Description
The HTTP Connector component of TIBCO Software Inc.'s TIBCO ActiveMatrix BusinessWorks contains a vulnerability that theoretically allows unauthenticated HTTP requests to be processed by the BusinessWorks engine even when authentication is required.

The BusinessWorks engine might instead use credentials from a prior HTTP request for authorization purposes. Affected releases are TIBCO Software Inc. TIBCO ActiveMatrix BusinessWorks: versions up to and including 6.4.2.
