The vulnerability is due to improper handling, processing, and termination of HTTP and HTTPS connections. An attacker could exploit this vulnerability by sending multiple HTTP or HTTPS requests to any management-enabled interfaces of the affected system. A full TCP three-way handshake is required to exploit this vulnerability. An exploit could allow the attacker to prevent management access via the GUI. A hard reboot of the affected system is needed to restore full functionality.
