Do not have users accessing Solr directly. Have your own secure web frontend/ own APIs for it. In this way you can control secure access.
Secure Solr with https and Kerberos. Have for your web frontend only access rights needed and for your admins only the access rights they need. Automate deployment of configurations through the APIs. Secure Zookeeper (if in cloud mode) with ssl and authentication (eh Kerberos). Make sure that connection to those two are only allowed for the web frontend and admins ( for the latter have a dedicated jumphost from which connections are allowed). > Am 11.02.2020 um 10:55 schrieb Martin Frank Hansen (MHQ) <m...@kmd.dk>: > > Hi, > > I was wondering how others are handling solr – injection in their solutions? > > After reading this post: > https://www.waratek.com/apache-solr-injection-vulnerability-customer-alert/ I > can see how important it is to update to Solr-8.2 or higher. > > Has anyone been successful in injecting unintended queries to Solr?
