A race condition vulnerability exists in the request processing logic of the REST management interface on Brocade Fabric OS versions before 10.0.1. When handling concurrent incoming network management FCIP requests, a timing window exists between when a request populates the address variable and when the service constructs and returns the response context. As a result, the first request adopts the modified context, causing the service to return sensitive management details or configuration data belonging to the second context back to the original requester.
