<p>There is a workaround that addresses this vulnerability. Administrators can disable the anonymous binds on the external authentication server.</p> <p><strong>Note:</strong> This action must be performed on the server that handles external authentication. Administrators should work with their networking teams to implement this workaround. The external authentication feature provided by the Cisco Secure devices should not be hindered by this workaround.</p> <p>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.</p>
