Advisory ID gitlab/maven/org.apache.solr/solr-core/CVE-2017-9803
Aliases CVE-2017-9803
Summary Privilege escalation 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.
