Apache Solr’s Kerberos plugin can be configured to use delegation tokens,
which allows an application to reuse the authentication of an end-user or
another application. There are two issues with this functionality (when
using SecurityAwareZkACLProvider type of ACL provider e.g.
SaslZkACLProvider). Firstly, access to the security configuration can be
leaked to users other than the solr super user. Secondly, malicious users
can exploit this leaked configuration for privilege escalation to further
expose/modify private data and/or disrupt operations in the Solr cluster.
The vulnerability is fixed from Apache Solr 6.6.1 onwards.
