Low 2.1
In plain English
A low-severity race condition in Fabric OS from Brocade. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 1% of all known vulnerabilities).
Official 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.
