Workarounds & Mitigations

CVE ID Workaround and Mitigation
CVE-2022-33186 EZServer Component - To remove any exposure to this vulnerability, Brocade Fabric OS (FOS) switch administrators must disable EZServer support or upgrade to a version of Brocade Fabric OS that has the EZServer module removed.
Disabling EZServer is accomplished through the use of 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.
