"value": "Nextcloud Server before 9.0.54 and 10.0.1 & ownCloud Server before 9.1.2, 9.0.6, and 8.2.9 suffer from SMB User Authentication Bypass. Nextcloud/ownCloud include an optional and not by default enabled SMB authentication component that allows authenticating users against an SMB server. This backend is implemented in a way that tries to connect to a SMB server and if that succeeded consider the user logged-in. The backend did not properly take into account SMB servers that have any kind of anonymous auth configured. This is the default on SMB servers nowadays and allows an unauthenticated attacker to gain access to an account without valid credentials. Note: The SMB backend is disabled by default and requires manual configuration in the Nextcloud/ownCloud config file. If you have not configured the SMB backend then you're not affected by this vulnerability."

"value": "Nextcloud Server en versiones anteriores a 9.0.54 y 10.0.1 y ownCloud Server en versiones anteirores a 9.1.2, 9.0.6 y 8.2.9 sufren de Bypass de autenticaci\u00f3n de usuario SMB. Nextcloud/ownCloud Incluye un componente de autenticaci\u00f3n SMB opcional y no predeterminado que permite autenticar a los usuarios en un servidor SMB. Este backend se implementa de una manera que intenta conectarse a un servidor SMB y si eso sucede considerar al usuario conectado. El backend no tom\u00f3 correctamente en cuenta los servidores SMB que tienen cualquier tipo de configuraci\u00f3n an\u00f3nima. Este es el valor predeterminado en los servidores SMB en la actualidad y permite a un atacante no autenticado acceder a una cuenta sin credenciales v\u00e1lidas. Nota: El servidor SMB est\u00e1 deshabilitado de forma predeterminada y requiere una configuraci\u00f3n manual en el archivo de configuraci\u00f3n Nextcloud/ownCloud. Si no has configurado el servidor SMB, no te ver\u00e1s afectado por esta vulnerabilidad."
