Description
An unhandled exception in Suprema BioStar 2 (Server), versions 2.9.8, 2.9.10, and 2.9.11, that allows an unauthenticated remote attacker to cause a denial of service (DoS) by sending HTTP POST requests to the ‘/api/migration’ endpoint. This request triggers a failure that halts critical processes, leaving the system offline until the services or server are manually restarted. As a result, access control readers cease to function, and potential failures may occur in third-party integrations. Since the exploit requires no privileges or user interaction and is trivial to automate, the impact on availability is high, and the effect extends to interconnected systems.

Title: BioStar 2 (server) de Suprema, Description: Una excepción no controlada en Suprema BioStar 2 (servidor), versiones 2.9.8, 2.9.10 y 2.9.11, que permite a un atacante remoto no autenticado causar una denegación de servicio (DoS) enviando solicitudes HTTP POST al endpoint ‘/api/migration’. Esta solicitud desencadena un fallo que detiene procesos críticos, dejando el sistema fuera de línea hasta que los servicios o el servidor se reinicien manualmente. Como resultado, los lectores de control de acceso dejan de funcionar y pueden producirse fallos potenciales en integraciones de terceros. Dado que el exploit no requiere privilegios ni interacción del usuario y es trivial de automatizar, el impacto en la disponibilidad es alto y el efecto se extiende a los sistemas interconectados.
