Description
Apache Solr from 6.0.0 through 8.11.2, from 9.0.0 before 9.4.1 is affected by an Unrestricted Upload of File
with Dangerous Type vulnerability which can result in remote code execution in the context of the user running
Apache Solr. When Apache Solr creates a Collection, it will use a specific directory as the classpath and load
some classes from it. The backup function of the Collection can export malicious class files uploaded by
attackers to the directory, allowing Solr to load custom classes and create arbitrary Java code. Execution
can further bypass the Java sandbox configured by Solr, ultimately causing arbitrary command execution.
