A vulnerability, which was classified as critical, was found in Apache Solr 8.1.1/8.2.0. Affected is an unknown code block of the file solr.in.sh of the component Configuration File. The manipulation with an unknown input leads to a privilege escalation vulnerability. CWE is classifying the issue as CWE-434. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The 8.1.1 and 8.2.0 releases of Apache Solr contain an insecure setting for the ENABLE_REMOTE_JMX_OPTS configuration option in the default solr.in.sh configuration file shipping with Solr. If you use the default solr.in.sh file from the affected releases, then JMX monitoring will be enabled and exposed on RMI_PORT (default=18983), without any authentication. If this port is opened for inbound traffic in your firewall, then anyone with network access to your Solr nodes will be able to access JMX, which may in turn allow them to upload malicious code for execution on the Solr server.

The weakness was published 11/18/2019 (Website). The advisory is shared for download at lists.apache.org. This vulnerability is traded as CVE-2019-12409 since 05/28/2019. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 11/19/2019).
