A critical authorization bypass vulnerability exists in the Management Server handling of Brocade Fabric OS versions before 10.0.1.

Successful exploitation allows an unauthorized peer switch to execute administrative actions on the target device, including resetting administrative passwords, initiating system reboots, and triggering firmware downloads.
