A command injection vulnerability in Brocade Fabric OS before 9.2.0c, and 9.2.1 through 9.2.1a on IP extension platforms could allow a local authenticated attacker to perform a privileged escalation via crafted use of the portcfg command.
This specific exploitation is only possible on IP Extension platforms: Brocade 7810, Brocade 7840, Brocade 7850 and on Brocade X6 or X7 directors with an SX-6 Extension blade installed. The attacker must be logged into the switch via SSH or serial console to conduct the attack.
