Descriptions

D-Link DNS-320L firmware before 1.04b12, DNS-327L before 1.03b04 Build0119, DNR-326 1.40b03, DNS-320B 1.02b01, DNS-345 1.03b06, DNS-325 1.05b03, and DNS-322L 2.00b07 allow remote attackers to bypass authentication and log in with administrator permissions by passing the cgi_set_wto command in the cmd parameter, and setting the spawned session's cookie to username=admin.

DNS-320L firmware anterior a la versión 1.04b12, DNS-327L anterior a la versión 1.03b04 Build0119, DNR-326 versión 1.40b03, DNS-320B versión 1.02b01, DNS-345 versión 1.03b06, DNS-325 versión 1.05b03, y DNS-322L versión 2.00b07 de D-Link, permite a los atacantes remotos omitir la autenticación e iniciar sesión con los permisos de administrador omitiendo el comando cgi_set_wto en el parámetro cmd y ajustando la cookie de sesión creada en username=admin.

SEARCH-LAB performed an independent security assessment on four different D-Link devices. The assessment has identified altogether 53 unique vulnerabilities in the latest firmware (dated 30-07-2014). Several vulnerabilities can be abused by a remote attacker to execute arbitrary code and gain full control over the devices.
