Descriptions

The NETGEAR WNR2000v5 router allows an administrator to perform sensitive actions by invoking the apply.cgi URL on the web server of the device. This special URL is handled by the embedded web server (uhttpd) and processed accordingly. The web server also contains another URL, apply_noauth.cgi, that allows an unauthenticated user to perform sensitive actions on the device. This functionality can be exploited to change the router settings (such as the answers to the password-recovery questions) and achieve remote code execution.

El router NETGEAR WNR2000v5 permite a un administrador realizar acciones sensibles invocando a la URL apply.cgi en el servidor web del dispositivo. Esta URL especial es manejada por el servidor web embebido (uhttpd) y procesada como corresponde. El servidor web también contiene otra URL, apply_noauth.cgi, que permite a un usuario no autenticado realizar acciones sensibles en el dispositivo. Esta funcionalidad puede ser explotada para cambiar la configuración del router (tal como la respuestas a las preguntas de recuperación de contraseña) y logar la ejecución remota de código.

Netgear WNR2000 suffers from a remote code execution vulnerability and various other security issues.
