Description
A vulnerability has been identified in the data collection service of Brocade ASCG versions before 3.5.0. An API endpoint within the data collector service fails to perform authentication or authorization checks on incoming requests. An attacker with network access to the service can instruct the application to establish SSH connections to arbitrary hosts and execute arbitrary system commands, effectively turning the appliance into an unauthenticated proxy or execution vector.
