There are no workarounds that address this vulnerability. However, as a mitigation, customers who do not require the SSH service can disable it either by using the ssh-server disable CLI command or by unchecking the SSH checkbox on the Misc Settings page in the web UI.
While this mitigation has been deployed and was proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.
