QID 150446: Apache Solr Information Disclosure Vulnerability (CVE-2021-29262)

Apache Solr is an open-source enterprise search platform which is on Apache Lucene.

The installed version of Apache Solr is vulnerable to Information Exposure. When starting Solr, 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.

Affected Versions:
before version 8.8.2

Successful exploitation would lead to Information Disclosure vulnerability, which can help the attacker carry out further attacks and obtain sensitive information.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 4.3 severity.

Solution

Upgrade to Solr 8.8.2 or later.
