CVE-2021-29262

Misapplied Zookeeper ACLs can result in leakage of configured authentication and authorization settings

Published Apr 13, 2021 CVSS 3.1 · 7.5 High EPSS 6.7% KEV · Not listed
Description
When starting Apache Solr versions prior to 8.8.2, configured with the SaslZkACLProvider or VMParamsAllAndReadonlyDigestZkACLProvider and no existing security.json znode, if the optional read-only user is configured then Solr would not treat that node as a sensitive path and would allow it to be readable. Additionally, with any ZkACLProvider, if the security.json is already present, Solr will not automatically update the ACLs.

Remediation

Vendor Workaround

Manually set appropriate ACLs on /security.json znode.
