Please visit the HPE Support Center to download the latest software: Version 9.1.1_01 or later FOS firmware for HPE B-Series products Version 9.0.1e1 or later FOS firmware for HPE B-Series products Version 8.2.3c1 or later FOS firmware for HPE B-Series products Version 7.4.2j1 or later FOS firmware for HPE B-Series products Workaround Customers may consider the below workaround where an update is not feasible. To remove any exposure to this vulnerability, Brocade Fabric OS (FOS) switch administrators must disable EZServer support. Disabling EZServer is accomplished through the use of the CLI command configurechassis. Disabling the EZServer in the switch configuration will prevent any exposure to this vulnerability. This option is only available on Brocade Fabric OS versions v8.1.0b and higher. Customers running on older versions of Brocade Fabric OS, including v7.4.2j, do not have this option and must upgrade to Brocade Fabric OS v7.4.2j1 to protect their switches.
