To exploit these vulnerabilities, the attacker must have valid administrative credentials.  These vulnerabilities are due to improper sanitization of user input to the web-based management interface. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request. A successful exploit could allow the attacker to download arbitrary files from an affected system.
