CWE Code: 287
Vulnerability Type: privilege_escalation
CVSS Score: 6.0
CWE Name:  Improper Authentication
Summary: 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.
Access Authentication: SINGLE
Access Complexity: MEDIUM
