Tijdelijke oplossingen en risicobeperking

To remove any exposure to this vulnerability, Brocade Fabric OS switch administrators must disable EZServer support or upgrade to a version of FOS that has the EZServer module removed.

Disabling EZServer is accomplished by using the CLI command "configurechassis." Disabling the EZServer in the switch configuration prevents any exposure to this vulnerability. This option is only available on FOS versions v8.1.0b and later. Customers running on older versions of FOS, including v7.4.2j, do not have this option and must upgrade to FOS v7.4.2j1 to protect their switches.

Customers that elect to upgrade their FOS version can obtain a patch with the EZServer module removed:

  • FOS v9.1.1_01 and higher versions
  • FOS v9.0.1e1 and higher versions
  • FOS v8.2.3c1 and higher versions
  • FOS v7.4.2j1 and higher versions
These patches can be obtained from their standard support customer portal or by contacting their support organization.

Example showing how to disable the EZServer module: 
brocadeswitch:admin> configurechassis
Configure...
cfgload attributes (yes, y, no, n): [no]
ssl attributes (yes, y, no, n): [no]
webtools attributes (yes, y, no, n): [no] y
...
Login Session Timeout (in secs): (60..432000) [7200]
EZserver Enabled (yes, y, no, n): [yes] no
...
brocadeswitch:admin >

Notes:
The following actions reenable EZServer on Fabric OS versions that do not have the EZServer module entirely removed:
  • firmwarecleaninstall
  • config removall
  • configdefault
  • factory reset
