CVE-2018-8010: This vulnerability in Apache Solr 6.0.0 to 6.6.3, 7.0.0 to 7.3.0 relates to an XML external entity expansio...

This vulnerability in Apache Solr 6.0.0 to 6.6.3, 7.0.0 to 7.3.0 relates to an XML external entity expansion (XXE) in Solr config files (solrconfig.xml, schema.xml, managed-schema). 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. Users are advised to upgrade to either Solr 6.6.4 or Solr 7.3.1 releases both of which address the vulnerability. Once upgrade is complete, no other steps are required. Those releases only allow external entities and Xincludes that refer to local files / zookeeper resources below the Solr instance directory (using Solr's ResourceLoader); usage of absolute URLs is denied. Keep in mind, that external entities and XInclude are explicitly supported to better structure config files in large installations. Before Solr 6 this was no problem, as config files were not accessible through the APIs.

Security readout for executives and security teams

Apache Solr versions 6.0.0 through 6.6.3 and 7.0.0 through 7.3.0 can process unsafe external references in configuration files. A successful attack could let an attacker read files from the Solr server or reach internal network resources from that server. Upgrade guidance is available from Apache. Exposure is most likely where affected Solr versions are deployed and configuration APIs or config sets are reachable by users who can influence Solr configuration content. Systems on Solr 8.4.1 are not indicated as affected by the cited Solr user thread context. Prioritize remediation for internet-facing or shared Solr environments because file disclosure from search infrastructure can expose credentials, application secrets, and internal topology. The fix path is straightforward: upgrade to the Apache-recommended versions or later supported releases. Mitigation focus: Upgrade Solr 6.x deployments to Solr 6.6.4 or later supported releases.; Upgrade Solr 7.x deployments to Solr 7.3.1 or later supported releases.; After the documented upgrade, Apache states no additional steps are required..
