Summary

A vulnerability in the GUI function in the web framework code could allow an 
unauthenticated, remote attacker to cause the GlassFish process to become 
unresponsive, resulting in a partial denial of service (DoS) condition.

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.

What Is a Cisco Security Notice?

Security Notices to inform customers of low- to mid-level severity security 
issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for 
these issues should contact their normal support channels. Free software 
updates will not be provided for issues that are disclosed through a Cisco
