We have recently become aware of a security vulnerability in the Apache Struts web framework used in the caIntegrator web application. Due to this vulnerability, we have taken down the public NCI instance of caIntegrator and we are upgrading to Struts version 2.3.15.1 which addresses the issue. We will make this patch available to the community as soon as we have completed development and testing, anticipated by August 30, 2013. Until this patch is available, we recommend that you disable access to caIntegrator outside of your firewall.
