Summary

The Kerberos plugin in Apache Solr is susceptible to serious security flaws related to delegation token functionality. When configured to use the SecurityAwareZkACLProvider type of ACL provider (such as SaslZkACLProvider), sensitive security configurations can inadvertently be accessed by users other than the designated Solr super user. This leakage opens the door for attackers to manipulate these configurations for privilege escalation, leading to unauthorized access, exposure of private data, or disruption of operations within the Solr cluster. This vulnerability has been addressed and resolved in Apache Solr version 6.6.1 and later.

Affected Version(s)

Apache Solr 6.2.0 to 6.6.0
