Technical description
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.
Remediation
Check the references section for vendor advisories and patches from broadcom. Update fabric_operating_system to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
