CVE-2022-4980
General Bytes Crypto Application Server (CAS) Unauthenticated Creation of Admin Account via Default-installation/First-admin Page
Description
General Bytes Crypto Application Server (CAS) beginning with version 20201208 prior to 20220531.38 (backport) and 20220725.22 (mainline) contains an authentication bypass in the admin web interface. 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.

Action Type Old Value New Value Added Translation Title: Crypto Application Server (CAS) de General Bytes, Description: 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. Los avisos públicos del proveedor y múltiples informes independientes describen la vulnerabilidad como una llamada a la página utilizada para la instalación inicial/predeterminada / creación del primer usuario de administración; General Bytes no ha publicado públicamente el nombre exacto del endpoint/parámetro. El problema fue explotado activamente en la naturaleza contra implementaciones de CAS alojadas en la nube y autónomas (escaneando instancias de CAS expuestas en los puertos 7777/443), y reconocido públicamente por General Bytes en septiembre de 2022. -
