Descriptions

This vulnerability allows remote attackers to execute arbitrary code on affected installations of NETGEAR ProSAFE Network Management System 1.6.0.26. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the SettingConfigController class. When parsing the fileName parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-12121.

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de NETGEAR ProSAFE Network Management System versión 1.6.0.26. Aunque es requerida una autenticación para explotar esta vulnerabilidad, el mecanismo de autenticación existente puede ser omitido. El fallo específico se presenta dentro de la clase SettingConfigController. Cuando se analiza el parámetro fileName, el proceso no comprueba apropiadamente una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de SYSTEM. Era ZDI-CAN-12121
