This vulnerability in Apache Solr 6.0.0 to 6.6.4 and 7.0.0 to 7.3.1 relates to an XML external entity expansion (XXE) in Solr config files (currency.xml, enumsConfig.xml referred from schema.xml, TIKA parsecontext config file). In addition, Xinclude functionality provided in these config files is also affected in a similar way. The vulnerability can be used as XXE using file/ftp/http protocols in order to read arbitrary local files from the Solr server or the internal network. The manipulated files can be uploaded as configsets using Solr's API, allowing to exploit that vulnerability.

Security readout for executives and security teams

Apache Solr versions 6.0.0 through 6.6.4 and 7.0.0 through 7.3.1 can be tricked into reading files through crafted configuration uploaded as a configset. For businesses, the main concern is exposure of sensitive files on the Solr server or reachable internal network resources. Exposure is most likely where affected Solr versions allow configset uploads by untrusted users, unauthenticated users, or externally reachable admin/API paths. Embedded or downstream Solr deployments may also matter; the bundle cites NetApp advisory material but does not list affected NetApp products. Treat this as high priority for internet-facing or shared Solr environments because it can expose sensitive server files. Internal, tightly administered Solr deployments still need validation, but urgency depends on who can upload configsets and reach Solr APIs. Mitigation focus: Inventory Apache Solr versions and identify 6.0.0-6.6.4 or 7.0.0-7.3.1 deployments.; Follow Apache Solr guidance and move affected deployments outside the vulnerable version ranges.; Restrict Solr APIs and admin endpoints to trusted networks and authenticated administrators..
