A security issue has been reported in JRun, which can result in malicious users gaining access to another user's session.
The problem is caused due to a race condition where JRun in certain situations during heavy load may generate the same authentication token for two different sessions. This may allow a malicious authenticated user to access another user's session.
The security issue affects the following versions:
* ColdFusion MX 7.0 Enterprise Multi-Server Edition
* ColdFusion MX 6.1 Enterprise with JRun
* JRun 4.0
