Summary

Brocade Fabric OS versions before 10.0.1 contain a race condition in the request processing logic of the REST management interface. A timing window during concurrent FCIP management requests lets one request return the response context of another, exposing that requester's management details or configuration data (CWE-362). An adjacent network attacker with low privileges can trigger it, though the attack is complex.

Description from the CNA

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.
