CVE-2026-9508

Incorrect permission settings on a critical resource in Suprema BioStar 2 (versions 2.9.3 through 2.9.11) that allow backup files to be publicly exposed when the administrator configures their path within the NGINX webroot. This vulnerability allows an attacker with network access to directly download backup ZIP files via ‘http(s)://[server]/download/…’ without requiring authentication. This exposes highly sensitive information that can lead to server impersonation, unauthorized access to databases, and lateral movement.

Summary		(es) Configuración de permisos incorrecta en un recurso crítico en Suprema BioStar 2 (versiones 2.9.3 a 2.9.11) que permite que los archivos de copia de seguridad queden expuestos públicamente cuando el administrador configura su ruta dentro del directorio raíz web de NGINX. Esta vulnerabilidad permite a un atacante con acceso a la red descargar directamente archivos ZIP de copia de seguridad a través de 'http(s)://[server]/download/…' sin requerir autenticación. Esto expone información altamente sensible que puede conducir a la suplantación del servidor, acceso no autorizado a bases de datos y movimiento lateral.
