within the upgrade.sh or disk image components. These modified upgrade images are not validated for authenticity or integrity, and are executed by the system post-upload, enabling root access.

Summary		(es) Una vulnerabilidad de ejecución remota de código en GFI Kerio Control 9.4.5 permite a atacantes con acceso administrativo cargar y ejecutar código arbitrario mediante la función de actualización de firmware. El mecanismo de actualización del sistema acepta archivos .img sin firmar, que pueden modificarse para incluir scripts maliciosos en los componentes upgrade.sh o de imagen de disco. Estas imágenes de actualización modificadas no se validan en cuanto a autenticidad ni integridad, y el sistema las ejecuta después de la carga, lo que permite el acceso root.
