Overview
org.apache.solr:solr-core is an open source enterprise search platform built on Apache Lucene
Affected versions of this package are vulnerable to Improper Input Validation in DataImportHandler, which allows an attacker to provide a Windows UNC path resulting in an SMB network call being made from the Solr host to another host on the network. If the attacker has wider access to the network, this may lead to SMB attacks, which may result in the exfiltration of sensitive data such as OS user hashes (NTLM/LM hashes). In case of misconfigured systems, SMB relay attacks can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution.
