For some IBM Rational Software products, including IBM Rational Insight, there is a potential Denial of Service (DoS) security exposure when using Web based applications due to Java HashTable implementation vulnerability.
Your product is deployed on IBM WebSphere Application Server version 6.0, 6.1, 7.0, or 8.0 server and you are therefore impacted by a security vulnerability which can cause performance or denial of service (DoS) issues. You are advised to read the instructions in the linked documents section and update your application servers to correct this issue:
4031821: PM53930: Collisions in HashTable May Cause DoS Vulnerability
Reference: CVE-2012-0193: IBM WebSphere Application Server (WAS) 6.0 through 22.214.171.124, 6.1 before 126.96.36.199, 7.0 before 188.8.131.52, and 8.0 before 184.108.40.206 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
