A problem was identified that could potentially cause a security vulnerability in certain versions of WebLogic Server. A patch is available to correct this problem (see Section II). BEA Systems treats potential security problems with a high degree of urgency and endeavors to take appropriate steps to help ensure the security of our customers' systems. As a result, BEA Systems strongly suggests the following actions:

I. Advisory
A WebLogic JMS Bridge configured without destination username and password could transfer messages to a queue protected with a security access policy. The Bridge may also ignore the username and password configured with the bridge destination when connection URL is not defined.
A patch is available to correct this issue by enforcing the correct use of the username and password defined in the Bridge-destination configuration. The Bridge will use "anonymous" when no username or password has been configured for a destination.
