Authentication is not required to exploit this vulnerability. The specific flaw exists within the acsd service, which listens on TCP port 5916 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-9853."},{"lang":"es","value":"Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de enrutadores NETGEAR R6700 versión V1.0.4.84_10.0.58 con versiones de firmware 1.0.4.84_10.0.58. No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta dentro del servicio acsd, que escucha en el puerto TCP 5916 por defecto. El problema resulta de una falta de comprobación apropiada de la longitud de los datos suministrados por parte del usuario antes de copiarlos a un búfer en la región stack de la memoria de longitud fija.
