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.
