An unauthenticated attacker can exploit this vulnerability to authenticate as an admin user without needing to provide a password, thereby gaining full control of the device. (Whenever an admin logs into My Cloud, a server-side session is created that is bound to the user's IP address. After the session is created, it is possible to call authenticated CGI modules by sending the cookie username=admin in the HTTP request. The invoked CGI will check if a valid session is present and bound to the user's IP address.) It was found that it is possible for an unauthenticated attacker to create a valid session without a login. The network_mgr.cgi CGI module contains a command called \"cgi_get_ipv6\" that starts an admin session -- tied to the IP address of the user making the request -- if the additional parameter \"flag\" with the value \"1\" is provided. Subsequent invocation of commands that would normally require admin privileges now succeed if an attacker sets the username=admin cookie."}, {"lang": "es", "value": "Se ha descubierto que el dispositivo Western Digital My Cloud hasta las versiones 2.30.x se ve afectado por una vulnerabilidad de omisi\u00f3n de autenticaci\u00f3n.
