CVE-2020-10929

Estado: ModificadaAlta (8.8)—

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of string table file uploads. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-9768.

No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta en el manejo de las cargas de archivos de tabla de cadenas. El problema resulta de la falta de una comprobación apropiada de los datos suministrados por el usuario, lo que resulta en un desbordamiento de enteros antes de asignar un búfer. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario administrador. Fue ZDI-CAN-9768"
