Vulnerability from variot

An Improper Input Validation vulnerability in DataImportHandler of Apache Solr 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 which can lead to user impersonation on SMB Shares or, in a worse-case scenario, Remote Code Execution This issue affects all Apache Solr versions prior to 8.11.1. This issue only affects Windows. Apache Solr Exists in a past traversal vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Apache Solr is a search server based on Lucene (a full-text search engine) of the Apache Foundation in the United States. The product supports level search, vertical search, highlight search results, etc.

Apache Solr has security flaws that could allow attackers to gain wider access to the network, potentially leading to SMB attacks
