What is CVE-2018-1308?

This vulnerability in Apache Solr allows attackers to exploit the XML external entity expansion (XXE) in the &dataConfig=<inlinexml> parameter of Solr's DataImportHandler. By manipulating this parameter, an attacker could leverage protocols like file, ftp, or http to read arbitrary files from the Solr server or the internal network. This poses significant risks to the confidentiality of sensitive data stored on the server and emphasizes the need for immediate remediation.
