Descriptions
This vulnerability allows remote attackers to disclose sensitive information and delete arbitrary files 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 ConfigFileController class. When parsing the realName parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose sensitive information or to create a denial-of-service condition on the system. Was ZDI-CAN-12125.
Esta vulnerabilidad permite a atacantes remotos divulgar información confidencial y eliminar archivos arbitrarios 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 ConfigFileController. Cuando se analiza el parámetro realName, el proceso no comprueba apropiadamente una ruta suministrada por el usuario antes de usarla en operaciones de archivo. Un atacante puede aprovechar esta vulnerabilidad para divulgar información confidencial o crear una condición de denegación de servicio en el sistema. Era ZDI-CAN-12125
