CVE-2019-7611: Elastic Elasticsearch

High severity, CVSS 8.1. EPSS: 2.1% chance of exploitation in the next 30 days.

A permission issue was found in Elasticsearch versions before 5.6.15 and 6.6.1 when Field Level Security and Document Level Security are disabled and the _aliases, _shrink, or _split endpoints are used . If the elasticsearch.yml file has xpack.security.dls_fls.enabled set to false, certain permission checks are skipped when users perform one of the actions mentioned above, to make existing data available under a new index/alias name. This could result in an attacker gaining additional permissions against a restricted index.

Affected products

• Elastic Elasticsearch: before 5.6.15 (fixed in 5.6.15); from 6.0.0, before 6.6.1 (fixed in 6.6.1)
