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?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco 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 Security Notice.

For additional information about Cisco PSIRT publications, see the Cisco Security Vulnerability Policy at http://www.cisco.com/web/about/security/psirt/security_vulnerability_policy.html

Customers Using Third-Party Support Organizations

Customers may have Cisco products that are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers. For these products, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed.
