DescriptionA flaw was found in Apache Solr. The Schema Designer was introduced to allow users to more easily configure and test new Schemas and configSets. However, it may load untrusted configSets, which can allow an unauthenticated user to load external libraries when used in the Schema Designer. This issue may allow an attacker to perform remote code execution on the affected system.A flaw was found in Apache Solr.
