Summary

Brocade Fabric OS versions before 10.0.1 contain a path traversal flaw in the REST API management interface that handles USB storage operations. An authenticated user with USB management privileges can manipulate requested target paths to delete arbitrary files or directories on the switch's local root filesystem, outside the intended USB mount point. The attacker needs valid credentials and USB management privileges, and the attack is reachable over an adjacent network.
