These vulnerabilities are due to insufficient validation of user-supplied input that is processed by the web-based management interface. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information.
