This vulnerability is due to insufficient validation of user-supplied input that is processed by the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface or access sensitive, browser-based information.
