There is a workaround that addresses this vulnerability. As explained in the Details ["#details"] section of this advisory, administrators should verify the LDAP authentication server configuration and ensure that failing search queries do not return non-empty matching result arrays. Methods vary depending on the LDAP server that is deployed. For further guidance, refer to the documentation for the specific LDAP installation.
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.
