Security readout for executives and security teams
Some Apache Solr deployments allowed non-super users to obtain security configuration details and use them to gain more privileges. The risk applies to Solr 6.2.0 through 6.6.0 when Kerberos delegation tokens and SecurityAwareZkACLProvider-style ACLs are in use. Successful abuse could expose or change private data or disrupt the Solr cluster. Exposure is limited to Apache Solr 6.2.0 through 6.6.0 deployments using Kerberos delegation tokens with SecurityAwareZkACLProvider-type ACL providers. Solr deployments outside those versions or not using this configuration are not identified as affected in the provided sources. Treat this as high priority for affected secured Solr clusters because it concerns privilege escalation and potential private data modification. It is less urgent for environments that can prove they are outside the affected versions or do not use the vulnerable Kerberos delegation-token configuration. Mitigation focus: Upgrade affected Apache Solr clusters to 6.6.1 or later.; Prioritize clusters using Kerberos delegation tokens and SaslZkACLProvider-style ACLs.; If upgrade is delayed, check Apache advisory guidance for supported interim controls..
