As a workaround, customers who do not require the detection of a steady, high rate of RADIUS requests for their daily operations may disable the detection to prevent the exploitation of this vulnerability. To disable this feature, log in to the web management GUI with super admin privileges. Choose Administration > System > Settings > Protocols > RADIUS and uncheck Detect High Rate of RADIUS Requests.
While this workaround 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.
