An unauthenticated attacker could invoke the same URL used by the product's default-installation / first-admin creation page and create a new administrative account remotely. By gaining admin privileges, the attacker can change the ATM configuration resulting in redirected funds. Public vendor advisories and multiple independent writeups describe the vulnerability as a call to the page used for initial/default installation / first administration user creation; General Bytes has not publicly published the exact endpoint/parameter name. The issue was actively exploited in the wild against cloud-hosted and standalone CAS deployments (scanning exposed CAS instances on ports 7777/443), and publicly acknowledged by the General Bytes in September 2022."},{"lang":"es","value":"El General Bytes Crypto Servidor de Aplicaciones (CAS) a partir de la versión 20201208 anterior a la 20220531.38 (backport) y 20220725.22 (mainline) contiene una omisión de autenticación en la interfaz web de administración. Un atacante no autenticado podría invocar la misma URL utilizada por la página de instalación predeterminada / creación del primer administrador del producto y crear una nueva cuenta administrativa de forma remota. Al obtener privilegios de administrador, el atacante puede cambiar la configuración del cajero automático, lo que resulta en fondos redirigidos.
